2. Performance and structure
2.1 Structure diagram
Figure1. Cone crusher structure
2.2 Production capacity
The crushing capacity is related to the type of material. The production capacity in the
statistical table is the value under the following conditions:
1. The material of the crusher is ordinary ore with a specific gravity of about

1.6T/M.
2. Feeding method: continuous feeding without the cone crusher being idling
3. Dry ore, uniform size, easy to feed
2.3 cone crusher working principle
During operation, the eccentric sleeve is rotated by the motor through the V-belt,
the pulley, the drive shaft, the bevel gear, and the large bevel gear, the broken
conical axis is rotated and oscillated under the eccentric bushing, so that the
surface of the broken wall is close to the surface of the rolling wall. Thereby, the
material is continuously crushed, crushed and bent in the annular crushing cavity
composed of the fixed cone and the moving cone. After multiple extrusions,
impacts and bending, the material is broken to the required particle size and
discharged through the lower part.

2.5 general structure of the machine
The cone crusher frame is an integral cast steel structure, which is subjected to
stress-relieving and tempering after casting, and has reinforcing ribs at high stress
points in the heavy load part.
The power drive is completed by a pair of heavy-duty bevel gears that seal the
inner cavity of the drive shaft to prevent oil leakage.
The cone crusher has a copper frame and tapered sleeve, a steel bowl-shaped tile
seat and tile. The seal ring for dust protection is floated by a spring placed on the
bowl-shaped tile seat to regulate during operation of the machine.
Hydraulic adjustment mechanism for quickly adjusting the size of the discharge
opening. After determining the size of the discharge opening, it is locked by the
hydraulic locking mechanism. The hydraulic clearing system is completed by the

clearing cylinder placed on the bottom plate of the rack. The recommended
clearance distance is 60mm.
The lubrication system consists of a cylinder, an oil pump, a flow meter, and a
pipeline. The machine will automatically shut down when the oil temperature is too
high or the flow rate is too slow.
The iron release is spring-loaded.
2.6 Operation Overview
The cone crusher is mainly used for secondary and tertiary crushing. A cone and a
crushing wall are mounted on the main shaft in the center of the frame, and the
spherical surface of the body is placed on the bowl seat, and the lower end of the
spindle is fitted into the eccentric sleeve.Since the frame hole and the eccentric
sleeve hole are eccentric, the rotation of the eccentric sleeve drives the spindle and
the body to swing and rotate. The rolling sleeve is installed under the adjusting
sleeve, and together with the crushing wall constitutes a crushing chamber. The
hopper ensures that the material falls evenly on the distribution tray, and the rotary
motion ensures that the material falls evenly in the crushing chamber, and the
material is continuously discharged after being broken. The support sleeve
connected to the adjustment sleeve is mounted on the frame body through the
outer release spring. If the material is mixed with a special hard material (such as an
iron block), the support sleeve floats under the action of the release spring to allow
foreign matter to pass, thereby preventing damage to the machine. The foreign

matter is restored by the rear support sleeve, and the machine continues to work
normally.
1. Machine installation requirements
1.1 Foundation
It can be operated according to the general installation procedure of the general
machine during installation. When carrying out the basic design, it is necessary to
ensure the height required for the crusher to discharge, and the conveyor belt can
pass smoothly.
In general, the supplier will provide a basic construction drawing for the user's
reference.
1.2 Lifting Equipment
Lifting equipment is required for the installation of the machine, periodic
inspections, replacement of consumables and maintenance. The user must install
the vehicle and at least install the overhead monorail.
The selection of lifting equipment requires an understanding of the weight of the
various parts of the machine as well as the size of the space.(See Figure 1, 2 and
Tables 2 and 3)

2. Preparation before installation
After the machine arrives at the site, the packing list should be carefully checked to
check whether the parts are defective or not. If you find a defect, please contact us
in time.
Wash the machine before installation. It should be cleaned manually with a clean
rag, do not scrape it with sharp props. The oil cylinder should be thoroughly
cleaned, and the water supply and drainage pipelines should be carefully inspected
and installed without any foreign matter.
General instructions for installation
1.1 frame installation
1. Strict verticality and level should be maintained when installing the frame. The
center line of the base can be inspected on the ring working surface of the base
with a level and a Plumb bob.(The whole machine installation also requires vertical
and horizontal)
2. After adjusting the level of the base with the adjusting wedge iron, tighten the
anchor screw for the second grout.
3. After the secondary grouting is hardened, check the horizontal and verticality of
the rack according to the installation requirements of the frame to ensure that the
machine can work reliably. Otherwise, the copper sleeve will be contacted with the
eccentric sleeve on one side and the dust-proof device will not work properly.

Figure3 Frame installation diagram
1.2 Installation of drive shaft frame and pulley
(1) When installing the drive shaft, adjust the gasket between the base and the
flange flange of the drive shaft bracket.
(2) After the drive shaft is installed, check the dimensions of the drive gear with the
template (see Figure 4).
(3) The axial movement of the transmission gear shaft should be 0.4-0.6mm.
(4) If you need to disassemble the drive shaft, you can use the square head fixing
screw on the flange of the drive shaft to push out. Do not screw the square head
screw when the drive shaft is not removed.

A. Installation of the drive shaft frame:
(1) After the drive shaft is installed, the large gear on the eccentric sleeve is driven
to mesh the pinion of the transmission shaft with the large gear.
(2) The tooth gap between the drive large gear and the pinion gear should not be
too loose or too tight.
(3) Install large diameter O-rings as shown to prevent oil leakage during
installation.
(4) Place the drive pedestal guard on the pinion end of the drive pedestal.
(5) Place a long tube on the belt end of the drive shaft to balance the weight of the
pinion end that is heavier than the part
(6) Using the lifting device, carefully slide the drive pedestal into the frame and
push it in as far as possible.
(7) Use 3 special hex jack screws to pass through the holes in the flange of the drive
shaft bracket and screw them into the screw holes in the frame (see figure).
(8) Because there is an interference fit between the two flanges of the drive shaft
frame, in order to prevent the movement, the jack screws should be tightened one
by one and screwed straight to the bottom of the threaded hole of the frame.
(9) Unscrew the jack screws, add spacers or spacers between the flanges, and screw
the jack screws straight to the bottom of the threaded holes.
(10) Remove the jack screw and replace it with a normal hex screw.
(11) Tighten these standard hex screws in turn and continue to push the drive
pedestal into the frame until the drive yoke is tightened onto the frame.(See drive

shaft seal diagram)
Figure4 Drive shaft frame installation diagram
Figure5 Transmission assembly drawing

Figure6 Drive shaft seal Figure7 Transmission shaft frame disassembly diagram
B. Crusher pulley installation
(1) When installing the pulley, first check the taper and inner hole of the taper
sleeve, the inner taper hole of the pulley and the drive shaft for cleanness, burr,
abrasion and impurities.
(2) Pull the drive shaft toward the drive end until the thrust washer of the pinion is
placed against the drive shaft.
(3) Tap the oil ring with a wooden block so that it rests against the outer sleeve of

the drive shaft.
(4) Check the drive shaft to make sure it cannot move in the axial direction. If the
drive shaft still has a slight amount of turbulence, add a pulling force to the shaft
and tap the oil ring to abut the outer bushing of the drive shaft.
(5) Place the key in the drive shaft keyway.
(6) Loosen the locking screw and set screw on the pulley sleeve and slide the sleeve
onto the drive shaft.
Do not use lubricants during the following assembly procedures;
(7) Set the cone on the shaft end and install the flange end first.
(8) Set the cone on the shaft so that there is a gap of 0.8-1.6mm between the
sleeve and the oil slinger. Tighten the locking screw firmly, but do not over-tighten
it.
(9) Use the wooden block to impact the drive shaft in the direction of the crusher
until the pulley sleeve is in contact with the oil slinger, so that the drive shaft
maintains the necessary axial clearance or running clearance.

Figure8 Pulley assembly drawing
1.3 Installation of the eccentric sleeve (partial)
(1) A thin layer of lubricant is applied to the bearing plate and the eccentric sleeve.
(2) Screw the special long eyebolt into the bronze thrust bearing plate and lower it
from the inner hole of the frame to the proper position. Make sure that the lower
plate is convex in the groove of the bottom plate.
(3) A steel upper thrust bearing plate with a press-fit pin on the top is placed
against the bottom of the eccentric sleeve, so that the pin completely enters the
core hole and the thrust plate with the shoulder is located at the center of the
eccentric sleeve. Screw the screw into the thrust bearing plate, but do not extend
the screw beyond the bottom of the thrust plate.
(4) At the other end of the screw, a steel rod is placed on the eccentric sleeve, and
the nut attached to the steel rod is tightened to firmly fix the screw. (See the
eccentric sleeve installation diagram).

(5) Screw the eyebolt screw onto the top of the eccentric sleeve and install the
eccentric sleeve into the crusher.
(6) Make sure that the size gears are properly engaged and that they are in the
correct position. The backlash and headgap of the gear are adjusted according to
the values specified by the flank and the tip clearance. The screw is removed after
the flank clearance and the tip clearance are adjusted to a prescribed range.

5.4 Disassembly and assembly of bowl-shaped bearing bush
Figure15 Bowl-shaped tile disassembly diagram

Figure16 Bowl tile installation diagram
Figure17 Bowl-shaped axe shims installation diagram
Bowl-shaped axe shims installation diagram
Whenever the bowl-shaped bearing frame is attached to the crusher, a gap must be
left between the lower surface of the bowl-shaped bearing frame and the upper
surface of the eccentric large gear. The gap between the bowl-shaped bearing and
the eccentric sleeve of the crusher is 2.38~6.35mm.

Figure18 The gap between the bowl-shaped bearing frame and the eccentric sleeve
When mounting the bowl-shaped bearing frame to the frame, the minimum value
of the lower surface of the bowl-shaped bearing frame and the eccentric sleeve and
the upper surface of the large gear must be carefully checked and carefully
checked.
If this gap is not present, the movement gap between the spindle bushing and the
main shaft will be small when the crusher is running, causing the crusher to
overheat.
After the bowl-shaped bearing frame is installed, if the clearance is small or there is
no gap, remove the bowl-shaped bearing frame and check the gap between the
tooth side and the tooth tip. If the actual value matches the table, the reduction in
clearance between the bowl-shaped bearing frame and the eccentric sleeve may be
due to wear of the support surfaces of the frame and the bowl-shaped bearing
frame. It is recommended to rework the rack or bowl-shaped bearing frame to

repair it to its original size.
A. Disassembly of the bowl-shaped bearing frame
(1) Lift the bowl-shaped bearing frame seal ring to remove the pins, which are
used to prevent the bowl-shaped tile from rotating on the frame.
(2) Use four special hex jacking screws and screw them into the threaded holes
in the bowl-shaped bearing frame.
(3) The rack is evenly heated to 100°F (40°C) above ambient temperature when
the frame is mated with the bowl bearing.
(4) Tighten the jacking screws one by one with a wrench. The bowl-shaped
bearing frame will slowly be ejected from the interference fit of the frame.
(5) Screw the jacking screw a little further until the bowl-shaped bearing frame
separates from the frame.
(6) To prevent corrosion and clogging of dirt, immediately plug the threaded
holes with cotton yarn with grease and grease.
C. General description of bowl tiles
A part of the bowl-shaped tile surface is cut off. Under normal conditions, only
the outer edge is in contact with the body. With the wear of the bowl tile, the main
shaft portion is slowly lowered, so that the running clearance between the main
shaft and the main shaft bushing is reduced. In this case, the self-rotating speed of
the body increases when the crusher is idling. (When the crusher is idling, the
normal body speed should be 0-10 rpm).
Careful inspection of the bowl tile reveals that the bearing surface has worn out

to be flush with the cut. Excessive rotation of the body may also result in insufficient
lubrication and increased oil temperature. It is very likely that the body needs to be
replaced with a bowl-shaped tile when the rotational speed is too high.
When the oil groove of the bowl-shaped tile becomes shallow, its supporting
spherical surface is basically flush with the cut-out portion, and the bowl-shaped
tile must be replaced at this time. Failure to do so may result in damage to the seal
of the bowl-shaped bearing frame and the crusher itself.
D. Replace the bowl tile
When the bowl tile is worn to the extent that it needs to be replaced, the following
steps should be taken:
(1) Lift the bowl-shaped bearing frame seal ring to create conditions for removing
the screws that fasten the bowl-shaped bearing frame and the frame. Screw the
four long special jack-up screws provided as tools into the threaded holes on the
bowl-shaped bearing frame. The frame is evenly heated to 40 ° C above ambient
temperature when the frame is mated with the bowl-shaped bearing frame. Screw
in the jacking screw and the bowl-shaped bearing frame will slowly be ejected from
the interference fit with the frame.
(2) Turn the bowl-shaped bearing frame over the wooden block or other suitable
support as shown in the bowl-shaped tile disassembly diagram. When inverting the
bowl-shaped bearing frame, care should be taken not to obstruct the disassembly
of the bowl-shaped tile.
(3) Place a 4 inch by 4 inch (100 mm x 100 mm) piece of wood on the bowl tile and

tap the block with a sledgehammer. See the bowl tile disassembly diagram. The
bowl tile is tapped around the inner hole at opposite points until the bowl tile is
knocked down.
(4) Then the bowl-shaped bearing frame is coming over and the new bowl-shaped
tile is aligned with the positioning pin on the bearing frame. Replace worn pins if
necessary. These pins prevent the bowl tile from rotating when the bowl tile loses
its interference. The correct amount of profit between the bowl tile and the
bowl-shaped bearing frame is 0.050-0.076 mm.
(5) When there is an interference fit between the bowl-shaped tile and the
bowl-shaped bearing frame, place a wooden block directly on the upper part of the
mating surface of the bowl-shaped tile, and hit the wooden block with a
sledgehammer or hammer, each time the bowl-shaped tile is knocked to its final
position. Come closer. It should be wound around the inner diameter of the bowl
tile at opposite points. See the bowl tile installation diagram.
Do not force the bowl tile with too much force, otherwise the bowl tile will be
upturned or deformed.
(6) After the bowl-shaped tile is in place, pour the babbitt into the pin hole.
(7) After the babbitt has solidified, the excess is scraped off to ensure that there are
no high points. The surface of the Babbitt must be smooth and conform to the
spherical surface of the bowl.
(8) Thoroughly clean and apply a thin layer of lubricant to the surface of the bowl
tile.

1. Disassembly and assembly of dry oil seal:
Figure19 Dry oil seal diagram
(1) Thoroughly clean all parts, remove grease and impurities, and check whether
the oil drain hole around the bowl-shaped bearing frame and the oil groove that
is scooped out are unobstructed. These holes and oil grooves allow excess oil
flowing from the top of the bowl to flow between the bowl and the oil sling and
then return to the crusher. See the dry oil seal diagram.
(2) Check the wear of the dust ring on the body and seal ring.
(3) Check the body and seal ring for damage, gaps, burrs or flash.
(4) Inspect the spring for breakage or failure due to fatigue and replace if

necessary. Use the new spring as a standard to determine if the spring has lost
its elasticity.
(5) Clean the holes in the bowl-shaped bearing frame and the spring sleeve.
(6) Insert the spring into the spring sleeve, apply a thin layer of oil to the sleeve,
and then insert it into the hole in the bowl-shaped bearing frame.
(7) Inspect each spring and sleeve to ensure freedom of movement within the
bore of the bowl-shaped bearing frame.
(8) A stop button is provided on the side of the bowl-shaped bearing frame. See
the stop button diagram. Check that the stop button moves freely in the hole in
the bowl-shaped bearing frame.
(9) Remove the “O” ring (or felt ring and intrude it into the lubricant) from the
inside of the bowl bearing ring seal flange and clean it before inserting it into
the groove.
(10) Align the port on the seal ring with the stop button. Then place the seal
ring above the bowl-shaped bearing frame on the spring sleeve.
(11) Check and make sure that the seal ring on the bowl-shaped bearing frame
is free and free of seals and can move freely on the spring. If the seal ring is "not
free" on the bowl-shaped bearing frame, the inner circle of the felt ring can be
trimmed with a sharp knife.
(12) Remove the lifting eyebolt and fill the threaded hole with cotton yarn filled
with oil or grease.
(13) For dry oil seals, fill the seal ring with lithium-based or equivalent grease

and fill it in the position shown in the dry oil chamber of the bowl-shaped yoke
seal.
(14) Apply a thin layer of lubricant to the surface of the bowl tile and apply
sufficient grease to the seal ring and body ring.
(15) Install the spindle section into the crusher and check that the spring gently
forces the seal ring against the body wiper.
(16) After the spindle is in place, lift it about 13mm and check again if the seal
ring on the spring is free.
5.5 Spindle crushing cone installation
Figure20 Stop button
1. Before installing the crushing cone, a solid and taller wooden shelf should be

placed in the vicinity for the installation of the broken cone.
2. Remove the protective oil layer applied to the shaft and blow the lubricating
oil hole and the oil groove with the wind.
3. Apply a layer of yellow glycerin to the surface of the cone shaft and apply a
thin layer of oil to the ball.
When loading the cone of the crusher, gently insert it into the hollow shaft to
firmly contact the spherical surface with the bowl-shaped bearing of the
bowl-shaped bearing to avoid damage to the spherical ring.
Figure21

Figure22S pindle assembly disassembly diagram

5.6 Installation of lubrication device
1. Lubrication device can be installed according to the assembly drawing designed
by our factory, or it can be configured according to local specific conditions, but the
user-determined configuration drawing and required parts are provided by the
user.
2. Lubrication device configuration must ensure smooth lubrication and oil return.
3. The installation of the lubrication device should be completed when installing
the crushing cone, because the lubrication device should be tested at this time. If
the lubrication is faulty, it is inconvenient to disassemble and repair.
5.7 no-load test
After the above parts are installed, test without load, check whether the installation meets
the requirements, and if it is found to be improper, it is easy to repair.
(1) Check the tightening of the main joint before starting the crusher.
(2) Before starting, turn the crusher by hand to rotate the empty eccentric shaft at
least 2-3 times. It is considered that it can be turned on when there is no jamming.
(3) Before starting the crusher, start the oil pump until the lubrication points are
obtained. After the oil is returned to the tank, the crusher can be started.
(4) The idling test shall be operated continuously for no less than 2 hours.
(5) The crusher idling test must meet the following requirements:
A. The number of revolutions of the broken cone rotating around its own center
line shall not exceed 15 rpm.
B. Bevel gears must not have periodic noise.

C. The lubrication device should meet the following requirements:
a. The pressure on the oil pipe should be in the range of 0.08-0.15 MPa.
b. The return oil temperature must not exceed 50 °C.
c. After the test, the friction parts of the crusher should not be burned and worn.
(6) If the crusher speed may cause a bad phenomenon quickly, it should be
stopped immediately, check and correct, check the oil supply, and then test again.
(7) If the bevel gear has periodic noise, you must check the correctness of the gear
installation and check the gear clearance.

Figure24 Adjustment package
5.8 Installation of adjusting device and adjusting sleeve spring
(1) Clean the support sleeve and the adjusting ring, apply a thin oil
mixture on the serrated thread, and install the locking cylinder. On the
adjusting cap, the interface of the locking cylinder is connected to the
interface of the hydraulic station.
(2) Install the push cylinder accumulator:
The two interfaces M and N of the push cylinder are respectively
connected to M, N of the hydraulic station. The accumulator is clamped
on the feed section by a pipe clamp, and the accumulator interface is
connected to the lock cylinder oil passage through the centering hose
and the cross.

5.9 Installation of the feed port
(1) Improper installation will have the following adverse effects on the crusher:
A. Reduce the output of the crusher.
B. The size of the ore discharge is uneven, and there are many large blocks.
C, the wear parts wear unevenly or accelerate wear.
(2) The height of the feed port from the distribution plate is important for the
normal operation of the crusher. When the feed port is too high, the ore can easily
enter the crushing chamber space without passing through the distributor tray, so
it is necessary to specify an appropriate height for installation.
Figure25 Correction device adjustment sleeve spring installation

The material fed into the crusher is biased to the side of the feed port, causing
uneven feed distribution.

Figure26 Feeding device diagram
5.10 Installation and adjustment test of hydraulic station

(1) For the crusher hydraulic station to be placed in the appropriate position of the
foundation, in order to facilitate operation, the hydraulic station connected to the
main pipe parts and hoses of the main machine, can be properly arranged
according to the actual situation on site.
(2) The three ports of the M.N.P of the hydraulic station are respectively connected
with the M.N port of the pushing cylinder and the P port of the locking cylinder, so
that the two pushing cylinders advance simultaneously or simultaneously.
(3) After the various parts of the hydraulic station are installed, the compression
test is carried out, and the test pressure is 14 MPa.
(4) Locking test
A. Before the lock cylinder is pressed, the accumulator must be flushed with 7.5-8
MPa of nitrogen.
B. Must press the lock cylinder after pushing the cylinder to relieve pressure
C. In the test, the residual gas of the lock cylinder and its pipeline can be removed
through the unloading pipeline or the bottom of the accumulator.
(5) Adjustment test: After the lock cylinder is depressurized, the push cylinder is
used to adjust the discharge opening.
(6) The hydraulic station components are good and flexible.

Figure27 Hydraulic station schematic
5.11 Transmission mode
This type of crusher is driven by a V-belt drive.
The reason why the V-belt drive is particularly suitable is: First, in view of the
characteristics of the belt drive, the impact load of the crusher can be prevented
from being transmitted to the main motor of the crusher; the second can withstand
the pulsation load without causing the speed loss of the crusher.
In order to make the transmission system compact and economical, and reduce the
cantilever load, the design adopts the joint belt which is connected by a single belt
through the connecting layer to prevent the belt from shaking or flipping. The joint
belt is suitable for all standard triangular pulleys. However, the joint belt is limited

to two or three single belts.
FiFigure 28 Belt break diagram
V-belt drive initial installation
Follow the procedure below when installing or reinstalling the V-belt drive for the
first time：
1. Clean the oil, grease and rust in the groove of the V-belt pulley;
2. Make sure the pulleys are aligned and the axes are parallel;
3. Never force the V-belt to hang on the pulley. Usually the center distance is
shortened until the V-belt can be easily placed on the pulley. In order to determine
the minimum range of shortening and lengthening of the pulley center distance,
refer to the V-belt installation and tension gauge;
4. Use a belt that matches the pulley groove and a new belt from the same
manufacturer. Never allow new and old belts to be mixed;
5. After attaching the V-belt to the pulley, let the transmission run for a few
minutes, then tighten the transmission until the transmission is running with only a
slight curvature or sagging on the loose side of the belt. A graphical illustration of

the tight and loose edges is given in "Determining the Pine Edge Map". The loose
side of the belt is determined by two factors: the configuration of the motor and
the steering of the crusher.
Figure29 Relaxation side determination map
5.12 Load test
(1) The load test can only be carried out after the idling test is passed.
(2) The load test shall be carried out continuously for two days and nights (allowing
a short-term parking check).
(3) Add a small amount of ore at the beginning of the load test, and then gradually
increase to full load.

The load test must meet the following requirements:
A. The crusher has no sharp vibration and noise.
B. The normal ore discharge of the crusher is similar to the specified output.
C. The hydraulic station is working normally.
D. The lubrication system meets the following requirements:
a. The oil pressure is 0.08-0.15MPa;
b. The return oil temperature does not exceed 50 °C.
E. There is no damage to the wear parts.
F. Electrical equipment is working properly.

(1) Precautions when working on the crusher:
A. The ore must be given in the middle of the distribution tray (as shown in the
figure). The ore is not allowed to be directly fed into the crushing chamber, because
it is easy to overload the crusher and make the liner wear uneven. The correct
conditions for feeding are:
a. The ore is evenly dispersed in the crushing chamber through the distribution
tray;
b. The ore to be fed should not be higher than the level of the wall.
B. The feeding size of the crusher is not allowed to be equal to the ore size (the
maximum size of the ore block is 85% of the size of the ore). Otherwise it will result
in:

a. The cone crusher production is reduced;
b. Damage to certain parts of the crusher.
C. The crusher is not allowed to start the load, and the load starts to cause an
accident.
D. When stopping, the mining machine must be stopped first, and the ore that has
entered the crushing chamber is broken and discharged, so that the crusher stops.
E. When the crusher is working, the pressure of the locking system and the working
condition of the hydraulic station should be checked frequently, and the problems
should be dealt with in time.
(2) Production of crusher
The output of the crusher is related to the feeding mode, the size of the feed block,
the physical and mechanical properties of the ore, the temperature, etc. The range
of variation is large, and the yield given by the manufacturer is the approximate
calculated value under the specified conditions.
(1) Replacement of rolling wall
The rolling wall is fixed on the adjusting ring with a U-shaped screw, and zinc alloy
or epoxy resin is injected between the two to make it tightly combined. After 6-8
hours of work for newly installing or replacing the rolling wall, it should be checked
tightly. Solidify and tighten the U-screw again.
(2) Gear meshing
Because the friction causes the disc to wear, it affects the change of the gear gap. In
order to ensure the normal meshing of the gear, the gasket must be added to the

bottom cover, and the thickness of the gasket should be equal to the wear of the
circular plate.

5.14 Electrical interlock
The lubrication station control system should have the following electrical interlock
function;

When the oil pressure is lower than 0.028MPa, the crusher motor cannot start;
When the oil temperature is lower than 16 °C, the crusher motor cannot start;
The temperature difference between the oil supply and the return oil shows that
when the temperature difference is greater than 2.8 °C, the sound and light alarm;
Sound and light alarm when the oil return temperature exceeds 54 °C;
When the oil pressure difference between the oil filter before and after the oil
pressure is 0.175MPa, the sound and light alarm;
Light alarm when the system is clogged, the oil pump is faulty or the oil pipe is
broken and the oil flow is interrupted;
Sound and light alarm when the oil level in the fuel tank is lower than 500mm;
When the oil temperature is 21 °C, the electric heater is put into operation by itself;
when the oil temperature is 27 ° C, the resistance heater automatically stops
heating;
When the oil temperature is 50 °C, the air cooler is put into operation by itself;
when the oil temperature is 38 °C, the air cooler automatically stops working.
The starting sequence of the crushing system consisting of the crusher and related
equipment is as follows: first start the oil pump motor, then the mining belt
conveyor, the hoist (if used), the crusher motor, and finally the feeder. The feeder
can only be started after the crusher is running.
The order of system shutdown is the reverse of the order of starting, and the
crusher should be stopped for at least two minutes after stopping the crusher
feeder. If the feeder continues to work after the crusher stops working, it will cause

a mine accident. If the crushing chamber is filled with ore when the crusher is shut
down, it must be cleaned before starting. The crusher cannot be started with load.
At any time, the pump motor must stop before the crusher has stopped.
The control circuit shall be provided with a zero speed switch mounted on the
crusher belt conveyor. In the event that the conveyor stops, the switch will stop the
feeder, which will prevent the crusher from accumulating materials that need to be
shut down for cleaning. When the feeder stops working, an alarm signal is issued,
but the oil pump and crusher will continue to operate.
When using the lubrication station provided by the manufacturer, carefully read the
instructions of the lubrication station before installation. Because the lubrication
station is the supporting equipment of the manufacturer, there are some
precautions not mentioned in this manual in the instructions provided by the
lubrication equipment factory. Electrical control diagrams, etc.
