The production capacity of the crusher is affected by many factors, such as the feed
stock’s nature, shape, particle size, feeding mode, working conditions,
etc.Limestone is easy to break, while hard, spherical materials are not easy to be
broken, which naturally reduces the processing capacity; large materials tend to
block the feed port; Feedstocks of different size can achieve higher production
capacity than uniform size feedstocks; the mixing of the material into the mud will
also reduce the production capacity of the equipment; the performance parameters
of the machine calibration are based on the broken medium hardness rock.
3. Structure brief
This machine is mainly composed of parts such as frame, moving jaw, eccentric
shaft, tooth plate, bracket, adjusting seat and so on. (As shown in figure 1). The
motor drives the eccentric shaft through the pulley through the V-belt to
reciprocate the movable jaw. Thereby, the material entering the crushing chamber
is broken, and the material is discharged from the discharging port after the
crushing.
The frame is a single integral cast steel structure, the front wall is equipped with a
fixed tooth plate fastened with wedges, the left and right side walls of the crusher

frame are provided with guard panels to prevent the side wall from being worn out.
The movable jaw is a shaped casting structure is provided on the face of the
movable tooth plate, the upper part of the eccentric shaft and self-aligning bearing
hanging on the rack, the lower support plate in the elbow, and rolling contact with
the bracket.
The moving jaw is a formed steel casting structure,the front side is equipped with a
movable jaw plate,the upper part is suspended from the frame by an eccentric shaft
and a self-aligning bearing, the lower part is supported on the bracket and is in
rolling contact with the bracket.
The other end of the bracket is supported on the adjustment seat and is in rolling
contact therewith, in addition to supporting the moving jaw, the bracket is
operated according to a certain movement trajectory, in the case where a foreign
object that cannot be broken from the outside enters the crushing chamber and a
load surge occurs,It acts as an insurance, that is, it breaks rapidly, cuts off the load,
and protects other parts from damage.
The adjustment seat is fixed on the ear seat on both sides of the rack, adjusting the
wedge locking structure at both ends of the bottom of the adjusting seat, rotate
the adjusting bolt to open the adjustment seat, change the width of the gasket to
adjust the width of the discharge opening, Thereby obtaining the desired product
particle size.
The tension spring device is used to ensure that the moving jaw, the bracket and
the adjusting seat are closely coupled with each other, make the crusher operate

normally, the spring pressure should not be too large when the crusher is working,
as long as it can eliminate the impact sound between the bracket and the moving
jaw and the adjusting seat.

The eccentric shaft is made of high quality and high strength forged steel，after
many precision machining, heat treatment and flaw detection, therefore, it has
enough strength and toughness.
Both ends of the eccentric shaft are respectively provided with a sheave and a
Flywheel.It is mounted on the eccentric shaft by tapping or pressure, and is tight
against the inner ring (end cap seal).The mark on the Flywheel（sheave) corresponds
to the mark on the eccentric shaft, and the position of the eccentric block cannot
be misplaced (See Figure 2).The expansion sleeve is installed as shown in Figure 2.
After being placed, the bolts on the expansion sleeve are evenly tightened, and the
tightening force of each bolt is 190N.
Note: The Flywheel（sheave) is cast iron, do not Violent knock when installing. The
sheave is conventionally mounted on the left end of the machine (as seen from the
feeding direction), and the position of the Flywheel （ sheave) can be reversed
according to the site conditions.

4. Installation & adjustment
The jaw crusher is assembled into a whole from the factory, users should check
carefully when receiving it in order to identify and eliminate problems that may
occur during transportation.
Since the crusher has a large vibration during operation, it is recommended to
install the machine on a concrete foundation and put the cushioning material such
as hardwood or rubber.
The weight of the foundation is roughly 5-10 times the weight of the machine, the
depth of the foundation depends on the geological conditions.The base drawing
supplied by the factory only provides anchor bolt position for foundation
construction, user should design the basic construction drawing according to the
specific conditions of the installation site.
3. The basic discharge trough should be laid with a layer of steel plate and have
sufficient inclination angle to avoid blocking.
4. When adjusting the discharge opening, the tension spring should be opened first,
the bolts should be tightened, and the locking wedges at both ends of the bottom
of the seat should be adjusted, use the adjusting bolt to open the adjusting seat
and insert or remove the adjusting gasket of the corresponding thickness (see
Figure 3). then, the adjusting bolt is returned, and the adjusting seat is pressed
together under the action of the weight of the moving jaw.
5. Refer to Figure 4 for electrical wiring.
