Apron Feeders
Introduction
Apron Feeder is a mechanical equipment widely used in Bulk
material Handling. Its application is found in almost all sectors
like power, steel, cement plant, etc.
The Apron Feeders are broadly classified as
a) Extra heavy duty Apron Feeder with crawler chain-sprocket
assembly.
b) Extra heavy duty Apron Feeder with link-chain assembly.
c) Heavy duty Apron Feeder with link-chain assembly.
The Apron Feeder consists of one or more endless chains to
which overlapping pans are attached to form a continuous
moving bed particularly suited for conveying heavy duty raw
materials such as coal, coke , ore, slag, rock, stone, gravel, clay,
etc. They are frequently used as feeders located under crushers
and hoppers. Apron Feeders can be installed in horizontal and
inclined condition depending on the feeding zone of system
layout.
It is recommended that for higher conveying efficiency, the
feeder’s inclination should be within 10 degrees.
It’s use lends itself to situation where a belt conveyor is not
suitable i.e., for hot materials and large material lumps. Pan
width is normally selected in between 700 mm. to 3000 mm.
depending on material, feed size and capacity.
Apron Pan, chain, rollers and other components are of robust as
they have to take direct feed and withstand free dropping
materials from an appreciable height on to the Apron Pan.
It is recommended that Apron Feeders operate at lowest
possible speed to avoid early wear of machine parts. The speed
normally depends on bulk-density of material and lump size.
The Extra Heavy-Duty Apron Feeder can be installed at the
discharge section of dump truck or storage bin which receives
strong falling impact load, raw material pressure and lumps
upto 2000 mm.
TRF extra heavy-duty type Apron Feeder is so rationally and
strongly designed and manufactured that it can be operated in a
stable manner even under severe conditions.
Specification of each part
(1) Apron Pan and Conveyor Chain
The Apron Pan is made of steel plate and has sufficiently
high strength to falling impact load of large lumps. The
material of apron may be wear-resistant steel plate or high
manganese cast steel.
The Conveyor Chain is a high precision link chain or
crawler chain with special shape having enough strength
and life. It is fitted with Apron Pan, either at bottom or side.
(2) Feed
The Feed Roller can withstand falling impact load through
Apron and is arranged at regular intervals to ensure
smooth running of the Apron. Roller surface has wear
resistibility, and sealed bearing is used for bearing part.
(3) Driving machine
The driving machine is composed of sprocket wheel and
tail wheel for conveyor chain, head shaft, tail shaft, take-up
device, plummer blocks with bearing and safety covers.
Driving method is to drive head shaft by variable speed
motor through reducing speed by reducer. Cast steel
plummer block with self-aligning roller bearing is used.
Hydraulic drive is also used in some cases.
(4) Frame, Hopper, Skirt, Chute
Each part is made by welding of shape steel and steel plate
and so strongly constricted that it can sufficiently
withstand falling impact load of feed material or hopper
pressure.
Exchangeable liner of wear resistant steel is provided
inside hopper and skirt. Liners like Arco, Hardox, Hadfield,
Sailhard, etc. are used.
(5) Lubricating device
Lubricating of each bearing of Plummer block is effected by
the hand pump from one place or by the centralized
forced lubricating system consisting of many distributing
valves.
(6) Overload safety device
In case excessive load or overload is placed, motor and
machine are protected by overcurrent relay.
Setting of overload time and detection point can be
adjusted arbitrarily.

Apron Feeders
Introduction
Apron Feeder is a mechanical equipment widely used in Bulk
material Handling. Its application is found in almost all sectors
like power, steel, cement plant, etc.
The Apron Feeders are broadly classified as
a) Extra heavy duty Apron Feeder with crawler chain-sprocket
assembly.
b) Extra heavy duty Apron Feeder with link-chain assembly.
c) Heavy duty Apron Feeder with link-chain assembly.
The Apron Feeder consists of one or more endless chains to
which overlapping pans are attached to form a continuous
moving bed particularly suited for conveying heavy duty raw
materials such as coal, coke , ore, slag, rock, stone, gravel, clay,
etc. They are frequently used as feeders located under crushers
and hoppers. Apron Feeders can be installed in horizontal and
inclined condition depending on the feeding zone of system
layout.
It is recommended that for higher conveying efficiency, the
feeder’s inclination should be within 10 degrees.
It’s use lends itself to situation where a belt conveyor is not
suitable i.e., for hot materials and large material lumps. Pan
width is normally selected in between 700 mm. to 3000 mm.
depending on material, feed size and capacity.
Apron Pan, chain, rollers and other components are of robust as
they have to take direct feed and withstand free dropping
materials from an appreciable height on to the Apron Pan.
It is recommended that Apron Feeders operate at lowest
possible speed to avoid early wear of machine parts. The speed
normally depends on bulk-density of material and lump size.
The Extra Heavy-Duty Apron Feeder can be installed at the
discharge section of dump truck or storage bin which receives
strong falling impact load, raw material pressure and lumps
upto 2000 mm.
TRF extra heavy-duty type Apron Feeder is so rationally and
strongly designed and manufactured that it can be operated in a
stable manner even under severe conditions.
Specification of each part
(1) Apron Pan and Conveyor Chain
The Apron Pan is made of steel plate and has sufficiently
high strength to falling impact load of large lumps. The
material of apron may be wear-resistant steel plate or high
manganese cast steel.
The Conveyor Chain is a high precision link chain or
crawler chain with special shape having enough strength
and life. It is fitted with Apron Pan, either at bottom or side.
(2) Feed
The Feed Roller can withstand falling impact load through
Apron and is arranged at regular intervals to ensure
smooth running of the Apron. Roller surface has wear
resistibility, and sealed bearing is used for bearing part.
(3) Driving machine
The driving machine is composed of sprocket wheel and
tail wheel for conveyor chain, head shaft, tail shaft, take-up
device, plummer blocks with bearing and safety covers.
Driving method is to drive head shaft by variable speed
motor through reducing speed by reducer. Cast steel
plummer block with self-aligning roller bearing is used.
Hydraulic drive is also used in some cases.
(4) Frame, Hopper, Skirt, Chute
Each part is made by welding of shape steel and steel plate
and so strongly constricted that it can sufficiently
withstand falling impact load of feed material or hopper
pressure.
Exchangeable liner of wear resistant steel is provided
inside hopper and skirt. Liners like Arco, Hardox, Hadfield,
Sailhard, etc. are used.
(5) Lubricating device
Lubricating of each bearing of Plummer block is effected by
the hand pump from one place or by the centralized
forced lubricating system consisting of many distributing
valves.
(6) Overload safety device
In case excessive load or overload is placed, motor and
machine are protected by overcurrent relay.
Setting of overload time and detection point can be
adjusted arbitrarily.

Travelling Wagon Loaders
Loading of bulk materials in steel, power & mining industries
Travelling Wagon Loaders are essential equipment for loading bulk
material into railway wagons at high speed. Wagon Loaders
supplied by TRF can load up too 3000 tonnes per hour.
TRF wagon loading systems are so designed that there is no spillage
between the wagons when the loader is traveling from one end of the
rake to the other. Filling efficiencies up to 99 percent of the desired
capacity have been achieved.
A Travelling Wagon Loaders manufactured at TRF comprises :
The tripper conveyor
Intermediate conveyor with belt weigher
Cross conveyor with loading chutes
TRF has supplied Travelling Wagon Loaders for loading bulk cargo
like coal, coke, limestone and iron ore. TRF’s travelling wagon
loaders can load rakes placed on both sides of the track in a 2 x 2
formation. The cross conveyor shuttles out while loading into rakes
at the farther end. All controls are through PLC .The travel speed of
the wagon loader is synchronized automatically to complete the
loading of one wagon and then travel rapidly to the second wagon to
minimize detention time of the rake. Facilities on board include
checking of loading rate and totalizers on shift, day,
=
=
=
and month basis. TRF Travelling Wagon Loaders are designed to
automatically identify sick wagons in the rake and bypass these
wagons while completing the loading of the full rake.
The material feeding into the wagons is kept uniform by use of TRF
designed belt weigher over the cross conveyor. The feeder is
synchronized with the loading rate and can be programmed to feed
at any desired rate up to its maximum capacity.
The operator's cabins are so located that the operator gets a clear
and unobstructed view of the loading process. The cabin is air-
conditioned and ergonomically designed for maximum comfort of
the operator. The front screen is mounted in the operator's console
and displays details of all operations enabling the operator to
program according to the loading requirement.
The air-conditioned electric house is equipped with online fault
display and analysis tool to minimize downtime. Hydraulic rail
clamps, storm anchor and air conditioned electric room, dust
suppression system, radio control and fire alarm are also provided,
if required by the customers.
TRF’s wagon loaders are provided with pneumatically PLC
controlled sector gates to avoid choking of material.

Travelling Wagon Loaders
Loading of bulk materials in steel, power & mining industries
Travelling Wagon Loaders are essential equipment for loading bulk
material into railway wagons at high speed. Wagon Loaders
supplied by TRF can load up too 3000 tonnes per hour.
TRF wagon loading systems are so designed that there is no spillage
between the wagons when the loader is traveling from one end of the
rake to the other. Filling efficiencies up to 99 percent of the desired
capacity have been achieved.
A Travelling Wagon Loaders manufactured at TRF comprises :
The tripper conveyor
Intermediate conveyor with belt weigher
Cross conveyor with loading chutes
TRF has supplied Travelling Wagon Loaders for loading bulk cargo
like coal, coke, limestone and iron ore. TRF’s travelling wagon
loaders can load rakes placed on both sides of the track in a 2 x 2
formation. The cross conveyor shuttles out while loading into rakes
at the farther end. All controls are through PLC .The travel speed of
the wagon loader is synchronized automatically to complete the
loading of one wagon and then travel rapidly to the second wagon to
minimize detention time of the rake. Facilities on board include
checking of loading rate and totalizers on shift, day,

and month basis. TRF Travelling Wagon Loaders are designed to
automatically identify sick wagons in the rake and bypass these
wagons while completing the loading of the full rake.
The material feeding into the wagons is kept uniform by use of TRF
designed belt weigher over the cross conveyor. The feeder is
synchronized with the loading rate and can be programmed to feed
at any desired rate up to its maximum capacity.
The operator's cabins are so located that the operator gets a clear
and unobstructed view of the loading process. The cabin is air-
conditioned and ergonomically designed for maximum comfort of
the operator. The front screen is mounted in the operator's console
and displays details of all operations enabling the operator to
program according to the loading requirement.
The air-conditioned electric house is equipped with online fault
display and analysis tool to minimize downtime. Hydraulic rail
clamps, storm anchor and air conditioned electric room, dust
suppression system, radio control and fire alarm are also provided,
if required by the customers.
TRF’s wagon loaders are provided with pneumatically PLC
controlled sector gates to avoid choking of material.

Double Roll Crushers
Description and Uses
Two rolls rotate in opposite directions in this
crusher. The material is fed between the two
rolls for compressive action and breaking into
fragments of uniform size. Simplicity of
mechanical construction and ease of
operation are the two highlights of this
crusher. The amount of fines generated from
crushing is relatively small, a performance
feature which qualifies this machine for use in
the following installations:
The Double Roll Crusher is available
with heavy duty rolls for crushing such
hard materials as ore or with light duty
rolls for crushing relatively soft materials.
each roll assembly consist of a roll boss with
hexagonal outer shape rigidly mounted on
the roll shaft which permits easy replacemant
of roll tyre. The roll tyres are held tight by
means of bolts. This arrangement provides
for easy tyre replacement and minimizes
parts subject to wear. The roll tyres are made
of high manganese steel.
(3) Bearings
Spherical roller bearings are used to
support the rolls. The spherical roller
bearings are complete with labyrinth
seals and packings for preventing
entrance of dust and leakage of oil.
(4) Drive
The standard Double roll crusher has
independent belt drives from two
motors, one motor for each roll. This
arrangement eliminates the need for an
intermediate drive transmitting device
resulting in less space utilisation and
reducing the no-load power loss.
(1) Frame
A cast-iron or steel-plate frame is used.
The steel-plate frame is fabricated by
welding. The plummer blocks of fixed roll
assembly are integral with the frame.
The Plummer Block for the movable roll
assembly are elastically positioned in
horizontal direction with high-strength
coil springs or hydraulic accumulators
selected for the type of crushing duty.
This elastic mounting includes a means
of adjusting the roll-to-roll clearance (roll
setting) and serves as a protective
feature for preventing motor over load or
damage to the crusher, as the roll will
yield and back away when it grips hard
foreign matters like tramp iron.
(2) Rolls
Roll tyres are of smooth type, corrugated
type or toothed type, depending on the
crushing duty. In the standard design

Roller Screens
Description
Application :
Construction :
Roller screens consists of a rigid main frame and a series of
roller disc assemblies mounted on shafts and supported on
spherical roller bearings across the width of main frame. These
roller discs are elliptical in shape and arranged at a pre-
determined distance in such a way that they form a square or
rectangular opening in the roller screen at several places. Over
sized materials are pushed forward by rotation of elliptical
discs and finally reach the crusher as feed, while undersized
material falls through the screen opening. The scrapper
provided below the elliptical discs ensures clog free screening.
These roller shaft assemblies are driven by chain and sprocket
arrangement. All roller shaft assemblies are connected
alternately with chain and sprocket and are driven in same
direction by two drive units. Drive is fully covered and operates
in a circulating oil bath.
Each roller screen has two drive units along with electric motor,
fluid coupling, gearbox and drive sprocket.
TRF Roller screens are most suitable for separating coars
wet and sticky raw material. Roller screens are used in soft coal,
and lignite handling plants for preliminary screening of ROM
coal. It acts as relief to crushers and ensures a clog free flow of
wet and sticky materials. TRF roller screens are useful for
separation of undersized material ranging from (-) 20 mm. to (-)
60 mm. The roller screens can be placed horizontally or at
angle of maximum 10 degrees.
The roller screens consist of a rigid frame on which a series of
roller shaft assemblies are mounted with anti-friction bearings

Hydraulic Cone Crusher
TRF’s Hydraulic Cone Crushers which apply a unique
hydraulic control system are used in secondary and
tertiary crushing.
Main characteristics of the hydraulic cone crusher are to
support the crushing head (mantle and mantle core)
through the centre shaft from the bottom by hydraulic
cylinder and to adjust the discharge setting between
mantle and bowl liner automatically and remotely by
changing oil quantity in the hydraulic cylinder. This
equipment consists of hydraulic cylinder provided at the
lower part of frame, hydraulic unit connected with
hydraulic cylinder by high pressure piping and control
panel attachable to the optional place such as machine-
side of operation room.
Crushing capacity has been increased and cubical
product having excellent cubic type can be obtained as
the unique mechanism is adopted and designed for the
best crushing chamber and large throw of mantle. Choke-
feed is possible resulting in the increment of crushing
capacity and the improvement of the shape of crushed
product.
Raw materials are evenly fed to the whole circumference
of crushing chamber by means of feed plate installed on
the upper portions head. Even feeding can be ensured
without any hindrance as spinder arm does not exist. Thus
partial abrasion of bowl liner will not occur. Therefore,
special distribution feeder is not necessary.
When mantle of crusher moves up and down, selsyn
transmitter provided at the lower part of hydraulic cylinder
transmits the degree of movement to selsyn receiver of
control panel and automatically shows it on discharge
setting indicator.
When changing discharge opening, mantle freely goes up
and down as hydraulic pump acts for upward control an
electro-magnetic valve acts for downward control by the
operation of setting control switch while looking at
discharge setting indicator. Therefore, automatic setting
adjustment is possible more easily, quickly and
accurately than hydraulic clamping and resetting device
of the coventional symons type crusher. The adjustment
of discharge setting is possible either at the time of
machine stoppage, no load operation, or load operation.
Characteristics
High Capacity
Partial abrasion of bowl liner will not occur
Easiness of adjustment of discharge setting
SECTIONAL ARRANGEMENT
The abrasion loss of mantle and bowl liner is
indicated
In case of foreign matter entering, safe
operation is possible
In case the machine stops during operation
due to the electric failure etc., discharge is
possible
As the abrasion loss of mantle and bowl liner is indicated on
the dial of control box, the correction of discharge setting is
easy and the time to arrange spare part can be predicted.
Even when uncrushable such as tramp iron has entered, it is
discharged outside the machine by the hydraulically
controlled automatic discharge mechanism.
Even if the machine stops during operation under load due to
electric failure etc., raw material in crushing chamber can be
discharged by moving crushing head up and down with
hydraulic mechanism before restarting at the current
retransmission. Therefore, the operation can be resumed in
a short time.
Easy replacement of mantle and bowl liner
When replacing consumable parts such as mantle and bowl
liner, the replacement can be carried out easily in short time
as bearing and spider arm do not exist in the upper part of
crushing chamber.
Features :
= Simple and Rigid construction
= Speedy installation with special hydraulic system
= High mobility on standard trailer
= Cost saving for foundation work

Hydraulic Cone Crusher
TRF’s Hydraulic Cone Crushers which apply a unique
hydraulic control system are used in secondary and
tertiary crushing.
Main characteristics of the hydraulic cone crusher are to
support the crushing head (mantle and mantle core)
through the centre shaft from the bottom by hydraulic
cylinder and to adjust the discharge setting between
mantle and bowl liner automatically and remotely by
changing oil quantity in the hydraulic cylinder. This
equipment consists of hydraulic cylinder provided at the
lower part of frame, hydraulic unit connected with
hydraulic cylinder by high pressure piping and control
panel attachable to the optional place such as machine-
side of operation room.
Crushing capacity has been increased and cubical
product having excellent cubic type can be obtained as
the unique mechanism is adopted and designed for the
best crushing chamber and large throw of mantle. Choke-
feed is possible resulting in the increment of crushing
capacity and the improvement of the shape of crushed
product.
Raw materials are evenly fed to the whole circumference
of crushing chamber by means of feed plate installed on
the upper portions head. Even feeding can be ensured
without any hindrance as spinder arm does not exist. Thus
partial abrasion of bowl liner will not occur. Therefore,
special distribution feeder is not necessary.
When mantle of crusher moves up and down, selsyn
transmitter provided at the lower part of hydraulic cylinder
transmits the degree of movement to selsyn receiver of
control panel and automatically shows it on discharge
setting indicator.
When changing discharge opening, mantle freely goes up
and down as hydraulic pump acts for upward control an
electro-magnetic valve acts for downward control by the
operation of setting control switch while looking at
discharge setting indicator. Therefore, automatic setting
adjustment is possible more easily, quickly and
accurately than hydraulic clamping and resetting device
of the coventional symons type crusher. The adjustment
of discharge setting is possible either at the time of
machine stoppage, no load operation, or load operation.
Characteristics
High Capacity
Partial abrasion of bowl liner will not occur
Easiness of adjustment of discharge setting
SECTIONAL ARRANGEMENT
The abrasion loss of mantle and bowl liner is
indicated
In case of foreign matter entering, safe
operation is possible
In case the machine stops during operation
due to the electric failure etc., discharge is
possible
As the abrasion loss of mantle and bowl liner is indicated on
the dial of control box, the correction of discharge setting is
easy and the time to arrange spare part can be predicted.
Even when uncrushable such as tramp iron has entered, it is
discharged outside the machine by the hydraulically
controlled automatic discharge mechanism.
Even if the machine stops during operation under load due to
electric failure etc., raw material in crushing chamber can be
discharged by moving crushing head up and down with
hydraulic mechanism before restarting at the current
retransmission. Therefore, the operation can be resumed in
a short time.
Easy replacement of mantle and bowl liner
When replacing consumable parts such as mantle and bowl
liner, the replacement can be carried out easily in short time
as bearing and spider arm do not exist in the upper part of
crushing chamber.
Features :
= Simple and Rigid construction
= Speedy installation with special hydraulic system
= High mobility on standard trailer
= Cost saving for foundation work
