Double Roll Crushers
Description and UsesTwo rolls rotate in opposite directions in thiscrusher. The material is fed between the tworolls for compressive action and breaking intofragments of uniform size. Simplicity ofmechanical construction and ease ofoperation are the two highlights of thiscrusher. The amount of fines generated fromcrushing is relatively small, a performancefeature which qualifies this machine for use inthe following installations:
The Double Roll Crusher is availablewith heavy duty rolls for crushing suchhard materials as ore or with light dutyrolls 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) FrameA cast-iron or steel-plate frame is used.The steel-plate frame is fabricated bywelding. The plummer blocks of fixed rollassembly are integral with the frame.The Plummer Block for the movable rollassembly are elastically positioned inhorizontal direction with high-strengthcoil springs or hydraulic accumulatorsselected for the type of crushing duty.This elastic mounting includes a meansof adjusting the roll-to-roll clearance (rollsetting) and serves as a protectivefeature for preventing motor over load ordamage to the crusher, as the roll willyield and back away when it grips hard
foreign matters like tramp iron.
(2) RollsRoll tyres are of smooth type, corrugatedtype or toothed type, depending on thecrushing 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
