1/1

The lump Breaker is fixed in the line of Chain Conveyor used in blasting Gallery minto crush / reduce the large lumps of R O M Coal.

The equipment is of rigid and stable construction mounted on chain conveyor line pof 1.5 M long and size of 640 x 190 mm.

When the material is conveyed through the Chain Conveyor, the large lumps entebetween deck plate of line pan and crusher rolls get crushed by the breaker wheerequired size by impact of picks mounted to the wheel.

The Helical/Bevel gear box has been specially designed to suit the Undergrouconditions and to withstand shock loads. Proper Lubrication and dust free enclosuensure smooth and noiseless running.

The chain conveyors are of robust design with compact construction comprising of components which areamply proportioned to meet severe conditions encountered in such services. The construction is modularand addition of troughs can be easily carried out.

The design of Drive head is robust and sturdy to withstand impact of coal lumps.

High quality chains are provided for longer life of machine and to withstand shock loads during working.

Sprocket and tail end drum are made out of cast steel suitably treated.Pinions, gears and shafts are made of high strength materials and properly heat treated. The gear boxesare conveniently mounted to facilitate maintenance.

Wear resistance plates (Manganese Steel) are provided in the troughs.

Flights made out of high quality forged steel.

Spill plates on either side of the troughs are provided as per requirement.

Tail end drum is mounted on anti friction spherical roller bearings. Longitudinal slots are provided to slidethe drum axle to maintain required tension in chains. The tensioning is achieved by adjusting the screw.

Motor is suitable for operation in humid and dust laden atmosphere of underground coal mines.
