MARSMAN : Secondary Jaw Crushers are ideally suited for crushing of hard granite stone,  black tarp rock, river gravel, lime stone, coal, iron, ore etc.

BODY : The body is made form tested M.S. Plates. It is fabricated with horizontal and vertical ribs for strength and sturdiness, the body is annealed & stress released by heat treatment process to reduce the chance of the body getting cracked.

SWINGING LEVER : The swinging lever (pitman) is fabricated out of M.S. Plates with high tensile strength and it is annealed by heat treatment process and then it is precision machined for smooth crushing stroke.

TOGGLE PLATES & TOGGLE BEARINGS : For equal balance and load distribution the crank shaft is centrally fitted on cast steel  toggle bearings. The cast steel toggle bearings withstand excessive wear & tear and convey correct crushing
stroke.

JAW PLATES & SIDE PLATES : The jaw plates are made of high tensil manganese steel.  Specially designed teeth of Jaw plates are suitable to  produce cubical shape material as per required output sizes.  One jaw is fixed and the other jaw is fitted on swinging lever.  He side plates are of close  fitting type which prevent any wear to the body, which is made out of high grade manganese steel.

CRANK SHAFT & BEARING : The crank shaft is made of forged steel and fitted in heavy duty spherical double roller bearings which ensures smooth  operation.  The bearings are fitted on both sides of the crank shaft and two in swinging lever, which are well sealed against possible entry o dust and moisture by labyrinth seals. For lubrications grease nipples are fitted at appropriate places.

FLYWHEELS : Heavy duty cast iron flywheels are fitted on both the ends of crank shaft. These flywheels are machined all over, counter weight fitted and balance to ensure steady crushing force.

WARRANTY :  MARSMAN  Jaw Crushers are warranted for ONE YEAR  against manufacturing defects. However, the warranty does not cover breakdowns under normal wear & tear due to  misuse / mistake made by operator.
