Primary Jaw Crusher - High Tensile Manganese Steel Body, Forged Steel Crank Shaft , Precision Engineered Swinging Lever

Marsman Primary Jaw Crushers are ideally suited for crushing of hard granite stone, black trap rock, river gravel, lime stone coal, iron etc. at primary stage with maximum output capacity.

Body : The body is made from tested M.S. Plates. It is fabricated with horizontal and vertical ribs for strengths and sturdiness, the body is annealed & stress relieved 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 and tear and convey correct crushing stroke.

Jaw plates & side plates : The Jaw plates are made of high tensile manganese steel. One jaw is fixed and the other Jaw is fitted on swinging lever. The 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.
