Secondary Jaw Crushers
Application
MARSMAN* Secondary Jaw Crushers are ideally suited for crushing of hard granite stone, black tarp rock, river gravel, lime stone, coal, iron, ore etc.
SALIENT FEATURES
- 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.
- FLY WHEELS : 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.
You Should Know
The Output in tons indicated above is on average hard dry quartz weighing at least 1.6 Tons /m3 when crushed and on continuous feed of graded sizes with fines removed.
Capacities may vary by 25 % depending on type of rock, gradation and method of feeding.
Where no capacity rating is given in the table, it is generally not economical to operate at such setting.
- 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.
- 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.
