Jaw crushers are ideal for primary and secondary crushing.Jaw crusher also called as stone jaw crusher. It is ideally suitable for crushing all kinds of ores and crushing the big size materials, the highest anti-pressure strength of crushed material is 320 MPA, having two types: primary crushing and secondary crushing.
There are some advantages about jaw crusher used as stone crusher, they are as follows:
Heat treated shafts forged of special alloy to handle overloads and hard materials.
Heavy duty self aligned spherical roller bearings absorbs and withstand extreme shock, radial and thrust load and offer substantially more bearing life.
Much heavier, stronger, massive one piece frame, stress- relived for optimum reliability.
Toggle bearing wedges for easy in, easy out bearing replacement.
Hardened barrel wear lines (Side plate) protect the pitman (Lever).
Replaceable Fix & swing jaw plate made out high chrome & manganese percentage.
One piece cast pitman (Lever) stands up to the most demanding crushing applications.
Larger stroke, deeper crushing motion, steeper nip angle means higher capacity and greater throughput
How does the jaw crusher broke the raw materials?
Motor drives belt and belt pulley, makes moving jaw up and down through eccentric shaft. When the moving jaw is up, the angle between lining plate and moving jaw becomes large, and this will push moving jaw plate close to the fixed jaw plate. During this process, the material is crushed and ground, thus the crushing will be done. When the moving jaw is down, the angle between lining plate and moving jaw becomes small, the moving jaw plate will leave the fixed jaw plate on account of the effect of pulling bar and spring, and then the crushed material will be discharged from the lower opening of the crushing room. With the motor continuously rotating and the material periodically crushed and discharged by the crusher, the mass production can be realized.
With the increase of production, DSMAC jaw crusher can greatly reduce the operating costs. The large feed opening and force-feeding action from the inward and downward eccentric movement of the swing jaw mean that our jaw crusher can increase the capacity. The jaw has a smaller discharge setting, allowing for a higher degree of flexibility with relative equipment. Positive setting adjustment is easy. The jaw crusher is the best choice for crushing various materials.
