The working principle of jaw crusher is very simple. The whole crushing process rely on the relative motion of the two jaw plates. One of the jaw plates stay still while the other move against it. And with the movement, the materials between the two plates would be crushed into small elements. While the plates move against each other, the materials would be crushed and while plates move away from each other, the broken materials which are smaller enough would drop through the discharging opening. And due to the simple structure, jaw crusher is easy to maintain and repair. These features promote its popularity to a great extant.

working principle of heavy machinery jaw crusher

This series mining diesel engine mini stone crusher price adopts electric motor as the power, and the eccentric shaft is revolved by an electric motor through v-belts. It causes the swing jaw to follow the pre concerted path and crush the in-fed materials, and then the materials will be crushed in the crushing chamber which is composed of the stationary jaw plate, swing jaw plate and the liner plate. Finally the finished materials are discharged from the lower part of machine.

Please carefully examine the fasteners, especially the lubrication components and bolts before starting the machine. Enough oil is needed on each lubrication component. Fasten the loose bolts, clean the crushing cavity, and then start the machine. Insufficient load or over load is not allowed. Moving jaw plate, fixed jaw plate, side guard plate and roof plate are wearing parts, and much attention should be paid to them.
