Grinder Jaw Crushers are used to process medium-hard, hard, brittle and tough sample fast and gently. The Jaw plates have 6 kinds of material to choose.This series of products with superior technical and safety performance, so it is your ideal choice in the laboratory and enterprise production for the sample preparation.
 
Work principle
The sample enters the grinding chamber via the anti-splashing hopper. The crushing is proceeded inside the wedge-shaped shaft space between two jaw plates. one jaw plate is fixed, while the other jaw plate is driven by a bent axle to perform oval movement with the continuous rotation of the motor. The sample is crushed due to extrusion caused by constant movements of the jaw plate and moves downward under the effect of gravity. In case the grain size of the sample is less than the lower opening gap of jaw plates, it will fall to the drawer receiver at the lower part of the machine.
