Product Description
PE Coarse Jaw Crusher Application:
The crusher can be used to crush ores and rocks whose grain size is smaller than 340mm. It can be widely used in small and medium mine, building material, highway engineering, silicate and chemical industry. Coarse jaw crusher can crush the materials whose compressive strength is less than 320MPa.

Coarse jaw crusher Working Principle:
The electric motor transmits power through belt, drives the moving jaw plate do periodic movement to the fixed jaw plate surround the eccentric shaft. The angle between toggle plate and moving jaw plate enlarges when the moving jaw plate moves up. So the moving jaw plate is closes to the fixed jaw plate. The stuff will be crushed in this process. The angle between toggle plate and moving jaw plate decreases when the moving jaw plate moves down. The moving jaw plate moves away from fixed jaw plate by the pulling of rod and spring. The products such as stone after be crushed will be discharged from the outlet.
Features of Coarse jaw crusher:
1\Large crushing rati: Up to 10-15; Allow some of the largest feed up to 400mm, the minimum discharge can to 20mm, which combines a thick broken secondary crushing crushing double function;
2\Even granularity: The same process, the ratio of normal jaw broken as PEX150 × 700 reduced 40-50%, P80 up to 10mm below
3\Simple structure;
4\Reliable operation;
5\Easy maintenance;
6\Low expense: The same process, the ratio of normal jaw broken as PEX150 × 700 reduced 40-50%, P80 up to 10mm below.
