Jaw crusher application

widely used for mine, smelting, building material, road, railway, irrigation works, chemical and materials with compression strength no more than 320 Mpa.

Jaw crusher consists of bracket, jaw, eccentric shaft, jaw plate and ancon plate etc. Eccentric shaft is driven to rotate by motor and jaw runs on adjusted track to crush materials in crushing chamber.

Jaw crusher working principle

The bracket is welded by steel plate. On the front arm of bracket, jaw plate is fixed by wedge-shaped bolt. Edge protection plate is equipped on inside wall of bracket to prevent abrasion.

The moving jaw is a shaped casting with a kinetic jaw plate on the face. The upper part of jaw is hung on upper and lower parts of bracket and supported on ancon plate by eccentric shaft and roller bearing. There equipped flywheel and grooved pulley at both ends of eccentric shaft.

The other end of ancon plate is supported on adjusting beam. Besides supporting jaw, the ancon plate plays the role of insurance during load increase caused by the uncrushed materials entry into crushing chamber. It will be broken to protect other pieces from damage.

Adjusting beam is welded to side wall of bracket. When the discharge door is adjusted smaller, release tie spring and tightens screw, rotate retention screw to make gasket up, insert new gasket to achieve required size of discharge door, turn back retention screw to make jaw press closely the gaskets, rotate nut staybolt and fix it and at last, rotate tie spring tight. Conversely, from small size to large one (draw gasket out).
