Product Introduction

PEX Jaw crusher is a large composite pendulum type widely applied in various industries such as mining, metallurgy, construction, highway, railway, water resources and chemical industries for primary or secondary crushing of ores and rocks with large granularity and compressive strength of no more than 320Mpa. It is populated by consumers for its simple structure, stable performance, low cost and and big size reduction ratio.

Jaw Crusher Structure

Structure

PEX Jaw crusher is mainly consisted of the frame, eccentric shaft, big belt pulley, flywheel, moving jaw, side guard plate, toggle plate, toggle plate backseat, space adjusting screw, retracting spring, fixed jaw plate and moving jaw plate. The toggle plate plays the role of insurance.

Working Principle

Driven by the motor, PEX jaw crusher makes the moving jaw reciprocate in a given trail by eccentric shaft driven by V-belt, belt wheel and sheave, thus, materials in the crushing chamber made up of fixed jaw plate, moving jaw plate and the side canopy can be crushed and discharged from the lower discharging outlet. This series of jaw crusher is curved pressing type. The motor drives the belts and the belt pulley, and makes the moving jaw up and down by the eccentric shaft. When the moving jaw rises, the angle between the toggle plate and the moving jaw becomes bigger, pushing the moving jaw to be closer to the fixed jaw, and the materials are crushed or split at the same time; when the moving jaw descends, the angle between the fixed jaw and the moving jaw becomes smaller, and the moving jaw plate leaves from the fixed jaw plate under the action of the tension rod and the spring. And then the crushed materials are discharged from the lower outlet of the crushing chamber. Volume production can be achieved with periodical crushing and discharging of the motor which continuously rotates the moving jaw.
