Jaw crusher introduction

Jaw crusher is a crushing machine and developed very early. With simple and solid structure, reliable work, easy maintenance and repair and low production and construction fees, it has long been widely used for the coarse, medium and fine crushing of various kinds of ores and rocks whose compression strength is 147-245MPa in many industrial departments such as metallurgy, chemistry, building material, power plant and transportation.

Jaw crusher basic structure

The equipment consists of bracket, movable jaw, eccentric shaft, jaw plate and toggle plate etc. Eccentric shaft is driven to rotate by motor and jaw runs on adjusted track to crush materials in crushing chamber.
The bracket is welded by steel plate or casted. On the front wall of bracket, jaw plate is fixed by wedge-shaped bolt. Edge protection plate is equipped on inside wall of bracket to prevent abrasion. The movable jaw is a shaped casting with a movable jaw plate on the face. The upper part of jaw is hung on upper and lower parts of bracket is supported on toggle plate by eccentric shaft and roller bearing. The flywheel and grooved pulley are equipped at both ends of eccentric shaft.
The other end of toggle plate is supported on adjusting beam. Besides supporting jaw, the toggle plate plays the role of insurance during load increase caused by the uncrushed material's entry into crushing chamber. It will be broken to protect other pieces from damage.

Jaw crusher working principle
The working manner of this series crushing machine is dynamic extrusion type, and its working principle goes like this: the electro motor drives the belt and belt wheel to make the movable jaw to move up and down through the eccentric shaft, and then movable jaw goes up, the angle between the toggle pate and the movable jaw is bigger, thus pushing the movable jaw to get close to the fixed jaw, and at the same time, the materials are crushed or smashed, thus reaching the goal of crushing; when the movable jaw goes down, the angle between the toggle pate and the movable jaw is smaller, under the effect of the draw bar and the spring, the movable jaw moves always from the fixed jaw, and then the crushed materials will be discharged out from the lower mouth of the crushing chamber. With the continuous rotation of the electro motor, the movable jaw of the crusher will do periodic motion to crush and discharge the materials, thus realizing mass production.
