Hongji Product Introduce

Jaw crusher is one of the most popular stone crushing machines in the world and it is ideally suitable for primary and secondary crushing. The highest compression strength of the materials to be processed is 320 Mpa. Our design and production are of high position both at home and abroad. This series jaw crusher has the advantages of big reduction ratio, equal product granularity, simple structure, reliable working condition, convenient repair and economical operation. This series jaw breakers mainly used in the industries of metallurgy, mine, chemical industry, cement, construction, refractory material and ceramics. The jaw breaker can crush the medium and above medium ore and rocks for medium and fine crushing.

Advantages of Jaw Crusher

1. Effectively solves the problem of high operation rate and little maintenance time caused by low output of limestone crusher.

2. Can complete the crushing work of large-sized limestone.

3. The blending of the two materials is even and the mixing quantity of the desulfurized limestone is greatly increased.

4. The electricity needed is reduced.

5. The granularity of the wastes is small.

6. Effectively improves the labor strength and the working environment of the workers

Working Principle of The Jaw Crusher

The main structure of the Jaw Crusher are composed of stander, eccentric shaft, belt pulley, flywheel, movable jaw plate, wrist plate ,adjustable gap screw, offsetting spring, fixed jaw plate. The wrist plate also has the effect of guarding.

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.
