Jaw crusher, Number Of Flower : Jaw Crusher

Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do.

A jaw crusher is generally used as a primary crusher in a crushing circuit. Product is fed into the top of the jaw crusher by an vibrating grizzly feeder. The eccentric rotating drive shaft causes the movable jaw to oscillate crushing the aggregate against a fixed jaw. Jaw crushers are run on belt drives driven by an electric motor or diesel engine. Jaw crushers are used extensively throughout the aggregate and mineral processing industry.

Jaw crushers are often used as primary crushers and are perhaps the most popular crusher worldwide. These compressive crushers are suitable for most any type of material.

In this type of crusher, reduction takes place between a stationary jaw plate and a moving jaw plate. The moving jaw plate is mounted on the pitman, which is given a reciprocating motion. Crushing takes place when the pitman moves toward the stationary jaw, compressing the material.

The Perfromance Characteristics of Jaw Crusher:

1. Crushing cavity is deep and there is no dead area, which improves feeding capacity and output;

2. High reduction ratio and uniform final product size;

3. Spacing piece type discharge-hole adjustment device is reliable and convenient;

4. Reliable and safe lubrication system, convenient replacement of parts and small work load of maintenance;

5. Simple structure, operational reliability and low operation cost.
