 1. Overview of jaw crusher:

In industry, crushers are machines which use a metal surface to break or compress materials. Mining operations use crushers, commonly classified by the degree to which they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations. Each crusher is designed to work with a certain maximum size of raw material, and often delivers its output to a screening machine 

 2. Features of jaw crusher:

1. The broken cavity using "V"-shaped structure, so that the actual width of feed is same as nominal line width;
2.  The broken cavity is deep and without dead zone, increased capacity and output feed;
3.  Lubrication system is safe and reliable, convenient of replace parts, easy to maintenance;
4.  The outlet use of pad-style adjustment devices, convenient and reliable, large of adjustment range, and increase the flexibility of the equipment;
5.  Low noise, less dust

3.Working principle of jaw crusher:

 In operation, the raw material (of various sizes) is usually delivered to the primary jaw crusher's hopper by dump trucks, excavators or wheeled front-end loaders. A feeder device such as a conveyor or vibrating grid controls the rate at which this material enters the crusher, and often contains a preliminary screening device which allows smaller material to bypass the jaw crusher itself, thus improving efficiency. Primary jaw crushing reduces the large pieces to a size which can be handled by the downstream machinery.
