Small jaw crusher is a kind of coarse and medium crushing equipment which can deal with high hardness stone, rock and construction waste. It is still widely used in metallurgy, chemical industry, building materials, electric power, transportation and other industrial departments because of its simple and firm structure, reliable operation, easy maintenance and repair, and low production and construction costs.

Application of Small Jaw Crusher
Small jaw crusher is mainly used to crush various materials with compressive strength not exceeding 320 MPa, such as granite, limestone, olivine and quartz. In addition, it can also process other non stone minerals or be used in other industries, such as chemical crushing, industrial crushing, building materials processing and so on.



Advantages
1. The configuration is simple and reliable, without redundant parts, and the later maintenance cost is low.
2. The working mode is simple, and local conversion is realized without installation.
3. The cooperation between equipment is smooth and saves floor space.
 

The working part of the small jaw crusher is two jaw plates, one is fixed jaw plate (fixed jaw), which is vertically (or slightly inclined at the upper end) fixed on the front wall of the machine body, and the other is movable jaw plate (movable jaw), which is inclined and forms a crushing cavity (working cavity) with the fixed jaw plate.
The movable jaw plate makes periodic reciprocating motion against the fixed jaw plate, sometimes separate and sometimes close. During separation, the material enters the crushing chamber and the finished product is discharged from the lower part. When approaching, the material installed between the two jaw plates is crushed by extruding, bending and splitting.
