cheap price mining equipment mobile rock stone crusher machine jaw crusher for sale
Usage and Application:
The jaw crusher is widely used in mining, building materials, chemical industry, metallurgy and so on. It is suitable for primary and secondary crushing all kinds of minerals and rocks with compressive strength less than 320 MPa
The belt and belt pulley is driven by a motor, and the movable jaw moves up and down via eccentric shaft. The angle between fixed jaw and movable jaw becomes smaller when the moving jaw runs down, then the materials are crushed into pieces. It becomes bigger when the movable jaw runs up. The movable jaw plate leaves the fixed jaw plate under the action of tension rod and spring, then the end products come out from the crushing cavity.
1. Simple structure, convenient maintenance; 2. High crushing ratio, even output granularity; 3. High reliability, low investment; 4. Low noise, less dust
