River stone crusher, river stone jaw crusher 

I. River stone crusher, river stone jaw crusher Usage and Application

River stone crusher ( river stone jaw crusher ) in crusher is very common in the field of Mining and quarry. This kind of River stone crusher ( river stone jaw crusher ) is widely used in mining, building materials, chemical industry, metallurgy and so on. River stone crusher ( river stone jaw crusher ) is suitable for primary and secondary crushing all kinds of minerals and rocks with compressive strength less than 320 MPa.

II. River stone crusher, river stone jaw crusher Structure and Working Principle 

Structure

The River stone crusher ( river stone jaw crusher )  is mainly composed of frame,  fixed jaw plate, movable jaw plate,  left and right guard plates,  movable jaw, eccentric shaft, toggle plate,  adjustable base,  adjustable screw stem,  adjustable wedge block,  fitting of tension spring and so on.

Working Principle 

When the River stone crusher ( river stone jaw crusher )  is working, the belt and belt pulley are 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.

III. River stone crusher, river stone jaw crusher Advantage and  Main Specification

 Advantage
1. High degree of automatic operation; the entire production line requires almost no manual operation except for machine starting and stopping, routine maintenance.
2. High productivity, low investment, and good appreciation.
3. Regular end product granularity, good grain shape, and low powder.
4. Adopting high advanced central control system to ensure security and reliable operation of the entire production line.

Main specification

The machine is fixed tightly when it is sent to the port by professionale truck. Before shipped, it is covered by waterproof material to avoid moisture and rough handling.
