Jaw Crusher is widely used in stone mining, metallurgy industry, building material, highway, railway, water conservancy and chemical industries. Various material with compression resistance less than 320MPa can be crushed. This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. Because it is primary crusher, Jaw crusher is designed for long life service with minimum maintenance for hard, tough, abrasive material and overload high capacity.

                            
Features: 
1)big crushing ratio 
2)uniform products size 
3)easy maintenance 
4)long useful lifetime                                 

Operating Principle: 
Primary jaw crusher is typically of the square opening design, and secondary jaw crusher is of the rectangular opening design. Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw board, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates decide the crusher product size gap, or the size of the crushed product from the jaw crusher. The rock remains in the jaw until it is small enough to pass through the gap at the bottom of the jaws.
