Jaw Crusher Description

The jaw crusher we offers are ideal for primary and secondary crushing. Jaw Crusher is one of the main types of primary crushers in a mine or ore crushing process plant and also is one of the most widely used crushing equipments in mining industry.We are famous jaw crusher manufacturers in China, and sold crusher machines to all over the world. 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


Jaw Crusher Working 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.


Brief introduction to stone crushing & screening plant

we manufactures various equipments for whole set of stone production line, and provide complete technical support for customers. The whole production line consists of Vibrating Feeder, Jaw Crusher, Impact Crusher, vibrating screen, Belt Conveyor, electric control cabinet and etc.

 

We design different production lines ranging 50 t/h to 500 t/h by combining different models of equipments.It is widely used for crushing hard limestone, granite, basalt, gravel, metallurgic slag, etc or artificial sand making for hydroelectric power, building material, high way, city construction, etc. Different models of equipments are combined to meet different customers' demands according to different craft requirements.

Process of stone crushing & screening plant

1. Big rocks are transported to the working site of stone production plant from quarry.

2. The rocks are transferred to primary crusher by vibrating feeder. Once there is a hopper prior to the vibrating feeder, the rocks are stored in the hopper firstly.  

3. The crushed materials are transferred to Impact Crusher by Belt Conveyor for secondary crushing.

4. The materials are transferred to the vibrating screen, and screened into different sizes.

5. Those aggregate with suitable size will be transferred to the final product pile; while those with unsuitable size will be transferred to the Impact Crusher for re-crushing.

 Vipeak stone crushing & screening plant

This forms a closed circuit manifold cycles. The sizes of final products will be graded and separated according to customers' requirements and application, and the deduster will be attached for the sake of environment protection.

 

Main advantages of stone crushing & screening plant

1. Customerized design

The production line is designed according to customer's requirement on the output size, types of output and capacity, as well as other factors such as material property, site conditions and purpose.
