PE600*900 small rock jaw crusher 
 
small rock jaw crusher is ideally suitable for primary and secondary crusher for material with compression strength less than 320MPA. Jaw Crusher is of high crushing ratio, larger capacity, well-distributed final product size, simple structure, reliable performance, convenient maintenance, lower operation cost, etc. It is widely used in mining, metallurgy, construction, highway, railroad, and water conservancy, etc.
 
Working principle of small rock jaw crusher
 
small rock jaw crusher have a crushing chamber which is composed of a movable jaw, a stationary jaw and a edge plate.he motor-driven belt and pulley, the up and down movement of the movable jaw by the eccentric shaft when the movable jaw rises, the angle between toggle plate and moving jaw becomes larger, thus promoting the moving jaw plate close to the fixed jaw plate, its material is crushed or split pieces to achieve the purpose of crushing; When the movable jaw down, the toggle plate and moving jaw angle between the smaller, movable jaw plate trolley, spring next, to leave the fixed jaw plate, the crushed material is discharged from the crushing chamber mouth. With the continuous rotation of the motor broken motor jaw the periodic motion crushed and excreta material, to achieve mass production
 

Application of small rock jaw crusher:
 
1.widely applied in mining, road&railway, concrete, chemical and building material industries.
2.Ores and rocks with various hardness
3.Concrete basis and steel structure basis
4.Stationary, half-mobile and mobile applications
 

Main Advantages of small rock jaw crusher:
 
1. The machine has a deep crushing cavity and the frame employs the joggle joint welding and entirely annealing technology which make the crusher a simple, durable and robust structure and improve the capability and the crushing ratio.
2.Digital simulation of the operating trace and speed of the movable jaw ensure a high capacity and low consumption rate of the ware parts.
3.Utilization rate of the tooth plate has been increased by using segmented tooth plates which are replaceable.
4.Hydraulic adjustment of the discharge opening ensures a more convenient and safe operation.
5.The service life of the toggle plate and adjustment seat has been developed by the double-layer adjustment seat with arc-shape liner inside it which will disperse the partial pressure evenly.
6.The frame could be taken into upper part and lower part which can be fixed together again by dowel pins. This sort of structure makes users easy to assembly, disassembly, transport and install the crusher.
7.The small rock jaw crusher employ the American technology.
