What is CJ Series Jaw Crusher?

CJ Series Jaw Crusher is a new generation of upgraded European-type jaw crusher, optimized and upgraded on the basis of traditional jaw crushing technology. Compared with ordinary PE series jaw crushers, the CJ model adopts deep V-shaped crushing cavity, no dead zone design and reinforced integral frame, which greatly improves feeding capacity and crushing efficiency.
This machine is specially used for primary coarse crushing in mining, quarry, aggregate processing and construction waste recycling. It can handle high-hardness materials such as granite, basalt, iron ore, copper ore and river stone stably. It is the preferred core equipment for large and medium-sized fixed crushing lines and mobile crushing stations.

Application of CJ Series Jaw Crusher

Working Principle of CJ Series Jaw Crusher

The CJ series jaw crusher adopts motor-driven eccentric shaft transmission. When the equipment is running, the movable jaw plate makes periodic reciprocating motion toward the fixed jaw plate.
Bulk materials enter the deep V crushing cavity and are squeezed, crushed and bent by high-strength jaw plates. Small qualified particles are discharged from the bottom gap, while large materials stay in the upper cavity for continuous crushing. Finally, standardized coarse aggregate is formed to complete efficient primary crushing.

When you want to build a stone crusher plant, there are several important factors to be considered:

1. The maximum stone size before crushing. From this data, the feed opening of jaw crusher can be confirmed;

2. How many tons or cubic meters per hour you want to process?

3. The feeding size of the next crushing stage.

The above three factors need to be considered together. The most important factor is the capacity of jaw crusher, even the stone size is smaller, but in order to reach the capacity, you have to choose a bigger jaw crusher. Meanwhile, you also have to consider the output size of jaw crusher, if it is suitable for the secondary crusher or not. It is a complicated stone crusher plant design, please contact our experienced expert to get more support.

Why Choose CJ Series Jaw Crusher Over Traditional Jaw Crusher
  • Optimized Deep V Crushing Cavity: Adopts deep V cavity structure without crushing dead zone, larger feeding capacity, higher filling rate and better granularity uniformity, effectively improving hourly output.
  • Reinforced Modular Welded Frame: Integral thickened steel plate welding and modular assembly structure enhance overall rigidity, avoid structural deformation during heavy-load operation, and extend service life.
  • Hydraulic Discharge Size Adjustment: Equipped with automatic hydraulic adjustment system, the discharge gap can be adjusted quickly and accurately, reducing manual operation time and downtime.
  • Large Crushing Ratio & Uniform Output: Optimized jaw plate tooth shape and stroke design realize larger crushing ratio, uniform finished particles and less powder, improving aggregate quality.
  • Strong Adaptability for Hard Materials: Suitable for high-hardness and super-hard stone and ore, stable operation, low failure rate under long-term heavy load.
  • Easy Maintenance & Low Operating Cost: Reasonable structural layout makes wear parts replacement faster. The vulnerable parts have longer service life, reducing daily operation and maintenance costs.
  • Flexible Installation Adaptation: Compact body and low height design are suitable for both fixed crushing plant and mobile crushing trailer layout.
