PCW Hammer Crusher is a new type of product developed and produced with the advantages of a new type of high efficiency and energy saving and a variety of crushers. It is suitable for crushing various medium hardness (≤2000kg/cm2) limestone, phosphate rock, asbestos ore, coal block, gypsum, ore and other materials. It is especially suitable for large, medium and small quarries. 
This machine has six major features:
1. Large crushing ratio: The particle size of the feed 450-550mm is 0-55mm, of which 20-40mm is more than 60%.
2. Simplify the process: The original primary and secondary crushers are combined to save equipment investment and reduce maintenance costs.
3, saving electricity, save 30-50% compared to similar equipment
4, long life: the use of high wear-resistant alloy materials, carefully manufactured, wearing parts increased 2-3 times the service life.
5. High efficiency: The machine has a large-capacity crushing bin and a wraparound sieve plate, so the output material is large and the wear is small. The discharge particle size can be achieved by adding or subtracting hammers or replacing the sieve plate.
6, equipment investment is small, the cost of recovery is fast.
Working principle and structure characteristics: After the bulk material enters the machine, it is blocked by the material screening bracket while being impacted by the hammerhead, which not only reduces the contact area between the material and the hammerhead, but also avoids the sudden infarct of the rotor. After the impact, large pieces of material are shot in the crushing cavity to form a self-propelled. The stone overflows or falls into the cell from the straight screen and is struck by the hammer to form a stone. Finally, it is discharged from the arc plate. The machine makes full use of the rough broken, fine breaks the "breaking into two" principle of crushing, and the material and material are self-propelled. The mechanism of impact is to make full use of the impact-type crushing principle in the coarse material crushing process, and to increase the material running speed, so that the material will have self-collisions and improve the crushing effect. The crushing finished product grain shape is good, and is mostly cubic. Due to the small amount of needle flakes, the pellets have high mechanical strength and are suitable for breaking stones in all industries such as high-grade highways and high-rise buildings.
The feed material is 400-600mm, and the discharge material is less than or equal to 10mm, and the powder is more than 65%. It is the ideal replacement product in the current "more broken and less grinding" process. The product is small in size, high in output, stable in performance, simple in operation and low in maintenance cost. Suitable for the crushing of hard materials such as limestone, gangue, gypsum, dolomite, and shale.
Mining machines such as hammer crushers and jaw crushers have played an important role in the industrial construction of the country, and have extended to such important national fields as agriculture and forestry, affecting the country's comprehensive development. It not only reduced production costs and increased efficiency for limestone crushing, but also strengthened the belief in the determination of the domestic production of 10,000 tons of clinker. Therefore, in the design, China's crusher industry should break through the conventions, gain a technical start, and continuously improve Structure and perfect its performance.
