Hammer Crusher

Hammer’s Life

Hammer crusher is widely used in mining, chemical, metallurgy, building materials, electricity and other industries used crushing equipment. Hammer is the main wear parts  which has direct impact of the hammer crusher crushing efficiency.Currently for the majority of hammer crusher, hammer is made of high manganese steel. Not enough due to the high manganese steel wear resistance, abrasion resistance is poor, life is short, requiring frequent replacement. Hammer at work, in addition to being hit, but also by the impact of the material, so that long-term repeated use, the hammer’s face would be destroyed, so that the surface shape changes. Factors affecting the life of the hammer:

1. Hammer’s structure design and product quality
Hammerhead structure design and geometry of their mechanical properties after heat treatment and the internal microstructure have a great impact. Especially the thickness of the large size of the hammer, the impact is more prominent. By the hammer of Fracture in the form of different materials analysis, the main fracture is caused by the hammer or the internal surface of varying degrees of impairment. Because the defect, so that most of the hammer in the initial period of fracture phenomena. Thus, in the hammer production, must develop a reasonable casting and heat treatment process.

2. Hammer crusher’s technical parameters
Hammer crusher technical parameters will also affect the life of the hammer, which is the main rotor power and speed. They are not only related to the crusher capacity is also related to the degree of hardening of the hammer impact. Good degree of hardening of the hammer impact, its life will be extended.

3 .The degree of crushing blocks and hardness of the material
The greater the degree of the material block, the higher its toughness, and higher material hardness, material hardness of the hammer higher. Specific type of crusher should be appropriate to the particle size, which will extend to some extent, the life of the hammer.

4 .Crusher internal clearance adjustment
Hammer crusher is a major gap within the rotor body and back plate, grate, and the gap between the hammer. The size of these gaps will be related to the grate, and whether the plot near the security gate material. If the plot material exists, but the hammer can not be expected from the grate of the plot on the depressed, the hammer would be a serious friction and wear. Therefore, the use of the process, must often adjust the part of the gap, it is in the proper range.
Hammer crusher hammer on the life of many factors, the above four points are Xinhai mechanical hammer crusher based on years of production experience and customer feedback summary information derived for the hammer crusher for reference, For more information, you can consult an expert
