Ways to extended the impact crusher’s hammer life

RELEASE TIME:2017-07-14 14:05:01

impact crusher is widely used in mining, chemical, metallurgy, building materials, power and other industries commonly used crushing equipment. Among them, the hammer is the main impact crusher hammer

The impact crusher is mostly made of high manganese steel. As the high manganese steel wear resistance is not enough, poor wear resistance, short life, therefore it need to replace frequently

Factors that affect hammer life:

1. Hammer structure design and product quality

The structural design and geometry of the hammer have a great influence on the mechanical properties and the internal microstructure after heat treatment. Especially the thickness of the large hammer, the impact is more prominent. Through the analysis of the failure form of the hammerhead of different materials, it is found that the main reason for the hammer fracture is the existence of different defects in the internal or the surface. Due to the existence of defects, so that most of the hammer in the early use of the phenomenon of fracture. Therefore, in the hammer development, we must develop a reasonable casting and heat treatment process.

2. impact crusher technical parameters

impact 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's research and development capabilities, but also related to the degree of hammer impact hardening. Hammer impact hardening degree is good, its life will be extended.

3. The mass and hardness of the broken material

The greater the material block, the higher the toughness requirements, and the higher the hardness of the material, the higher the hardness requirements of the hammer material. The specific type of crusher should use the appropriate feeding particle size, which can to some extent extend the life of the hammer.

4. impact crusher internal gap adjustment

impact crusher internal clearance mainly refers to the rotor body and counterattack plate, the bar and the gap between the hammer. The size of these gaps will be related to whether there is accumulation near the poles and safety doors. If the accumulation of material, and the hammer can not be accumulated from the castle, the hammer will be subject to severe friction and wear. Therefore, in the use of the process, you must always adjust the parts of the gap, so that it is within the appropriate range.

Fine care of your crusher hammer, compared to the previous did not deliberately hammer hammer when you will find that save a lot of expenses.
