Application fields and troubleshooting methods of impact crusher

1. Application of impact crusher

Impact crusher is widely used in industrial sectors such as building materials, chemical industry, coal, etc. Fine crushing, sandstone, coal, asbestos, graphite and rock salt, etc.

2. Performance characteristics of impact crusher

The crushing ratio of the impact crusher is large, generally 10-20, up to 50-60; the crushing process is simplified, the structure is simple, and the manufacture is easy; easy to use and maintain , can be used for selective crushing and so on. However, due to the concentrated wear of the plate hammer, its application in crushing hard materials is limited.

3. The working principle of the impact crusher

The impact crusher is a crushing machine that uses impact energy to crush materials. When the material enters the action area of ​​the wind hammer, the high-speed impact of the wind hammer causes the crushed material to be continuously thrown to the counterattack device installed above the rotor for crushing, and then bounces from the counterattack liner back to the action area of ​​the hammer to counterattack again. , the materials enter the first, second, third, and counterattack chambers in order from large to small for repeated crushing. After the material is crushed to the required particle size, it is discharged from the lower part of the machine. Adjusting the gap between the impact frame and the rotor frame can achieve the purpose of changing the discharge particle size and material shape.

4. How to solve the problems in the operation of the impact crusher?

A. The bearing temperature is too high. Remedy: 1) Check whether the grease is suitable, the grease should fill 50% of the bearing seat volume; 2) Clean the bearing and replace the grease; 3) Replace the bearing.

B. There is a knocking sound inside the counterattack circuit breaker. Remedy: 1) Stop the machine to clean the crushing cavity. 2) Check the tightness of the lining plate and the clearance between the hammer and the lining plate; 3) Replace the damaged parts.

C. The counterattack is broken and the discharge is too large. Remedy: 1) Adjust the gap between the front and rear counterattack racks or replace the liner and plate hammer; 2) Adjust the position of the counterattack rack to make the gap between the two sides and the rack liner even, and the liner on the rack is worn, that is, replace it.
