Solutions to the 4 major failures of hammer crusher

The hammer crusher is suitable for finely crushing medium hardness and brittle materials in mining, cement, coal, metallurgy, building materials, highway, combustion and other industries.Hammer crushers (hammer crushers) generally have fans and grading machines, through which the products are blown into the hammer crusher. The hammer in the hammer crusher hammers and crushes the products and then blows into the grading with the wind. The machine, the classifier classifies the product, and the qualified product is the product;the unqualified ones enter the unqualified bin and then into the crusher for crushing. The movable jaw is hung on the mandrel, which can swing left and right. When the eccentric shaft rotates, the connecting rod reciprocates up and down. The two thrust plates are driven to reciprocate, thereby pushing the movable jaw to reciprocate left and right to realize crushing and unloading. There will be some problems when the hammer crusher is used for a long time. How to solve these problems.

1. There is percussive sound inside the hammer crusher. We can adopt the following solutions: stop in time to clean the crushing cavity; check the fastening of the liner and the gap between the hammer and the screen; replace the broken parts.

2. The bearing of the hammer crusher is overheated. We can use the following solution: add a proper amount of grease; grease in the bearing should be 50% of its space volume; clean the bearing; replace the grease; replace the bearing.

3. The output granularity of the hammer crusher is too large. We can adopt the following solution: replace the hammer head; replace the sieve bar. The output is reduced, we can adopt such a solution: stop the machine, clean up the blockage in the gap of the screen; adjust the feeding mechanism.

4. The hammer crusher machine vibrates. We can adopt this solution: remove the hammer head and select the hammer head according to the weight, so that the total weight of the hammer on each hammer shaft is equal to the total weight of the hammer on the hammer shaft. The static balance meets the requirements; replace the hammer head; replace the pin shaft; repair or replace by electric welding; tighten the anchor bolts. The elastic coupling produces a knocking sound. We can use this solution: stop and tighten the pin nut; replace the elastic ring.
