The hammer is the most vulnerable part of hammer crusher, which directly affects the working efficiency of hammer crusher. Therefore, it is very important to protect and maintain the hammer during the working process of the hammer crusher equipment. One of the problems we will encounter is the overheating of the hammer. There are many reasons for the overheating of the hammer. It will be more troublesome to solve. Different solutions should be used for the overheating of the hammer caused by different reasons. The following is a brief analysis of the common causes of hammer overheating.
1. If the knocking sound appears in the elastic coupling, then the reason can be determined that the pin is loose and the elastic ring is worn. The corresponding solution is to stop and tighten the pin nut and replace the elastic ring.
2. If the bearing is overheated, the cause can be determined to be insufficient or excessive grease, or the grease is dirty and deteriorated, and the bearing is damaged. The corresponding solution is to add an appropriate amount of grease, the grease in the bearing should be 50% of its space volume, clean the bearing, replace the grease, and replace the bearing.
3. If the output is reduced, the reason is that the screen gap is blocked or the feeding is uneven. The solution is to stop, clear the blockage in the screen gap or adjust the feeding structure.
4. If there is a knocking sound inside the machine, then the reason must be that non-broken objects enter the inside of the machine; the fasteners of the lining plate are loosened, and the hammer hits the lining plate; the hammer or other parts are broken. The corresponding solution is to stop and clean the crushing chamber; check the fastening of the lining plate and the gap between the hammer and the screen; replace the broken parts.
5. If the particle size is found to be too large when the material is discharged, the reason is that the hammer head is too worn or the screen bar is broken. The solution is to replace the hammer or replace the screen.
6. If there is a sudden decrease in the amount of vibration, the reason is that the static balance of the rotor is unsatisfactory when the hammer is replaced or due to the wear of the cone head; the hammer is broken, the rotor is out of balance; the pin shaft is bent and broken; the triangular disc or disc is cracked ; Anchor bolt umbrella. The corresponding solution is to remove the hammer and select the hammer 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 opposite hammer shaft, that is, the static balance meets the requirements; replace the hammer ; replace the pin shaft ; Welding repair or replacement; Tighten the anchor bolts.
Small details cannot be ignored. As an important part of the hammer crusher, the hammer should pay more attention to its working conditions. Regular inspection and maintenance are required so as not to delay the normal work of the equipment, so as not to affect the work progress and efficiency, and to save wear and tear. Investment costs, improve production profits. At the same time, it is also necessary to choose a high-quality and suitable hammer.
