Why the blades of metal shredders are easy to wear out

2021-05-25 10:30:21 By Henan Honest

The blade of the metal shredder is the core component of the entire equipment. If the operation is not correct, it may cause the wear of the blade, shorten the service life of the blade and greatly reduce the production efficiency. So what incorrect operations will cause the blades of the metal shredder to wear out?

1. The surface heat treatment of the equipment is improper. Because the hammer head is made of alloy steel, the head is carburized and quenched, and the quenching hardness is HRC60~65. If the heat treatment is improper, it will wear out quickly during use. Grasp the strength of the treatment and minimize the occurrence of heat treatment errors.

2. The thickness of the blade of the equipment is small. The rectangular double-pin hole hammer is commonly used. Its service life is 200~500 hours. Although the thickness is small, it can reduce the weight and increase the shredding productivity, but the life is short, and it is generally multi-functional The hammer of the shredder is 2~3mm, and other hard materials are 6~8mm. It can be seen that the hammer with a smaller thickness is more suitable for the production of double-shaft shredders.

3. The air suction volume is too large. The equipment generally adopts air suction methods to reduce the temperature and humidity inside the machine and avoid dust leakage. However, if the air suction volume is too large, it will cause uneven wear of the hammer head. The air volume should be properly controlled.

4. The gap between the hammer head and the screen should not be too small, generally 4~12mm, and the hard material 10~14mm.

The wear of most metal shredder blades is that the hammer head and the material of the shredder do not match. Therefore, if the blade wear occurs, we should first check whether it is caused by the material. If the hammer head does not match the material , You need to make changes in advance, which can greatly increase the service life of the metal shredder.
