1. Mutual wear of rubber lining plate and steel ball of ball mill: both the rubber lining plate and steel ball of ball mill are vulnerable parts. During grinding, the steel ball and material of ball mill do throw line falling movement in the barrel Xiamen Corbel tube It will collide with steel balls and materials and cause friction. In continuous operation, the rubber lining plate and steel ball of ball mill will be severely worn, which is directly related to the hardness of materials. The greater the hardness of the material, the faster the abrasion speed of the rubber lining plate and steel ball of the ball mill, which may cause equipment damage or even safety accidents in serious cases. In addition, it is also related to the ball of the ball mill. The size and quantity of the ball will affect the service life of the rubber lining plate of the ball mill. If the ball mill is in operation, increasing the amount of steel balls or filling steel balls with larger diameters will increase the wear of the rubber lining plate of the ball mill. 2. The heat treatment process of the rubber lining plate of the ball mill is unreasonable: the unreasonable heat treatment of the rubber lining plate of the ball mill will not only increase the wear of the lining plate, but also affect the yield strength of the lining plate, resulting in the fracture of the bolt of the ball mill under the large shear force. In the actual operation, the staff lacked the understanding of the lining plate material and the heat treatment processing of the ball mill rubber lining plate was insufficient, so the strengthening effect of the ball mill rubber lining plate was not in place and the strength was low. When impacted by steel balls and materials, Corbel tube Where can I find it? Plastic deformation often occurs. 3. The material of the rubber lining plate of the ball mill is unreasonable: the material of the rubber lining plate of the ball mill and its heat treatment process are the key to determine the mechanical performance of the lining plate. If the material of the lining plate is not properly selected, its fatigue strength and life will be greatly reduced, which will not meet the requirements of the ball mill, or even plastic deformation or bulge will occur.
