How to strengthen the protection of the end cover of the end of the ball mill liner

The ball mill is the main equipment for the grinding operation of the factory. Although the end mill cover of the ball mill has a certain protective effect on the end cover during use, the slurry will flow into the gap between the liners, and the partial bolts will be loosened and the end of the liner. The gap formed between the covers causes wear on the end caps. Generally, there are two types of wear of the end cap, one is the wear and crack formation of the inner cone surface of the end cap, and the other is the wear of the inner wall of the hollow journal of the end cap during the grinding process. Since the various parts of the end cap are inevitably worn by the intrusion of the slurry, here is a brief introduction on how to strengthen the protection of the end cover of the ball mill end cap.

First, local welding, this method is mainly the repair of the end cap after wear, clean the end cap wear surface before welding, the welding rod is heated to 300 ° C for welding work, after the completion of the welding should be more in need of insulation treatment. However, this protection method is easy to form welding stress, and it is also difficult to ensure the smoothness of the welding surface. Second, the end face lining rubber, the rubber lining is designed to be in the shape of two lining plates, and a lining plate is staggered during installation. The end cap liner overlap can be protected to the utmost extent. This method also has a certain effect on reducing noise, but the rubber pad is not easy to locate and difficult to install; Third, the repair agent coating, this method mainly uses metal repair agent to repair the end cap wear parts, and the end cover is repaired before repair. The worn parts are cleaned and repaired according to the requirements of the repair agent. This method can generally restore the original thickness and smoothness of the end cap. If it can be repaired with special metal particle repair agent, the operation is simpler and faster, but the general cost is higher; Fourth, the magnetic block is filled, after the ball mill end cap liner is installed, the gap between the two liners is filled differently. The thickness of the magnetic block, this method can fully block the gap between the lining plates, to avoid the inflow of the slurry along the lining gap during the grinding process, causing wear on the end cover.

The above is the measure recommended by Yogie to strengthen the protection of the end cover of the end cap liner of the ball mill. In actual production, it should be selected according to its own situation. Yogie also provides services such as mine design, research, equipment manufacturing, installation, commissioning, and worker training.
