The long-term use of the mill is prone to these three major failures

1. The cylinder is deformed. There are two main reasons for the deformation of the simplified body of the Raymond mill. When the mill stops working for a long time, the compact body and some materials cannot be unloaded technically.

2. Poor lubrication. Because the fitting clearance of the newly assembled parts is small,  it is difficult to ensure the uniformity of the fitting clearance, and the lubricating oil is not easy to form an even oil film on the friction surface to prevent wear. Thereby it reduces the lubrication efficiency and causes early abnormal wear of parts. In severe cases, it will cause scratches or bites on the precisely matched friction surfaces, resulting in failures.

3. Looseness occurs. Newly processed and assembled parts have deviations in geometric shape and matching dimensions. In the initial stage of use, due to the impact of alternating loads such as shock and vibration, as well as the influence of factors such as heat and deformation, and excessive wear and tear, it is easy to use originally fastened parts and become loose.
