Ball Mill End Cover for Sale

The ball mill end cover, sometimes referred to as the ball mill head, is a crucial component of the ball mill, located at both ends of the mill, covering the end of the ball mill shell. The ball mill end cover is typically a circular metal component whose function is to seal the two ends of the ball mill, preventing material and grinding balls from overflowing from the ends of the mill, while also providing support and stability to the cylinder. It is usually connected to the ball mill shell by bolts to ensure sealing and stability. Positioned at both ends of the ball mill, the end cover is supported by the ball mill bearings and primarily serves to support the material, ball mill shell, and grinding media. The root fillet of the ball mill end cover in the circumferential control zone of the ball mill is a stress concentration area, thus requiring extremely high casting quality for the ball mill end cover.

Classification of Ball Mill End Covers

Separate ball mill end cover, not cast together with the trunnion

This structural form involves separately casting the ball mill end cover and the ball mill trunnion, and then assembling them during the ball mill assembly process. This approach ensures the casting quality of both the end cover and the trunnion, guaranteeing the quality of both components. It effectively avoids various defects that may occur when the trunnion and end cover are cast together, such as preventing larger stresses and looseness due to uneven thermal contraction and avoiding casting defects caused by an oversized ball mill end cover diameter at the casting interface. Therefore, a separate ball mill end cover structure is more suitable for use in large-diameter ball mills.

The ball mill end cover and the ball mill trunnion are cast as one piece

The ball mill head is the general name for the ball mill end cover and the ball mill trunnion. It refers to the structure in which the ball mill end cover and the ball mill trunnion are cast as one body. This structure no longer has the problem of connecting the end cover and the trunnion installed later, making the structure simple, easy to install, and more suitable for small ball mills. This structure can reduce the manufacturing process, reduce the cutting process and cutting surface, and consume less raw materials. During installation, the ball mill head, which is composed of the end cover and the trunnion cast together, is directly welded to the ball mill shell. The connection is reliable, time-saving and labor-saving. There is no need to reconnect the end cover and the trunnion, and the connection of bolts and rivets is no longer required.

Rich processing experience, reliable quality

AGICO boasts extensive experience in ball mill end cover processing. We continuously introduce new technologies and techniques to enhance the wear resistance and compressive performance of the ball mill end covers. Additionally, we employ secondary flaw detection instruments to inspect the internal structure of the end covers, ensuring that our products meet the highest quality standards.

Close fit with components, no leakage issues

The feed ball mill end covers produced by AGICO CEMENT can be adjusted according to specific equipment requirements, ensuring a tight fit between the end covers and the feeding components. This eliminates gaps and effectively prevents leakage issues caused by poor alignment between the ball mill end covers and the components.

Stable operation, long service life

The hollow shafts used in the ball mill accessories we process are cast from high-strength steel. Before casting, our professional engineers optimize the process structure of the ball mill end covers and hollow shafts based on the operational characteristics of the ball mills. These measures significantly enhance the stability of the components during prolonged operation, extending their service life.
