The ball mill head, also known as the ball mill end cap and trunnion, is a structure in which the cap and trunnion are cast as a single piece and located at each end of the ball mill, covering the ends of the mill housing. This structure reduces manufacturing steps, cutting processes, and cutting surfaces, as well as reducing raw material consumption. During installation, the ball mill head, with the cap and trunnion cast as a single piece, is welded directly to the mill housing, providing a reliable connection and saving time and effort.

Integrated ball mill end cap

The split end cap of the ball mill is made by casting the end cap and the trunnion separately, followed by assembling the two components during the ball mill assembly process. This effectively avoids several defects that can occur when the trunnion and end cap are cast together. The structure of the split end cap of the ball mill is more suitable for large diameter ball mills.
