2. Production procedure
Fabricated from steel plate, the shell and heads are typically an integrated welded unit designed for high impact, with machined trunnion flanges for precise alignment.
Ball mill heads and trunnion checking before assembly



Ball mill shell welding, after welding flaw detection or crack detection should be done, to guarantee the perfect welding joint



Ball mill processing on the horizontal lathe, it is a key heavy-duty machining process, mainly involving the precision machining of the mill heads trunnion and outer diameter of the shaft shell. High-precision rotational accuracy is achieved through this horizontal lathe.

Ball flange and heads are assembled, then drilling holes to ensure connection accuracy





Installation of ball mill head liners








Installation of the shell liners




Manhole is important, pine wood plate for backup to make sure all the liners are in the same level


Thickness of the ball mill heads liners, shell liners, material: ZGMn13Cr2
