There are two types of ball grinding mill in the AAC production line: dry ball mill and wet ball mill. A ball mill is widely used for material preparation section in AAC production lines.

The materials are conveyed evenly into the first chamber which is equipped with stepped liner plate or corrugated liner plate and each size of grinding media (steel ball or cylpebs). As the shell rotates, the balls are lifted up on the rising side of the shell and then they cascade down (or drop down on to the feed), from near the top of the shell. In doing so, the solid particles in between the grinding media and ground are reduced in size by impact.
After finishing coarse grinding in first chamber, the materials would be conveyed to the second chamber which is equipped with flat liner plate and steel balls for further grinding to obtain the powder materials meeting the requirement about fineness.
