Mill (grinding)Wikipedia
A VSI mill throws rock or ore particles against a wear plate by slinging them from a spinning center that rotates on a vertical shaft. This type of mill uses the same principle as a VSI crusher.. Tower mill. Tower mills often called vertical mills stirred mills or regrind mills are a more efficient means of grinding material at smaller particle sizes and can be used after ball mills in a

al. 2005). In stirred mills there are no free-falling possibilities for grinding media meaning that impact action does not occur. The bead size is small typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range where ball mills are not effective or cannot reach P80 10 to 40 µm.

The IsaMill is a stirred-medium grinding mill in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
