stirred-ball attrition mill . Abstract −To develop a high-performance structured catalyst, the fine grinding characteristics of alumina was inves-tigated by a stirred-ball attrition mill. The grinding kinetics approach was successfully applied to the analysis of particle size distributions …

calculation of product top size of ball mill

Ball mills may be able to efficiently reduce coarse aggregate to particles as small as 30 to 40 microns. Below 30 microns, the advantages of a horizontal stirred mill become dramatic and below a certain point, the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption.

Predicting the product particle size distribution from a ...

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 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 ...

Choosing the Best Media Mill For Your Wet Grinding Application

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.
