Size reduction and homogenization with ball mills

2014-4-23  RETSCH ball mills are used for the pulverization of soft, fibrous, hard and brittle materials. They achieve a very high final fineness down to the submicron range. The feed size depends on the mill and can have a maximum size of 10 mm. If the sample feed size is larger than this then the sample must first undergo preliminary size reduction.

Ball Mills an overview ScienceDirect Topics

In a ball mill, size reduction takes place by impact and attrition. In a vertical mill the bed of material is subject to such a high pressure that individual particles within the bed are fractured, even though the particles are very much smaller than the bed thickness.

Effect of ball and feed particle size distribution on the

2018-6-1  This approach has the added advantage in that different particle sizes can be effectively milled in a ball mill because each media size can effectively break a particular particle size during the size reduction process ensuring that the product fineness is optimized.

SIZE REDUCTION AND SIZE SEPARATION

2020-2-28  At this speed the balls are carried almost to the top of the mill and then fall in a cascade across the diameter of the mill. By this means the maximum size reduction is obtained by impact of the particles between the balls and by attrition between the balls. Generally it is 0.5 cycles per seconds (cps).
