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.

Size Reduction an overview ScienceDirect Topics

The size of the milling media (typically 20:1 for ball:powder diameter) also influences size, morphology and microstructure of the powder. To produce fine powders, it is recommended to mill in several steps while reducing successively the milling media size, as one milling step usually induces a particle size reduction of about factor 10.
