Attritor Mills & Media for Chocolate Processing Update
A useful and simple equation which allows us to see how the attritor fits into the family of mills is M × V, mass times velocity. For example, ball mills use large media, normally ½" or larger, and run at a low 10-50 rpm. Other mills, such as sand, bead, and horizontal, use smaller media from 1/64" to 1/8", but run at a very high 800-1200 rpm.
