Ball mill - Wikipedia

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow.

Vibration ball mills: Have they a place in pigment and resin .

Abstract: The vibrational ball mill has been around for close on fifty years and yet, it seems to have made only minor impacts in the pigments and resin industries. Looking at the techniques of vibrational milling one notes that such a method of comminution, or grinding, is very much faster than, say, a conventional ball mill.
