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.

Frequently Asked Questions | The Jet Pulverizer Company

A ball mill with a classifier will produce a fine product but the particle size distribution curve is very wide and when the correct average size is reached the number of fines is usually too high. Ball mills can be lined with ceramics to reduce contamination from abrasive products but there is constant wear of the media, which.

A COMPARISON OF WEAR RATES OF BALL MILL GRINDING .

SAG mill balls experience both significant abrasive and impact wear due to their large. (75 – 100 mm) diameters. Ball mill balls experience a greater number of impacts, but at lower magnitude than SAG mill balls, due to the smaller ball size, and smaller mill diameter. Feeds are typically highly abrasive, contributing 10 – 15.
