Ball mill - Wikipedia
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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 cylindrical shell rotati
Grinding Mills: Ball Mill & Rod Mill Design & Parts
Floating the mill provides an oil film between metal parts, reduces friction before starting, and eliminates the high bearing wear incident to dry starting. A floated mill also reduces the high inrush of starting current — an important advantage often overlooked when considering the …
