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.

Mill (grinding) - Wikipedia

A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

What is difference between High energy ball milling and.

There is no fundamental difference, only the attritor with the same mass of equal balls grinds 5-10 times faster. Seen from the other side, only small attritors exist, and the large ball mills are anyway more efficient than small attritors. From a purely economic point of view, the attritors have little meaning, ball mills are cheaper,.
