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

high-energy ball milling - an overview | ScienceDirect Topics

The range of high-energy ball milling equipment divides, approximately, into two categories: small, high-energy laboratory devices, and larger facilities capable of milling commercial quantities of powder. The former category includes SPEX shaker mills and planetary ball mills.

Ball Mill - an overview | ScienceDirect Topics

A variant of the rotating (or tumbling) ball mill is the planetary ball mill. This variant imparts a higher degree of energy in an attempt to create finer or more homogeneous powder size distributions. Instead of relying on gravity to accelerate the balls, the mill chamber is placed off-center on a rotating platform.
