Attrition mill operating characteristics - ScienceDirect

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

Nov 02, 2008· Comminutor hammer mill. Comminutor hammer mills are also considered attrition-style mills and reduce the particle size with several rotating hammers or knives or a rotor bar. The blade type, speed, and screen size are the important variables that influence the milling process (1).

Corn wet milling – Starch industry equipment - ANDRITZ

Wet milling, also called wet media milling, is a process in which particles are dispersed in a liquid by shearing, by impact or crushing, or by attrition. Wet milling can be a more intensive process, but it can reduce a bulk product into more components, and into finer particles in the micron & submicron (or nanometer) particle size range.
