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...

Binary modelling the milling of UG2 ore using a matrix approach ...

A similar approach was used by Herbst et al. [11] to develop a multi-component-multi-size liberation model of a copper ore. The aim of the study was to develop a binary matrix model that adequately describes the grinding kinetics behaviour of chromite and non-chromite components during ball milling in a closed circuit with...
