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.

Ore grinding mills are heavy duty pieces of equipment that work 24 h a day in highly abrasive environments.From an economic point of view, it is important to keep these mills in operation and minimize the downtime for maintenance or repair, because a drop in production caused by a both scheduled and unscheduled stoppages lead to monetary losses.

A non-linear model-based control architecture for a single-stage grinding mill circuit closed with a hydrocyclone is proposed. The control architecture aims to achieve independent control of circuit throughput and product quality, and consists of a non-linear model predictive controller for grinding mill circuit control, and a dynamic inversion controller to control the fast sump dynamics.
