Section snippets Mathematical model. In a series of open circuit tests reported by Dorr and Anable (1934) limestone was ground at various feed rates in a 3 ft ball mill.The production of fine material (final product) increased with increased feed rate, and the relationship is a straight line in log–log space.

Abstract: In order to achieve satisfactory performance in controlling complex process operation in the presence of heavy disturbances and large uncertainties, equivalent input disturbance (EID) approach is used to design the controller of ball mill grinding process. EID estimates an equivalent disturbance of grinding circuit on the control input channel, …

Introduction. Tube mills having multi-chambers are traditionally used for cement grinding either in open or closed circuit operations. In the first chamber, larger balls (100–60 mm) are used for coarse grinding while the smaller balls (40–15 mm) are used for fine grinding.The chambers are separated by an intermediate diaphragm which allows …

DESCRIPTION: Flotation followed by shaker table concentration in open circuit grinding. ORE TREATED: When the mineral in an ore is freed at a coarse mesh, this flowsheet gives high recovery and high capacity. The practice is limited in scope, as on ores requiring fine grinding, closed circuit is preferable, and on ores wherein the gold is free, …

Given that mills are charged to the target ball charge with reasonably sized media, and the feed to the ball-mill circuit is not so coarse as to cause constant scatting, the key to efficient ball-mill circuit operation is efficient classifier operation. The standard classifier for ball-mill circuits is the hydrocyclone.
