A New Macrophenomenological Concept of Comminution …

This paper presents a new approach to modelling ball mill grinding: The Operational Model. The theoretical aspects of the model as well as a comparison with existing ones are discussed. The concepts of the model, summarised in easy-to-operate PC programs, permit the calculation and design of new ball mills, and a critical evaluation and optimising of mills in operation.

Advanced comminution modelling: Part 2

Geometry of the dry ball mill used for predicting the wear evolution of the mill, (a) overall oblique view, (b) close-up of the belly lifters, and (c) close-up of the feed end. The mill rotation rate is 13.2 rpm which corresponds to 74.4% of critical speed based on an internal liner diameter of 5.68 m.
