Wet-Grinding Mills SpringerLink

In this chapter the mechanisms of wet-grinding mills are considered. The nature of the forces at work, together with a detailed consideration of their interplay and means of control, are discussed in Chapter 6. The general term “tumbling mill” includes the rod mill, pebble mill, and ball mill.

An investigation of wet grinding in a laboratory

Batch breakage kinetic tests were performed in a mill of 0.3 m diameter for a range of mill conditions. Accurate simulation required the measurement and use of factors which accelerated the specific rates of breakage of the top sizes as finer material accumulated in the slurry. These factors depended on the size distribution expressed relative to the top size, not the absolute size, suggesting
