First comprehensive investigations on grinding in stirred media mills were performed by Stehr (1984) and Weit (1987). These investigations show that the comminution progress mainly depends on the specific energy input E m, which is the total energy supplied to the grinding chamber related to …

A wide range of grinding media types are used in stirred mills, however in the minerals industry the decision is usually driven by cost which has led to the use of coarse sand, granulated slag and sized ore. A common problem with low grade sand media is that it has internal flaws and tends to break rapidly.

Therefore, the optimization of zeolite grinding, as well as the control of its properties are of a great importance. In the present paper a Hungarian natural zeolite was mechanically activated in stirred media mill for various residence times in distilled water, meanwhile the particle size distribution and the grinding energy were measured.

Abstract The mills traditionally used for wet ultra-fine grinding are high-speed stirred ball mills. The aim of the research was to investigate the influence of the solid (limestone) concentration and of the concentration of sodium polyacrylate on the apparent viscosity and the grinding efficiency. With increasing solid concentration the energy utilisation initially increases up to a maximum ...
