Grinding medium is an energy carrier in the mill that crushes materials by its own impact and grinding force. The most commonly used grinding media are spherical media and rod media. In some cases, irregular shapes such as round tables, cylindrical balls, short round bars, etc. are used, which are called special-shaped media.

Schematic drawing of an attrition ball mill. The attrition mill agitator rotates at speeds ranging from 60 rpm for production units to 300 rpm for laboratory units and uses media that range from 3 to 6 mm while ball mills use large grinding media, usually 12 mm or larger, and run at low rotational speeds of 10–50 rpm.

Millpebs have been used as grinding media to achieve fine grinding in ball mills. These are 5- to 12-mm spherical or oblong cast steel pellets, charged into ball mills as a replacement of, or in addition to, balls. While Millpebs can give significantly lower energy use when grinding to finer sizes, they also can lead to high fines

INTRODUCTION Stirred mill technology dates back to 1928 where the idea to use "an agitator and spherical grinding media" was presented (Stehr, 1988). The year 1948 saw the successful application of Du Pont's "sand mill" for pigment grinding. Subsequent years have led to the development of different types of

1. Introduction. Galena is a primary source of lead, which is often recovered by flotation. Galena needs to be ground before flotation. Galvanic interaction will occur when the grinding medium contacts with galena because of the semiconductor properties of galena, which will affect the flotation electrochemical behavior of galena .The galvanic interaction has a significant effect on the ...
