The mill uses a laboratory hammer-shaped ball mill, and 500 g of mineral samples and 300 g of water are uniformly taken each time with the slurry concentration being 62.5%. The fineness tests were carried out using steel balls of 8 different sizes in laboratory for different grinding periods.

Autogenous and Semi-Autogenous Mills. Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations. These mills typically have a large diameter relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media.

The range between 40 and 60 m/s is precisely of interest for operation of the special hammer mill, however. By means of tests, the factor may be determined to be: f = 0,4/v U 1,5. A constant peripheral speed of 55 m/s for fine comminution and 40 m/s for coarse comminution applies, irrespective of equipment size, as a design criterion.
