The first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills. Figure 1. The first example is a comparison of two parallel mills from a daily operating report. Mill size 5.03m x 6.1m (16.5′ x 20′ with a ID of 16′). This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power ...

Ball Mill The Ball Mill is widely used in the fields of building materials, mineral processing, chemical industry, electricity, etc. It can grind ores or other materials with certain granularity into fine powder. 0086-371-63769782 [email protected]

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
