Feb 14, 2018 A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls,flint pebbles

The mill is filled with different amounts of steel balls, rocks and water. The water and rock mass are kept constant respectively at 86 kg and 259 kg for all the tests; this corresponds to a rock proportion of 15% of the total volume inside the mill. Only two parameters are varied in this study: the mill rotational speed and the ball filling

Transcribed image text: The ball mill (detailed in Figure 1 below) comprises of large drum (1m in diameter and 1.3m long) that is partially filled with rock and steel balls, and as the drum rotates the steel balls impact the rock to grind it down into smaller pieces. The mill is situated in a remote location, where the ambient temperature can be as high as 50 C, and in the direct sunlight the
