These tests were done with a 0.82 x 1 m grate discharge mill with a 30 mm graded ball charge and a 30 filling degree. The mill discharge pulp density was increased from 68.8 to 75.9 solids. The data is summarized in Table III. The example in Table III illustrates that the density has a large influence on the grinding efficiency. In this ...
Jan 01, 2016 The capacity of a ball mill depends on its dimensions, the type of mill overflow or grate discharge, the speed at which the mill rotates, the mill loading, the product size required from a given feed size, the work index, the mill shaft power and specific gravity of the rock.
That is to say that the combined effect of the lateral projection or initial velocity and gravity is to cause the more or less scattered particles to take the path diagrammatically shown at FIGURE 312, or something similar to it. ...
