· The pilot mill is also equipped with a sensor measuring the ball and pulp toe and shoulder angles (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73 solids as the total media angle does not change.

Chat Online### Effect of ball size and powder loading on the milling

· The ball diameter of 5 mm is optimal at 50 rpm of rotation speed (the resultant average particle size of the milled powder is 2.3 μm) ball diameter of 3 mm is optimal at 100 rpm (1.4 μm) and 2 mm is optimal at 153 rpm (0.84 μm). From this result it can be said that the optimal ball size for efficient milling decreases with the rotation speed of the mill.
