THE INFLUENCE OF MILL SPEED AND PULP DENSITY ON THE GRINDING EFFICIENCY 89 mill discharge density (before dilution) obtained during the sampling. The ball charge, and hence the volume of the voids These data are then used to calculate the total pulp and ball charge angle (see Graph 5).

From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below 0.75 mm), followed by a tube mill for fine grinding. Typically the ball mill was placed on an upper floor so that material could move by gravity.
