This is an important consideration in cement clinker grinding. Capacity per unit of mill weight is greater, with a corresponding reduction in mill cost. A long mill will produce a high density, fine product in wet open circuit. Regardless of mill length, the larger diameter mill provides a greater weight of balls per unit of mill weight and ...

As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore. With these two weights formula (2) may be used to obtain K, and then formula (1) to convert to S, the specific gravity. A volumetric flask of one liter capacity provides the necessary accuracy.
