The ratio of moisture to solids is important in ball mill work. From actual operation it has been observed that fine grinding is best done when water constitutes 33 to 40 per cent, of the pulp, or the waterto solids ratio is 1 : 2 or 1 : 1½. Where a minimum of fine material is desired, 50 per cent, and upward of water is desirable.
