Maximum power is drawn by a mill when the charge occupies approximately 50% by volume. However, as seen in Figure 4, the power curve becomes very flat in the range above 45%. As a result, mills are seldom run with charge levels greater than 45%. In rod mills, the charge is swollen by particles of feed which separate the rods.

Mar 08, 2021  Because of this, rod mills are normally operated with a 32 to 40 percent charge by volume. In operation, this becomes a 40 to 50 percent charge, with a bulk density considerably lower than that of stacked rods. Ball mill charge becomes measurably swollen only when there is a buildup of large unground material in the ball mill or when the ...
