We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill.

For 2 chambers mill All these calculators are reliable, but Users need a certain experience to implement results of these calculators . Sizing equipments and mill's optimization are the job of material suppliers and experienced engineering offices.

) is calculated by difference of the total and ball charge fractions, see Equation (11). J r J t J b (11) A residual can be constructed for each powerdraw and weight measurement. Both residuals can be reduced to equations in total (J t) and ball (J b) charge fractions. Solution for the two unknown charge

The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm. For the efficient use of rods it is necessary that they operate parallel to the central axis and the body of the mill.

Big dry grinding ball mills are often two-compartment mills, with big balls in the first compartment and small balls or cylpebs in the second one. An extra grate wall is used to separate the two charges. The temperature can increase considerably in dry grinding mills, and rubber lining should not be considered.
