Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (5-8 mm range) improves grinding energy efficiency up to 50% using stirred mills.

Cement mills Question 2. What would be the recommended ball charge and combination to produce masonry cement at 6000 cm 2 /g. the component percentage are clinker= 50 per cent, limestone=45 per cent, gypsum=5 per cent. I tried researching on this, but the suggested ball charge and combination would always refer to OPC at 3000-3200cm 2 /g.
mill grinding rate over the material's grindability as measured in the lab. Mill percent solids optimization has thusly been achieved (McIvor et al., 2000). For media sizing, maximizing the mill grinding rate on a given ore is equivalent to maximizing the mill grinding efficiency. Ores of different grindability will be part of the discussion.

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.
