Computation of charging media for a double compartment cement ball mill

The charge of grinding media for two-compartment ball mill can be calculated for dry grinding of cement raw mix. The medium-hard raw material for the mill feed has a particle size range of 0.5 to 25 mm. The mill dimensions are: -. Inner diameter of mill = 4.2 m. Length of drum = 15.25–1.0 = 14.25 m.

How Coarse can Ball Mill Feed be

(The crushing plant runs 11 h per day, the mill 24 h/d.) The mill power (and media consumption) is higher and the mill grinding length is a bit longer in the open case. Is there any other side-effects associated with feeding a ball mill with 16 kW-h/tonne feed which is coarser (closed P80 of 13.4 mm vs. open P80 of 15.4 mm i.e.2 mm coarser)?
