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.
Optimization of continuous ball mills used for finish-grinding …
The L/D ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15%, 20% and 25%. The experiments clearly indicated that the optimal L/D ratio and the optimal ball charge filling ratio are different for each feed fineness.

Raw milling and blending – INFINITY FOR CEMENT EQUIPMENT
Continuous blending involves simultaneous feeding of the silo, overflow to a second silo and final discharge to kiln feed. Modern equipment generally uses continuous CF silos, each having capacity of more than 24-hours' kiln feed and yielding a blending ratio (or 'blending factor') of 4-8, or around 2-3 for older silos.
