Our results suggest that integrating an air classifier into an open-circuit ball mill can increase the production rate by 15% or increase the cement-specific surface area by 13%. A single-compartment mill entails a pre-milled feed for proper operation, whereas a two-compartment mill yields a finer cement product than a three-compartment mill.

This conclusion was drawn from a series of tests in which Portland cement was ground either conventionally in a ball mill or in high-pressure grinding rolls. The water demand of the ball milled cement was 27 per cent and of the high-pressure ground cement was 32.5 per cent, at the same specific surface area (350 m 2 /kg).
