A container has two compartments connected by a small tube of negligible volume. The tube has a valve that permits the two compartments to be isolated from each other. The volume of the left compartment is 3.0 L and is filled with 2.0 atm of Ar. The volume of the right compartment is 4.0 L and is filled with 0.5 atm of N2O.

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.

Pebble Mill Grinding. Essentially tube mills and pebble mills may be considered as ball mills, the basic difference being that the ratio of length to diameter is greater. Usually the shell length is between 2 and 5 times the diameter. These mills are primarily used to grind various materials to 100 mesh and finer.

The size reduction takes place in a two- compartment tube mill; the first compartment of the mill is shorter than the second compartment. The coarse clinker is ground in the first compartment where larger balls (80, 60, 50 mm) are used and the fine grinding is done in the second compartment where smaller balls (below 25 mm) are used.
