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.

The dependence of the temperature of the finished cement on the volume of fresh air is obtained by the example of a closed circuit cement ball mill of the Belgorod cement plant. View Show abstract

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.

The ball mill sat at a slight angle, to compensate for the large intake than discharge diameter. That was an added feature, when I discovered the original small intake was problematic. For the record, lime was introduced to the ball mill on a regular basis, to insure that the pH was higher than 9½.

Cement mill (Ball Mill) consists mainly of : - A rotation steel cylindrical shell supported at both ends on turning /. slide shoe bearings. - Liners for protecting the inside surface of the shell. - Diaphragms for dividing the mill into two or more compartments. - Grinding Balls. - Mill cooling system.
