Looking at dry grinding material of extreme hardness holding a BWi of 27kWh/t from an F80 of 6-8mm to a P80 of 16um in an air-swept compartmented ball mill. There are operating plants doing this to 75um, is 16um too fine? Only considering milling technologies due to project requirements. Any experie
F.L. has developed this cement grinding system which is a fully air-swept ring roller mill with internal conveying and grit separation. This mill is a major improvement of the cement grinding systems known today which are ball mill, roller press (HPGR)/ball mill, vertical roller mill and closed-circuit roller press for finish grinding.

The ball mill is 13-ft-6-in diameter by 18-ft, and was originally intended for a rod mill application. It has a large diameter trunnion and an oversized motor. To bring the ball mill speed up to 75% of critical from 66%, the 24-tooth pinion was replaced with a 27-tooth one. Equipment selection using SPI data was deemed a success.
Abstract. Fine-particle HMX powders are of interest for a variety of applications in Department of Energy weapons programs. A process is described for producing these materials in two stages: first, precipitation to yield a relatively coarse, free-flowing product of the desired polymorph, followed by dry grinding in a fluid energy mill using air as the working fluid.

This means that this modeling approach is a useful quantitative indication of what may occur in fully air swept mills. With more data set taken from the plants it would be possible to develop the relations between the model parameters and the mill operating conditions such as ball size distribution, mill load and grinding circuit configuration. 6.
