If you make BP then precrumble your charcoal to (say) 20 mesh then weigh batches out. Add some minutes in the mill if needed to let the mill do the milling with the lid closed. IMO (and only that) charcoal should be made and crumbled to about 10 mesh then packed for storage til needed, certainly keeping fine powders is likely to promote mess.

The rotational speed of the milling jar should be ~65% of the critical speed of the jar. The critical speed is 'the speed when a ball mill becomes a centrifuge' and may be calculated for a specific jar and ball diameters as follows: CS[rpm] = 2676 / SQR( JarID[mm]-BallOD[mm] ).

GSI's ball mills are housed with oversized roller bearings and a complete drive system discharging mesh sizes from ~40M to <200M. The capacity, or throughput, of our GSI ball mills are directly linked to the particle size of the ball mill discharge. For instance, it is roughly 3 times as fast to reach a 65 mesh grind than a 200 mesh grind.

As the rotation speed of the high-speed vibrating ball mill was not adjustable, the factory default setting of 1200 r/min was used. It is generally believed that the ball mill has good grinding efficiency when the interstitial filling fraction of the material is 0.6-1.2 [49, 50]. The parameter setting of the ball mill is shown in Table 1.
