Ball Mill - an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Black Powder – GardenBallistics

2015-3-14  Making black powder is more complex than simply mixing the three ingredients together. This is in fact called green powder or polverone which burns slowly and inefficiently leaving lots of un-burnt solids behind. Proper black powder is mixed thoroughly to a fine powder using a ball mill or with other non-sparking grinding media.
