a given charge volume, about 25% more grinding media surface area is available for size reduction when charged with Cylpebs, but the mill would also draw more power. 3. Laboratory tests As the objective of this study was to predict the grind-ing performance of Cylpebs in a full-scale ball mill, a model-based procedure for scale-up of ball mill was

Conventional ball mills are usually limited to a particle size of 1µ after one hour of grinding since gravity causes the particles to fall out of the grinding zone (between the media). Milling can be done either wet or dry, although it is generally possible to get smaller particle sizes wet than dry.
