Planetary Ball Mill PM 300 Wet and nano-scale grinding with the PM 300 . Wet grinding is used to obtain particle sizes below 5 µm, as small particles tend to get charged on their surfaces and agglomerate, which makes further grinding in dry mode difficult. By adding a liquid or dispersant the particles can be kept separated.

— The discussions in Section 2 for dry mills can also be applied to the wet mills up to the point just before the balls reach the pulp surface at point (x 1, y 1). See Fig. 3 for the ball movement curve in the pulp of a wet mill. Download: Download full-size image; Fig. 3. The ball movement in the pulp in a wet mill.
— Wet ball milling is more adept at generating smaller and dispersed biochar particles than dry ball milling [31]. Wet ball milling composite of ZVI and Fe 3 O 4 showed a splendid synergy in electron storage and electron transfer [32]. The sulfide solution is effective in minimizing ZVI oxidation during wet milling [14].

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
