How to decrease particle size of alumina powder with ball

All Answers ( 10) Water is usually used as the solvent (only with materials susceptible to easy hydration the alcohol is used) and the amount of water to be used depends on the density of the desired final suspension, but is usually between 20-25% of the useful volume of the mill. In practice the mill after charging should have about 25% of its free useful volume.
