ball mills gravity

Gravity is usually used to drain a ball mill but air pressure can be added to assist the draining for higher viscosity dispersions Material usually remains on the mill walls and on the media surfaces The residues can be washed out and thrown away constituting a yield loss Sometimes a specific amount of solvent is added the mill is closed
