wet ball milling safety

Ball mills are slow compared to other methods of grinding, it could takes hours, for example, to grind all the particles in a clay to minus 200 mesh. In fact, if mica or other flat particles exist it may be practically impossible to grind them to minus 200, for this reason ball milling is normally done in consort with wet screening.
