• Most companies ball mill their glazes and for good reason. It is not uncommon to mill glazes up to 12 hours. Blisters and surface imperfections are often caused by impurity particles in the glaze layer itself, grinding these down as small as possible will minimize the ability of individual ones to cause problems.
RETSCH solved this problem by creating an innovative integrated watercooling system. Grinding breaks for cooling, which are unavoidable in conventional ball mills even after only 30 minutes grinding at moderate speed, are usually not necessary when using the High Energy Ball Mill Emax.
