• How a Grate Discharge Ball Mill Works911 Metallurgist

     · A grate discharge mill that is "ground-out" would show the desired near zero blinding. The slots in the early grates were designed around the traditional types found in proven concepts of metal grates. Typically a slot (fig. 2) was designed with a selected rectangular circular or square opening and then tapered out in all directions to
