Guidelines - Jyoti Ceramic Industries Pvt. Ltd.

Calculation of Media Load. Ex: Bead mill net volume capacity is 50 ltr. charging with Dia.1.7-2.4 mm beads. For vertical closed type mill it works out to=35 ltr. (70% of mill vol) x 3.95 kg/ltr. (Packing density of Zirconox beads). That is 138 kg. Zirconox micro bead charge required for a 50 ltr. capacity closed vertical mill.
