Accordingly the empty volume of the tube was filled with the same size (0.4–0.6 mm) Zirconia beads as a grinding media to comminute the cement particle. As the bead mill is a type of the stirring mill therefore abrasive and shear forces were produced by the mill as grinding force to comminute the cement

The total wear of grinding media during the cement clinker (balls of forging steel and hardened with 600 Brinell and cylpebs by special iron) is of 162308 g/t of cement (4.48.4 g/kWh) 2 . The presented values show a rapid wear of grinding media which leads to the diminution of specific charge with negative effects on grinding

Slag is the collection of compounds that are removed. In many smelting processes oxides are introduced to control the slag chemistry assisting in the removal of impurities and protecting the furnace refractory lining from excessive wear. In this case the slag is termed synthetic.
