1. Introduction. Ball mills are one of the most common industrial equipments for reducing the size of particulate systems in various fields such as cement industry, minerals or nuclear fuel production [1].In such equipment, the powder is ground due to the movement of the grinding media, also called pebbles, within a rotating vessel.

Steatite ceramic balls and mill lining bricks are manufactured from the same fine-grained composite and are ideal performance partner. Thus, they retain their shape better and last longer than flint / river pebbles, natural stones, porcelain etc. Due to their higher density, hardness, toughness and a higher degree of sphericity, Steatite ceramic grinding media …

Filling of the mill with grinding balls was assumed to be 45% water capacity of the mill for full feed and 22.5% water capacity of the mill for half of the feed mass. Additionally, the ceramic body masses were ground with balls of changing composition. Mass fractions and dimensions of balls for every experimental series are given in Table 3.

In ceramic laboratories, ball mill is often carried out to mainly achieve a thoroughly mixed state of starting powders with initial average particle size (d 50) of 1–20 μm. In laboratories, a polyethylene-based small bottle container (nominal volume of approximately 250 ml) and zirconia balls with nominal diameter of approximately 1–10 …
