Steel balls of 5, 8, and 15 mm diameter were used as the grinding media, in a ratio of 3:5:2. Each grinding was performed with 60 g of feldspar in a 500-mL steel can containing 600 g of hardened steel balls. In each grinding run, the feldspar samples were ground for periods ranging from 10 to 200 min.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

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 saves over 20 …

Ceramic ball mill is also called intermittent ball mill/ batch ball mill, intermittent operation of the dry and wet for the fine grinding of feldspar, quartz, clay, ore and other raw materials. Batch type ball mill (ceramic ball) is mainly used for mixing of the material, grinding, the fineness of the product is uniform, saving power. Both dry grinding, wet grinding can also be.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of …
