GRINDING BALLS. SPECIFIC GRAVITY OF STEEL

15/09/2016· Production of grinding balls is regulated by DSTU 8538: 2015 (DSTU 3499-97). Grinding steel balls for ball mills are made of carbon steel and / or stainless steel. Table 1 shows the specific gravity of carbon and alloy steel. The specific gravity of metal is a physical quantity defined as the ratio of the weight of metal to the volume it occupies.

With the above chart the per cent solids or specific gravity of a pulp can be determined for ores where gravities do not coincide with those in the Pulp Density Tables. This chart can also be used for determining the specific gravity of solids, specific gravity of pulps, or the per cent solids in pulp if any two of the three are known.

Flash Flotation with Closed Circuit Grinding

Flotation in Grinding Circuits Hydrocyclones are used in many grinding circuits to make a size separation which ideally sends the fine ore fraction to conventional flotation and the coarse fraction back to the mill for further grinding. The separation results not only from particle size but also from particle specific gravity. The result is a
