Grinding > Calcite Grinding Mill - IndustryArena

Calcite is a common calcium carbonate mineral, which is easy to grind its 3 Mohs hardness. It can be used as a raw material in the silicate industry. Generally, the grinding of calcite requires a large grid of finished products, i.e., an extreme grinding fineness is required. Thus, the ultra-fine grinding machine is commonly used for calcite grinding.

Bond Work Index - an overview | ScienceDirect Topics

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, …
