Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition. The process is continuously repeated as the particles move by mass and volume action through the mill. Dry and wet grinding common.

Dry grinding – when subsequent concentration process is dry ( concentrating ores of Cr, Au, Pb, Mn, Mo, coal..). Wet Grinding – Normally used in mineral dressing ( subsequent concentration processes - flotation, leaching etc are wet processes ). 81 76. DRY GRINDING. 1. Feed material should have low ( < 1 % ) moisture content. 2.

1.2 Ores and Minerals. Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue ...

Mar 01, 2021 · This process is called comminution and involves dry crushing followed by dry or wet grinding of minerals. Some ore, like that found in placer deposits, does not require crushing, as it is already in small pieces. Most ore, however, is contained within hard rock that requires heavy duty crushing.

Industrially, wet grinding is preferred to dry grinding, among others owing to downstream processing requirements, as well as the higher energy efficiency associated with wet grinding. Wet grinding proceeds with the preferential formation of new surfaces and little bulk deformation in the particles.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

High Pressure Grinding Rolls are generally thought to only be effective in controlled "dry" grinding applications, however (depending on the material saturation level) they can readily process minerals well above 10% moisture. This gives HPGR's the flexibility to fit into a wide array of applications with both wet and dry classification.
