copper ore vibratory grinding high com mills
Vibratory mills consist of cylindrical or trough-like elastically suspended grinding pipes, which by means of a balanced mass system, are excited to circular vibrations with accelerations Rω 2 (R the radius of the vibratory circle of motion and ω the angular velocity of the unbalanced mass) of up to approximately 10 g — rarely above that.Abstract An analysis of flowsheets for processing sulfide and oxide copper ores, reagent modes, processing equipment, and flotation indicators in some domestic and foreign processing plants and productions is carried out. Autogenous and semiautogenous mills are commonly used in the primary grinding stage in ore processing plants, which Current Status of Copper-Ore Processing: A Review
