Реферат

The comparison of kinetic of crushing in rod and ball mills has been realized on the two samples of copper-nickel ores. The products with different crushing time have been compared on granulometric composition, copper and nickel content in grain-size category. The criteria for estimation of crushing selectivity on chosen elements has been proposed. It has been shown that ore has been crushed in rod mill faster than in ball mill and with smaller overgrinding. Disintegration has been happened more selectively in ball mill.
Ключевые слова Crushing, granulometric composition, grain-size category, crushing selectivity, ball mill, rod mil, copper, nickel.
