The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. Get Price
2021-4-11 · Ceramic grinding media for mining industryCeramic . 2021-1-14 Many mining industry production uses ordinary ball mills, using steel ball grinding media, low grinding efficiency, product particle size does not reach the monomer dissociation fineness, so in the field of metal mine and non-metal minerals, it needs to have regrind or fine grinding and energy saving, use sand mill and tower
A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix. Cited by: 13 Calculate Top Ball Size of Grinding Media Equation & Method. An online calculator lets you calculate Top Ball Size of Grinding Media for your mill.
Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge.
