2021-5-4 They can be used for both plant and test mill data. The cumulative grinding rate through the size of interest is the identical parameter as the ball mill grinding rate calculated from the functional performance equation. Its maximization is the technical optimization criterion for ball sizing studies.

2018-12-17 The nearby cement plant operates with 20 mins retention time for clinker grinding in the ball mill 70 Ton hold up. Power consumption = kW = 7.5 x Gw x D0.5 = 7.5 x 163 x 3.80.5 = 2383 kW. (Check its correctness) (13) Grinding energy = 30-35 kWh / Ton cement . Here, Gw = ball charge, ( Ton ); and D = Effective mill diameter, ( m ).

2020-6-23 A ball mill is one of the most common equipment items in a mineral processing plant. Its job, to grind rock by tumbling it in a large metal cylinder loaded with steel balls, is highly energy intensive. In fact, the cost of grinding in a mining operation represents a significant proportion of the total energy cost.
