Circuit production rate of new fine material (t/h) = Total mill power (kW) x CSE (%) x Mill grinding rate of coarse material (t/kWh) (2) Production rate, mill power and CSE can be measured during a plant circuit survey. The mill grinding rate of coarse material is then calculated. At the circuit target P80 size, this

Recommendations for achieve these goals in ball mill grinding circuit: In a plant with hydrocyclones is correct to use higher circulating load (~400%) to diminish residence time in the mill. For instance, versus 300% CL around 5% energy saving is obtained and the product has 5%-10% less -10um fraction (see 4th Grinding and Classification Law)
