### Circulating Load Calculation Formula

Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift allowing to calculate corresponding to circulating load If a ball mill uses little or no water during grinding it is a dry mill. If a ball mill uses water during grinding it is a wet mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.

### Ball Millsan overview ScienceDirect Topics

Ball mills are filled up to 40 with steel balls (with 30–80 mm diameter) which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture. Jul 01 2003 · The specific flow rate is the ratio of the maximum flow rate to the chamber volume. The higher the specific flow rate the more efficient recirculation grinding is expected. Conclusion With a better grasp on the theories behind high-performance media mills the process of determining the best media mill for your application will not be so painful.
