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 8hour shift ......
Mill power draw models
The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models. Models of this type do not predict the particle size distribution of a milled product — the more ......

Plant performance improvements
of the circulating load ratio (solids tonnage through the mill vs. the circuit) in determining circuit productivity was demonstrated by Davis (1925) and published by Gaudin (1939), as shown in Fig. 2. The circuit production rate increases with increased circulating load ratio, rapidly so at first and continuing to increase more gradually with higher circulating load ratio. The underlying cause ......

FREDA REBECCA SAGMILLING CIRCUIT OPTIMIZATION
It was also observed from the plant survey that there was a high re circulating load of fine material to the SAG mill amounting to t/h affecting mill capacity as this took space and limited the capacity for new feed. Using ModSim simulator, incorporation of a 100 micron screen on the cyclone underflow stream was simulated. The main purpose of the screen is to reduce the re circulating ......
