The mill discharge model allows the calculation of the recirculating load (RCL) which enables the full definition of the primary circuit mass balance which allows for monitoring, control and optimisation of the prevailing operating conditions. 8.3. Mill fresh feedGood estimates of SAG mill fresh feed rate and size distribution are possible.

Recirculating load is the fraction of mass flowing through the mill divided by the feed throughput, and this has been found to be a significant consideration in mill circuit performance, and thus the economics of the operation. This paper will describe a digital tool and methodology that can, once calibrated to a baseline, be employed to ...

These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a single-stage milling application to a semi autogenous ball-mill-crushing circuit, and the application is well described. This refers to high-aspect AG/SAG mills. Ball Charge Motion inside a SAG Mill. With a higher density mill charge.

Calculate the CSE as the average: (80.7 + 73.5) ÷ 2 = 77.1% + 75 μ. In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. This means that 77.1 per cent of the particles in the mill are 'coarse' and that 77.1 per cent of the mill power is being used 'effectively'.
