Grinding control strategy on the conventional milling circuit of . Circulating load control The only manipulated variable available in the closed milling circuit (ball mill 2) is the cyclone dilution water flow rate. Attempts to use this for density control were not successful.Optimization of mill performance by usingto the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to obtain regular measurements of the ball load .
