Grinding control strategy on the conventional milling

If the hardness of the ore increases, the particle size in the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio, and hence the control loop will add more water to keep the ratio constant. However, the amount of slurry reporting as fresh feed to the second milling circuit
