benefits of circulating load. Figure 2. Effect of circulating load and classification efficiency on milling circuit capacity [10] 2. Mathematical model ¨ The grinding kinetics in the ball mill follows first order grinding law which states that the rate of production of fines (D) is
Product from the mill exits the tank through a stand pipe and then to the cyclone sump. The slightly coarser portion of the mill overflow is recycled back into the bottom of the Vertimill®. The recycle system can reduce cyclone circulating load by allowing the mill to preferentially grind the coarser material.
