The product from an open-circuit primary rod mill receiving 160 tons/hour of new ore feed joins the product of a secondary ball mill flowing to a sump (a pump box) feeding a set of classifying hydrocyclones in a reversed closed circuit with the ball mill. The pulp densities of the samples taken from the circuit are as follows: Rod mill product stream: 62% solids by weight. Ball mill product stream: 70% solids by weight. Joined products stream: 67% solids by weight. Calculate the percent circulating load and the hourly circulating load tonnage.
