## Ball Mill Circulating Load Mineral Processing & Metallurgy

09/10/2015 Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or classifier (classification system) are screened and the cumulative weight percentage retained is calculated for several mesh sizes to obtain the Ball Mill Circulating Load. The percentage through the smallest mesh can also be used to determine Rcl, as follows: The same as circulating load

21/02/2015 Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating load
