# calculating circulating load crushing circuits

• Circulating load estimation in closed circuits. At each iteration the circulating load CL is calculated using the following equation f i is the flow volumetric or mass which feeds the i th unit operation unit that contributes directly to the circulating load p i is the flow partition in the same unit operation calculated according to the unit operation and its operational parameters.
