The performance of the mill is influenced by the quantity and quality of the circulating load being returned to the mill. The performance of the cyclone is influenced by the particle size distribution of the mill discharge. The net result of the unit operation is a reduction in size of the new feed tonnage from a prescribed top size to a ...

A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.

Calculation of Circulating Load in a Classifier. A mechanical classifier often receives its feed from a ball mill and produces (1) finished material which overflows to the next operation and (2) sand which returns to the mill for further size-reduction.
lation of the circulating load was achieved. At each iteration, the circulating load CL is calculated using the following equation: CL=∑. n i=1 (p. i.f. i ) (2) Where fi is the flow (voul metric or mass) which feeds the i-th unit, an operational unit that contributes directly to the circulating load and pi is the flow partition in the same unit
The width of the chip is largest at the point of entry and grdualy gets smaller, until it is zero at the point of exit. The chip load is the maximum value. A related term is Average Chip thickness which is used for force and power calculations. Chip Load Chart – Inch Chip Load in IPT per Milling Cutter Diameter and workpiece material
