Circulation of material occurs in several parts of a mineral processing flowsheet, in grinding and flotation circuits, for example, as well as the crushing stage. In the present context, the circulating load ( C ) is the mass of coarse material returned from the screen to the crusher relative to the circuit final product (or fresh feed to the

Summary: To achieve an optimum performance out of a closed circuit grinding system, the correct density regime of the hydrocyclones is of utmost importance and has to be adjusted to each systems´ requirement. One of the most important relationships for the optimization of the hydrocyclone recovery is the knowledge that the viscosity of the slurry increases with decreasing circulating load.

MINERAL PROCESSING FORMULAS. 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. The term “circulating load” is defined as the tonnage

Cytec Handbook. Why have a large circulation load:. If a product all finer than a certain critical size is required, the capacity of the ball mill is increased considerably by using it in closed circuit with a classifier and this increase is made still greater by increasing the circulating load in between the ball mill and the classifier (Fig. 70).
