### Grinding Circuit - an overview | ScienceDirect Topics

Efficiency and Circulating Load 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 circuit), often quoted as a percentage.

Nov 18, 2014 · Circulating load calculate • E = Efficiency Screen % • R = Larger than mesh % • S = C.L. + new feed (t/h) • f = larger than mesh in feed % • C.L. = circulating load Slide 4 [2] 5.

Operating the crusher with a completely filled crushing chamber. Choking Stoppage of the flow of material through the crusher, which is usually due to the wet and sticky material clogging exit points. Circulating Load The amount of oversize material returned back to the crusher from a screen in a closed circuit crushing system.

### Closed crushing circuits with nomographs

Another equation proposed earlier (Allis-Chalmers, 1953; Flavel, 1977) gives the circulating load ratio Rg as a function of e and x, 1 1 x e Rg (2) where e is the % efficiency of the oversize removal, 100 x u is the percent oversize in the crusher discharge, and Rg is the circulating load ratio expressed as fraction of the new feed F. But, since 100 e r , Eq.

### Handbook of Crushing - TerraSource Global

type crushers have choke points, but this does not necessarily mean that choking is likely to occur. Choking — Stoppage of the flow of material through the crusher, usually the result of wet and sticky material clogging exit points. Circulating Load — The amount of oversize returned to the crusher from a screen in a closed-circuit system.
