For close circuit the product is screened with a mesh size much less than the set.

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.
