Choke Feeding a Jaw Crusher | What is Choke Feed Looks Like

Here is what a well choke fed jaw crusher looks like! Too many mines run these jaw crusher cavity like a funnel without any choking. Operators must keep the jaw’s cavity full to maximize rock-on-rock compression and crushing. Notice the shape of the liner profiles? A crusher is choke fed when the chamber is full and there is material above to keep it full. This contrasts with regulated feed

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.

As with other compression crushers, the cone crusher yields a somewhat elongated and slivery particle shape. This may be minimized, however, by "choke" feeding the crusher. This technique will also make the shape and size more uniform. One way to choke feed is with a surge hopper and a controlled belt-feed to the cone crusher (Figure 5-10).
