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).

Take, for example, the rock crushing system inherent to the mining process. A known issue for some gyratory crushers is the tendency for the inlet pit to be overwhelmed by material. When too many rocks fill the pit before they can be fed passively into the crusher, the rocks interlock and create blockages.
