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).
