The GP7 secondary gyratory crusher features a large feed opening of 18 in. (450 mm), which remains constant throughout the lifetime of the liners.
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).
