Jaw Crushers - McLanahan

As a rule, Jaw Crushers have a 6:1 or 8:1 ratio for crushing material. Still using the 32 x 54 Jaw Crusher example, the top size of the feed entering the crushing chamber has to follow the F80 rule that 80% of the top size feed material is smaller than the gape opening. Using the F80 rule with the 32 x 54 Jaw Crusher, the 32" gape opening equals a 26" top sized feed, and with the …

Impact crushers tend to be less expensive than compression crushers (aka cone and jaw crushers, which we already covered) and have a higher reduction ratio. They can also break sedimentary deposit-type rocks—limestone and similar—along natural lines, which rounds off sharp angles and weak edges. This can produce a result that is more sand-like in nature.
