Producing such a fine crush generally requires multiple crushing stations of up to 4 being but as a minimum of 2 being oversized. The gape determines the maximum size of material that can be accepted. Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4

Feeding impact crushers. Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with your feed. The initial impact is responsible for more than 60 percent of the crushing action, with the remainder made up of impact against an adjustable breaker bar and a small amount of inter-particle

Crushing is accomplished by compression of the ore against a rigid surface or by impact against a surface in a rigidly constrained motion path. Crushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers.

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.

“In a crusher, the crushing chamber is going around in a circle and the crusher is closing up in one location,” Dobler says. “Once you have segregation in that chamber, one side is coarse and the other is fine. Over time your components will feel that, and they will fail.” The same logic applies to impact crushers, Dobler adds.
