The disadvantage of this type of crusher, when high capacity is required, is the relatively small discharge width, limiting the capacity as compared with the discharge circuit of a gyratory crusher. Jaw crushers are mainly used in plants producing up to approximately 1600 t/h.

As a result, the product size distribution varies. When the feed drops into the crusher, the mantle squeezes the rock against the concave surface. When the mantle moves away and the rock drops down further and subject to additional crushing during the next cycle . Material exits the crusher through the open side setting.

The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.

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

In an aggregate crushing plant, the crusher performances will be affected by the variation from the incoming feed size distribution. Collecting accurate measurements of the size distribution on the conveyors can help both operators and control systems to make the right decisions in order to reduce overall power consumption and avoid undesirable operating conditions.

Optimum fragmentation size may not be the required size but knowing the size distribution for blast and rock mass conditions, the contractor can adapt the blasting if possible [2]. For prediction of the fragmentation size after blasting the Kuz-Ram model is generally used.
