Impact crushers. An impact crusher uses mass and velocity to break down feed material. First, the feed material is reduced as it enters the crusher and makes contact with the rotating blow bars or hammers in the rotor. Secondary breakage then occurs as the material is accelerated into the stationary aprons or breaker plates.

The gyratory crusher has capacities starting from 1200 to above 5000 t/h. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be …

A crusher is choke fed when the chamber is full and there is material above to keep it full. This contrasts with regulated feed, where the flow of material to the crusher is throttled in some manner so that the crusher is never completely filled. Aa particle moves from level to level it drops a greater distance with each movement of the mantle.

13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.

In mining, the most important criteria for effective crushing of ores is to choose the type of crusher that suits the rock (ore) material, and to ensure uniform feed. Gyratory crushers …
