Gyratory crushers may seem like complex machines, but their principle of operation is surprisingly straightforward. At its core, a gyratory crusher consists of a mantle that rotates within a concave bowl-shaped housing. As the mantle gyrates, it creates a crushing action by compressing the rock against the stationary concave walls.

Cone crushers and jaw crushers both work by compression, reducing materials by squeezing them until they break apart. The benefit that cone crushers offer over jaw crushers is their ability to output a more cubical product similar to impact crushers. Cone crushers have traditionally been used as secondary and sometimes tertiary crushing ...

The cone crusher is a modified gyratory crusher. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone (Figure 8.2). Power is transmitted from the source to the countershaft to a V-belt or direct drive.
