Geometry of the cone crusher. The cone crusher consists of a concave that provides the outer surface constraining the particles and a mantle or cone which is inside the concave, see Briggs, 1997, Evertsson, 2000 for a more detailed background of cone crushers. Fig. 2 shows an annotated diagram of one such cone crusher.

In many mining applications there is also a grinding step. A common type of machine used as secondary and tertiary crushers, is the cone crusher. Previous research (Evertsson, 2000; Gauldie, 1953) has made it possible to model the behaviour of a given cone crusher. The geometry of the crushing chamber is crucial for the performance.

The cone crusher is a modified gyratory crusher, and accordingly many of the same terms including gape, set, and throw, apply. 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 6.8).Major suppliers of cone …

Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).
