A crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.

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 …

The working principle of primary crushers varies depending on the type of crusher, but generally, they work by reducing the size of the material through compression or impact. In jaw crushers, the material is fed into the crushing chamber and is crushed between a fixed jaw and a movable jaw. Gyratory crushers work by crushing materials …
