Large bevel gears drive the crushing machines used to process ores and minerals in the hard-rock mining and aggregates industries. Among the most common machines of this type are gyratory (Fig. 1) crushers and cone crushers (Fig. 2). The gyratory crusher is typically the first process step after initial blasting at the mine, or quarry, with the ...

Impact crushers are traditionally classified into two main types, horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.

The most common crushers in crushing sites and industries are gyratory, jaw, roll, and cone crushers . The crushing force in jaw crushers is applied through the elliptical motion of the moving jaw, which crushes the particles against a fixed jaw plate . The charge material is fed into the crusher through the gape at the top of the crusher.
