The jaw crusher, because of its box-frame construction, and simple toggle mechanism, is especially well adapted to extra heavy design for the crushing of extremely tough materials: in this respect it holds some advantage over the gyratory type, because the extra strength necessary for such work can be built into it at less cost than is required ...

The cone crusher (Fig. 13.12) is very similar to the gyratory type, except that it has a much shorter spindle with a larger-diameter crushing surface relative to its vertical dimension. The spindle is not suspended as in the gyratory crusher. The eccentric motion of the inner crushing cone is similar to that of the gyratory crusher.

A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.

4. Gyratory Crushers. Gyratory crushers are used in the mining industry to crush ore and rock. They work by applying a downward force on the material, causing it to be crushed between the mantle and concave. These crushers have a higher capacity than jaw crushers, but require more maintenance and are less efficient. Importance of …

Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.

Cone crushers: Cone crushers also work with the compression method, similar to the gyratory crusher. This kind of crusher contains a rotating mantle and a concave surface. It can accept dry or wet feeds depending on the material. Impact crushers: Impact crushers are used with less abrasive rocks. They use impact forces …
