The primary task of the coarse crusher is to make it possible to transport the material on a conveyor belt. In most aggregate crushing plants, primary crushing is performed in a jaw crusher, although a rotary primary crusher can also be used. Impact crushers may also be the best choice if the material is easily crushed and not excessively worn.

Cone Crushers - McLanahan

A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4" closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches. Reduction ratios of 8:1 may be possible in certain coarse crushing applications.
