The material you feed into the machine must be pre-dimensioned to the crusher. Most cone crushers have a feed opening size of 5-14", so material that's larger than the maximum size allowable will need a first stage of crushing before they can be fed into a cone crusher. Final Product Isn't Uniform

Primary gyratory crushers are designated by two numbers. These are the size of the feed opening (in inches) and the diameter of the mantle at its base (in inches). A 60″~x~89″ crusher would have an opening dimension of 60 inches (152 cm) and a diameter across the base of the mantle of 89 inches (226 cm).

The capacity is similar to that of a jaw crusher with the same gape, and breadth 'B' equal to the perimeter of the gyratory crusher. Since all the coarse crushers have greater capacities than the devices for the finer ranges of size reduction, a gyratory crusher of sufficient size to crush the required size feed may have an excessive capacity.

5. Distribute the feed evenly. Crusher feed should be evenly distributed around the centre of the crushing chamber. Avoid feed segregation where the coarse new feed is on one side of the feed opening and the finer recirculated feed is on the opposite side of the feed opening. 6.

Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in.
