    Graney: “Typically, a primary gyratory will have a similar volumetric capacity, independent of hardness, unless the rock is significantly harder. Most of the time the drop-off in capacity is due to coarser run-of-mine feed. In either case, we can look at increasing the throw, speed or OSS,” he explained.Gyratory Crusher Rock Crushing Machine HPOWER,A gyratory crusher is used as a quartering hammer to extrude and crush materials, making it an ideal piece of equipment for the coarse crushing of ores and rocks in a variety of hardness rates.

    The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment).. This crusher can handle products with a Mohs hardness that is not necessarily less than 5. As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.Crusher Wikipedia,A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
