Rock Crushing Rule of Thumb - 911 Metallurgist

In a hard rock mine, the product from a jaw crusher will tend to be slabby, while the product from a gyratory crusher may tend to be blocky, the latter being easier to convey through transfer points on a conveyor system. Source: Heinz SchoberScalping is usually recommended before a jaw crusher, whereas gyratory crushers can handle the excavated ore as is. This is because primary gyratories are not as sensitive to fines: they are large, steep and have a relatively short stroke compared with settings that allow fines to flow through more easily.Below the surface: Setting up an underground primary jaw crusherthe crusher and scalp out fi nes.

Jaw Crusher - an overview | ScienceDirect Topics

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. Above crushing rates of 900 t/h, gyratory crushers are almost always used. Gyratory crushers are relatively sensitive to moist feed ...Large-scale crushing operations are generally performed by mechanically operated equipment such as jaw crushers, gyratory crusher and roll crushers. ... These relations are, in turn, helpful to size the opening of the scalping screens that are placed in the ore stream before the crusher. The purpose of scalping screens, also called grizzly ...Jaw Crusher - ScienceDirectJaw crushers are the most common solution in underground applications when the throughput is less than 1,000 tons per hour, depending somewhat on the scalping solutions.Going underground: Jaws or a primary gyratory? - احصل على السعر
