Gyratory Crusher - an overview ScienceDirect Topics

A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening. Hammer crushers are used either as a one-step primary crusher or as a secondary crusher for products from a primary ...

2. GYRATORY CRUSHERS

The gyratory crusher, whether used as a primary or secondary. is essentially a gravity-type machine. Material flows vertically from top to bottom. It receives a large coarse feed, usually run-of-mine, and its product normally requires additional crushing before produc- ing the final product. The gyratory crusher is a pressure crushing device as is the jaw crusher. The crushing action itself is ...

Gyratory and Cone Crusher - ScienceDirect

2016-01-01  Gyratory crushers can accept 8–10% moisture in operation, but the fine content should be preferably less than 10%. The crushing action in gyratory crushers is regarded as rings or ‘helics’ (spirals) of feed down through the crusher of which a single section may be regarded as similar to the jaw crusher. Therefore, computations leading to the performance of gyratory crushers may be ...

Symons Cone Crusher - 911Metallurgist

Another point for consideration is that the 10 Ft., cone crusher is a secondary crusher and normally would be fed with the product of a gyratory crusher. Since the 10 Ft. can accept a larger feed than a 7 Ft. crusher, it is possible to increase the open side setting of a gyratory crusher, thereby, allowing a greater volume of feed to pass through the crusher. Because of this, it is conceivable ...

gyratory movement ECCENTRIC JAW CRUSHER

Since the present crusher utilizes the gyratory movement of the eccentric, it can be compared with known gyratory and eccentric roll crushers of Rapidex Inc. and Joy Manufacturing Co. The working cycle of the present crusher is almost doubled in comparison with conventional jaw crushers. Therefore, it works more uniformly with the less horsepower, dynamic load and mass of the crusher.

Crushers - All crusher types for your reduction needs ...

Gyratory crushers are frequently used in the primary crushing stage and a little less often in in the secondary stage. Gyratory crushers have an oscillating shaft. The material is reduced in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.
