2. GYRATORY CRUSHERS

GYRATORY CRUSHERS The original patent for the gyratory crusher was granted to Phile- tus W. Gates in 1881. This fint crusher was used by the Buffalo Cement Co. At the time these early gyratory crushers were developed all mining and quarrying, either underground or open pit, was done by hand; tonnages generally were small and product specifications simple and liberal. Likewise plants were

Gyratory and Cone Crusher - ScienceDirect

01/01/2016  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 ...

The Gibson Gyratory Crusher works upon the same principles as a hand-held mortar and pestle, just within a much larger scale. The one inch diameter chuncks of material are fed into the machinery and as the heavy shaft turns in circular “gyrations”, the ore is crushed beneath it. There is a sump (catchment area) located between the annular die and the launder crusher outlet that is called ...

TECHNICAL NOTES 5 CRUSHERS - Mineral Tech

Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape.
