Dec 23, 2015· A gyratory crusher consumes less power when idling and will reduce the size of 2X the rock for the same energy utilized by the jaw crusher. There is less waste or scrap metal coming off a jaw crusher liner (it is reversible) which affords the jaw crusher with a less maintenance.
Sep 02, 2019· GYRATORY CRUSHER. A gyratory crusher uses a mantle that gyrates, or rotates, within a concave bowl. As the mantle makes contact with the bowl during gyration, it creates compressive force, which fractures the rock. The gyratory crusher is mainly used in rock that is abrasive and/or has high compressive strength.
Gyratory Crushers — A gyratory crusher is a jaw crusher with circular jaws that crush the material between it. As indicated in Table 2-5, a gyratory crusher has a much greater capacity than a jaw crusher with an equivalent feed opening. The three basic types of gyratory crushers are pivoted- spindle, fixed-spindle, and cone.

What is the main difference between the mechanism of a cone crusher and gyratory crusher? Primary, secondary and tertiary. What stages are impact crushers used for? Impactor and Hammermill.
Cone crushers resemble gyratory crushers from technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed.
The gyratory crushers crush to reduce the size by a maximum of about one-tenth its size. Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place. Here, the maximum reduction ratio is about 8:1.
