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

Cone crushers are commonly used for secondary, tertiary and quaternary crushing duties. Two variations are available - standard and short head The chief difference between cone and gyratory or jaw crushers is the nearly parallel arrangement of the mantle and the cone at the discharge end in the cone crusher.

Dec 17, 2021 Crusher Stampede WARLORDs get three new traits to choose from, while PSYKERs can pick from the three powers in the Mass Convergence discipline (which is a hell of a name). Trait-wise, the most exciting is probably Raging Influence , which is an aura of extra hits on 6s in melee for MONSTERS, which will usually include the Warlord themselves

Cone crushers . 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

Double Roll Crushers. Double Roll Crushers typically follow a primary or secondary crusher and are used for secondary and tertiary reduction of various minerals, such as ROM coal, clean coal, limestone, gypsum, trona, shale, bauxite, oil shale, coke, salt, lime, glass, kaolin, brick, shale and wet, sticky feeds

Jan 17, 2014 There are five crushers consisting of primary crusher, secondary crusher, tertiary crusher, and two crawler crushers at this crushing facility. The ore coming from the quarry is passed from the grid with a clearance of 150 mm and the material above a grain size of 150 mm are conveyed to jaw crusher with a capacity of 400 tonne/h

crushers to extend plant lifetime and boost production. The modular concept makes the C Series jaw crushers easy to install.
