Primary Crusher an overview ScienceDirect Topics

Primary gyratory crushers are used in the primary crushing stage. Compared to the cone type crusher, a gyratory crusher has a crushing chamber designed to accept feed material of a relatively large size in relation to the mantle diameter. The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of

1/1/2016· 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. In some cases, installation of a tertiary crusher is required where the maximum reduction is about 10:1. The secondary crushers are also designed on

Primary crushers play an integral role in the mining process by reducing the size of large run-of-mine ore pieces to acceptable sizes. The main shaft is a large cone-like structure which rotates within a chamber, crushing the large rocks which are being fed. into the system by haul trucks. As the system is operational 24/7, the main shaft incurs

Cone Crusher Manufacture of Crushing & Screening

The Cone crusher is operates via electric motor that drives a horizontal shaft & pinion bevel gear further rotating a crown bevel gear mounted on an vertical eccentric sleeve creating a gyratory motion that affects the centre axle fitted inside the sleeve creating a compression crushing action between the Mantle & concave section. As the mantle moves, it crushes the material against the concave at the points

18/12/2019· The gyratory crusher has capacities starting from 1200 to above 5000 t/h. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Therefore, primary gyratories require quite a massive foundation. The cone crusher is a modified gyratory crusher. The essential difference is that the shorter spindle of the cone crusher is not
