    9/2/2019· 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.

    11/1/2004· Gyratory crusher2.1. Gyratory crusher importanceGyratory crushers are the usual choice for primary crushing in high tonnage open-pit operations. This is especially true when the ore to be processed is hard and abrasive and the downstream phase requires relatively coarse material such as grinding circuits equipped with SAG mills (Major, 2002).

    Written by AZoMining Apr 23 2014. A gyratory crusher is an ore processing machine that crushes the ore between an eccentrically mounted cone and a crushing throat, that is fixed. In mining, the most important criteria for effective crushing of ores is to choose the type of crusher that suits the rock (ore) material, and to ensure uniform feed.

    Gyratory equipment, used in mechanical screening and sieving is based on a circular motion of the machine. Unlike other methods, gyratory screen operates in a gentler manner and is more suited to handle fragile things, enabling it to produce finer products. This method is applicable for both wet and dry screening. A distinct difference to other techniques is that the gyratory motion applied here depends
