A gyratory crusher is similar in basic concept to a jaw crusher, consisting of a concave surface and a conical head; both surfaces are typically lined with manganese steel surfaces.
A Gyratory Cone Crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory cone crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory cone crushers can be used for primary or secondary crushing.
