The important ore crusher in mining ore benefication-- Gyratory Crusher

Gyratory Crusher is widely used in metallurgy, construction, chemicals , utilities and other industries, As it has a feature of big crushing ratio, high capacity ,uniform end product size, simple construction, reliable operation, easy maintenance, low operating cost, Gyratory Crusher is the ideal primary equipment for Coarse crushing stone or rocks. Shanghai shanbao is a famous gyratory crusher manufacturer, it has advance technology and excellent service, it you have any require, you can contact it! 

If you want to buy gyratory crusher, you need to know structure about gyratory crusher's. Shanghai Jianshe Luqiao Machinery Co., Ltd can give you a detail analys. 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. The inner cone has a slight circular movement, but does not rotate; the movement is generated by an eccentric arrangement. As with the jaw crusher, material travels downward between the two surfaces being progressively crushed until it is small enough to fall out through the gap between the two surfaces.

With the development of industry, a gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Shanbao gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing. The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by an eccentric on the bottom of the spindle that causes the central vertical spindle to gyrate. The vertical spindle is free to rotate around its own axis. The crusher illustrated is a short-shaft suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. The short-shaft design has superseded the long-shaft design in which the eccentric is mounted below the gear.
