A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. 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. Major components can be divided to ease transport ...

In a gyratory crusher, the combination withl the gyratory crushing head and its operating mechanism, land. a lubricating system for the latter having an enclosure around the same below the head, of spring mounted supporting means for the headandmeans for vertically adjusting said means to raise and lower the head, all enclosed inside the ...

A hydraulic control system for a gyratory crusher has a hydraulically supported main shaft. An inlet line to the cylinder is provided with a pressure relief valve. When the pressure in the cylinder, e.g. because of a disturbance, exceeds the opening pressure of the relief valve, fluid flows from the cylinder through the pressure relief valve to the lubricating circuit of …

The apparatus is a gyratory crusher in which all the wear parts can be removed and replaced from the top of the crusher, thus eliminating the need to remove large, heavy parts from below the crusher. This is accomplished by constructing the crusher so that the eccentric and the piston assembly can be lifted up and out sequentially. The piston …
