Gyratory crusher use crushing cone in cone shell cavity in the turning motion, produce compression, splitting and bending of the material, crushing various ores or rocks large crushing machinery. Main shaft with cone crushers at the upper end of the supporting beam in the Bush in the middle, the lower end is arranged in the sleeve of the eccentric hole in. Shaft rotates, broken broken cone winding machine center line of action for eccentricity cycle movement it is continuous, so the working efficiency is higher than that of jaw crusher. To the early *0's, large crushing machine per hour can handle material ***0 tons, the maximum feed diameter up to ***0 mm.
