The cone crusher role in asphalt crushing

  Mining crusher is mainly used in the mining process large ore crushing process as gravel or broken stone, generally refers to the original ore after blasting the mountains, Sand washing machineprocessed into finished products to meet the demand granularity.With the development of mining crusher, to a certain extent to improve the overall process of mining crusher in large mining processing as core equipment.Gravel in accordance with the ore feed size and the material grain size crusher for ore primary crushing, secondary crushing and crushing the field.Crusher the crusher applications improve on the basis of product performance has also been improved to meet the demand on the greater. Extrusion and bending of the two jaws of materials in the 1980s, the crusher, the processing of coarse broken or in pieces of various hardness materials;Sand washer moving jaw if work only for simple swing arc , said the industry simple swing jaw crusher;, if working for the swing arc, but also up and down movement, said the complex swing jaw crusher.To the early 1970s, gyratory crusher,brick making machine crushing hammer in the cone cavity in the housing cycle exercise, squeeze the material, splitting and bending, coarse crushing various hardness ore or rock crushing machinery.Broken cone spindle upper end of the support beams the middle of the bush, and its lower end is placed on the sleeve eccentric hole.Sleeve rotation, Sand washing machine manufacturersbroken cone around the machine centerline as eccentric cycle exercise its crushing action is continuous, so the efficiency is higher than jaw crusher. , Crushing operations nesting uniformity of the particle size is generally higher than the high crushing operations requirements, therefore, the lower part of the crushing chamber shall be provided with a parallel zone, the same time, we must speed up the crushing cone cycle speed to the material in the parallel region by extruding more than once.
