[0002] Crusher, also known as stone crusher, is a crushing machine used in the processing of metal and non-metallic ores. It can crush the mined raw ore into small particles by squeezing and bending. Among them, cone crusher is suitable for medium or fine crushing. The uniformity of the discharge particle size of medium and fine crushing is generally higher than that of coarse crushing. Therefore, a parallel zone must be set at the bottom of the crushing chamber. At the same time, the rotation speed of the crushing cone must be increased so that the material is squeezed more than once in the parallel zone.
