Crusher

Abstract

This application provides a pulverizer and belongs to the technical field of pulverizing equipment. [Solution] The pulverizer includes a support frame, a stator, and a rotor. The stator is connected to the support frame and has a stator grinding surface. The rotor is also connected to the support frame and has a rotor grinding surface that is rotatable. The stator grinding surface and the rotor grinding surface face each other, a grinding cavity is formed between the stator grinding surface and the rotor grinding surface, and the distance between the stator grinding surface and the rotor grinding surface is adjustable. Because the distance between the stator grinding surface and the rotor grinding surface is adjustable, the distance between the stator grinding surface and the rotor grinding surface can be adjusted according to the required particle size of the material, thereby allowing the pulverizer to grind materials to different particle sizes, thus providing broader applicability.
