The universal crusher utilizes the high-speed relative motion between the movable toothed disc and the fixed toothed disc to achieve crushing of the crushed material through a combination of tooth impact, friction, and material impact with each other. The structure of this machine is simple, sturdy, runs smoothly, and has good crushing effect. The crushed material can be directly discharged from the grinding chamber of the main machine, and the particle size can be obtained by replacing different aperture mesh screens. In addition, the machine is made of all stainless steel. The inner wall of the casing has been machined to achieve a smooth surface, changing the previous rough and powdery phenomenon of the inner wall of the model, making the production of drugs, food, chemicals, etc. more in line with national standards and meeting GMP requirements.
