The performance of a pulverizer is closely related to its pulverization mechanism and structural characteristics. The crushing mechanism of a general impact crusher mainly relies on the shearing, rubbing, and impact generated between the high-speed rotating rotor and the fixed toothed liner to crush the material into fine particles. In addition to the above functions, this crusher also has advanced ultrasonic impact crushing function, which generates high-speed airflow to take away the heat generated during crushing, avoiding local overheating and suitable for crushing special materials and heat sensitive materials.
