AI Technical Summary

Technical Problem

The existing impact airflow crushers cannot effectively screen out material particles of different sizes during the crushing process, resulting in different sizes of material particles after crushing.

Method used

The screening assembly and fixed assembly are introduced into the crushing device. After pulverizing the material through a powerful airflow, the material is screened using the screening plate. The fine particles are discharged through the screening plate, while the large particles continue to be crushed until they are qualified. At the same time, the material is transported through the dragon rod of the feeding mechanism to prevent poor discharge caused by the airflow strength.

Benefits of technology

Effective screening of materials is achieved to ensure that fine particles are discharged in time and large particles continue to be crushed until they are qualified, improving the crushing efficiency and particle uniformity.
