AI Technical Summary
When screening slag powder, the existing air classifiers are prone to clogging of the screen holes, resulting in low classification efficiency and poor classification accuracy, leading to poor screening effect.
The screen uses an inclined and concentric inner and outer screen cylinder, combined with a dispersing mechanism and a vibrating mechanism. The dispersing mechanism, through the dispersing rod, and the vibrating mechanism, through the cooperation of wedges and springs, prevents screen hole clogging and improves screening efficiency. The vibrating mechanism, through the sliding of wedges and springs, drives the screen cylinder to vibrate, preventing clogging and ensuring screening effect.
It effectively prevents screen hole clogging, improves the grading accuracy and screening efficiency of slag powder, and ensures the long-term normal operation of the screening device.
