AI Technical Summary
Flour tends to accumulate on the outer circumference of the screen during the vibrating screening process, causing blockages. Large lumps of material can also clog the discharge port, making it difficult to discharge the material.
The vibrating ring drives the slider and vibrating teeth to vibrate up and down, striking the screen cloth, accelerating the material's fall, and allowing the material to pass through the mesh of the vibrating screen, preventing the screen cloth from clogging.
It effectively prevents screen cloth clogging, increases feeding speed, crushes large pieces of material, and maintains the fluffiness of the material.
