The air conveying chute is suitable for fluidizable powdery materials such as cement and fly ash. It is powered by a high-pressure centrifugal blower (models 9-19:9-26), causing the material in the enclosed conveying chute to flow slowly at the inclined end while maintaining fluidization. The main part of the equipment has no transmission components, uses a new type of coated wheel breathable layer, offers easy sealing operation and management, is lightweight, low in power consumption, has a strong conveying force, and is easy to change the conveying direction!
