The industrial flow-assisting air discs DL15, the powder conveying breaker, the discharge device for the mixing station silo, and the silo air bowl are all pneumatic auxiliary discharge devices used in the powder material conveying and storage system. Their core function is to solve the problems of blockage and poor discharge of powder (such as cement, fly ash, mineral powder, etc.) in silos and pipelines due to agglomeration, caking, and adhesion by using the jetting of compressed air or air turbulence. This ensures the smooth flow of the materials.
