AI Technical Summary
Existing water-reducing agent screening devices are prone to material clogging and agglomeration, which affects screening efficiency and cannot effectively handle large pieces of material, resulting in waste of finished product.
A screening device for finished water-reducing agent products was designed, comprising a drum screen mechanism, a cleaning component, and a crushing component. The drum screen mechanism can pre-crush materials, and the cleaning component regularly cleans the screen holes to avoid clogging and improve work efficiency.
It effectively avoids material blockage and clumping, improves screening efficiency, reduces finished product waste, simplifies operation procedures, and improves work efficiency.
