Continuous Vacuum Feeder, CVF Series
Enclosed vacuum conveyor for continuous transferring of powders and granules to downstream powder processing equipment
The CVF continuous vacuum feeding system consists of a vacuum valve chamber, isolation chamber, filter unit, reverse air cleaning system, feeding mechanism, and rotary airlock valve. It enables both continuous material feeding and continuous discharge, significantly enhancing conveying efficiency. The conveying system cam be integrated with other powder processing equipment such as milling, mixing, or screening machines to form a complete continuous conveying line that replaces positive pressure conveying and eliminates dust leakage or explosion risks.
