Powder Handling & Processing Equipment and Systems

Continuous Vacuum Feeder, CVF Series

Enclosed vacuum conveyor for continuous transferring of powders and granules to downstream powder processing equipment

Continuous Vacuum Feeder, CVF Series

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.

The CVF vacuum feeder enables continuous discharge, eliminating the “stop-suction-discharge” cycle fluctuation common in batch systems. It also ensures smoother conveying and a more uniform material flow as well as, avoids level fluctuations, maintaining a stable feed for downstream equipment. It is particularly suitable for continuous production lines or batching systems.

The CVF continuous vacuum feeder supports highly customized configurations. Options include discharge structures compatible with screw metering units, mixers, or reactors; control system integration with client PLCs or automation platforms; and material options such as stainless steel 304 or 316L, as well as explosion-proof grades for specific process environments.
