Vacuum Conveyor

Product description

The continuous vacuum conveying system uses negative pressure enclosed transportation, with a star-type discharge valve enabling uninterrupted suction and discharge. Made of 304/316 stainless steel, it features pulse back-blow dust cleaning and can be connected to mixers, sifters, and packaging machines. It enables 24-hour automated powder conveying with no dust or leakage, suitable for food, chemical, and lithium battery powder and granular materials.

Working principle

The vacuum pump generates negative pressure inside the hopper. Powder is sucked into the chamber through the suction pipe by air pressure difference. Filters separate powder from air. The rotary star discharger continuously discharges materials. Meanwhile, pulse air blows the filters to prevent blockage. Suction, filtering, dust‑cleaning and discharging run simultaneously to realize continuous closed‑loop powder conveying.

Product features

1. Continuous non‑stop feeding, 24‑hour stable operation with star discharger.
2. Fully closed negative‑pressure conveying, zero dust leakage, low material loss.
3. Automatic pulse filter cleaning to avoid filter blockage.
4. 304 / 316 stainless steel structure, easy disassembly and cleaning.
5. Seamlessly connect with mixer, sieve, packing machine, reduce manual labor.
6. Explosion‑proof optional, gentle conveying keeps material integrity for powder & granules.
