Continuous Dense Phase Vacuum System
The HDV 6000 Vacuum Concept Conveying System is a dense phase, medium velocity, high pressure, continuous vacuum conveying system. It is generally used to convey low to high density, granular or pelletized, and semi abrasive materials. Examples include plastic pellets, granulated sugar, salt, coffee beans, pinto beans, and peanuts.
Typical conveying velocities are 300 to 1000 feet per minute (1.5 m to 5 m/sec) and vacuum conveying pressures of up to 29 inches (737 mm) of Mercury (hg).
The material is fed into the conveying line on a continuous basis by vacuum which is supplied by a high pressure vacuum pump. The system includes a vacuum pickup nozzle, a vacuum conveying line, a vacuum/filter receiver, a secondary filter and a vacuum pump. For continuous conveying applications, a gatelock hopper with an inlet and outlet valve is installed at the discharge of the vacuum receiver.
