The HDV 6000 vacuum conveying system is a high performance energy saving system. It is well suited for conveying materials that are fragile, abrasive, heavy, light, fine, coarse or difficult-to-handle. This system can convey the materials at a high solids-to-air ratio and low conveying line velocity, with little degradation or system wear. And, the HDV 6000 system requires few moving parts, keeping the cost moderate.

The primary power source of the HDV 6000 system is the vacuum pump that can produce up to 29 inches of mercury. The system can be operated in Full Line Concept mode under certain conditions and many materials can be conveyed with greater control.

An advantage of this system is that it does not require a pickup velocity at the beginning of the system. This keeps typical terminal conveying line velocities from a low of about 300 feet per minute up to about 1,000 feet per minute. For optimum performance, the conveying distance should be limited to 100 feet.

Primary components of the HDV 6000 system include a pickup nozzle at the beginning of the system; a vacuum conveying line with couplings and tubing bends; 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 end of the system. All the air needed to convey the material is added at the beginning of the conveying line.

At the start of the system, or at the pick-up point, material is usually flood fed to the pickup nozzle by controlling the air volume and pressure. The material and air move through the conveying line to the vacuum filter/receiver. As material enters the vacuum filter/receiver, the conveying air is separated from the material and the air passes up through the filter media and then through a secondary filter before entering the vacuum pump.
