specifications sheet
The Supersucker® industrial vacuum loader can be equipped with a pneumatic unloading option to discharge virtually any dry material from the body into a silo, storage hopper, truck or storage containers.
Unloading is accomplished by connecting the air conveying line from the vacuum pump exhaust port to the discharge port of the auger, which is mounted laterally in the tailgate.
Raising the collector body allows the auger to meter material through its discharge port into the pressurized conveying line. Pneumatic unloading cannot occur during the loading operation.
Controls
The velocity of conveying air can be controlled by adjusting the speed of the vacuum pump. Light or fragile materials are conveyed at low speeds and heavier materials at higher speeds. The auger speed can be controlled to increase or decrease the amount of material metered from the body.
Auger rotation is reversible. A pressure gauge is provided to indicate optimum operational conditions. All controls are located at the Supersucker control panel.
Auger
The auger system is an integral part of the tailgate and does not interfere with normal machine functions. The operator can choose to dump recovered material in the conventional manner or discharge material pneumatically through the auger system to a remote location.
The auger can also meter material from the body without pneumatic conveying. The 9” (228.6 mm) diameter auger is double flighted to pull material from both sides toward the center discharge port. The auger shaft is supported by anti-friction bearings and seals.
Auger Drive
The auger is driven by a low-speed, high-torque hydraulic motor using a fully enclosed chain and sprocket arrangement. Hydraulic power is obtained from the Supersucker hydraulic system. Auger speed is controlled by an adjustable hydraulic flow valve.
Relief Valves
When conveying pressure reaches a predetermined level, the unloading system will automatically vent, protecting the complete system.
Vacuum Pump Protection
The vacuum pump is protected by a pressure relief system which vents in the event of a plugged discharge line, plugged filter at the receiving site, or an attempt to convey too large an amount of material.
Discharge Ducting
The air flow initiates from the vacuum pump discharge silencer and continues to the discharge port of the auger. Connections are easily accomplished from ground level with camlok fittings.
Set Up
The discharge ducting and pneumatic conveying line can be easily connected from ground level with 6” (152.4 mm) diameter lines.
