Custom conveying Pneumatic Vac-U-Max, which manufactures custom pneumatic conveying and support equip- ment, offers its Signature Series pre-engi- neered plug-and-play vacuum receiver line for conveying powders, fibres, flakes and difficult-to-convey materials. Two models are offered in the line, including a 1500 series model that can vacuum convey up to 1,500 lb/hr (680 kg/hr) and features a 12in diameter receiver with a 6in discharge valve in stainless steel. An offset cone or tube
design are options. The 3500 series offers
conveying rates up to 300 lb/hr (1,600 kg/hr) with a 16in diameter receiver and an 8in diameter discharge valve. The system consists of five parts: the receiver, vacuum producer, conveying wand, tubing and controls. Vac-U-Max has also developed vacuum convey- ing systems that allow automatic refilling of volumetric or gravimetric feeders used in batch and continuous processes “Many times the feeder is purchased without
consideration of how the feeder will get filled and refilled,” the company said. Vacuum receivers integrate easily for volumetric
refill applications and meter material to the feeder by immediately discharging material into the hopper when the feeder reaches a low-level signal. The Vac-U-Max receiver always maintains a charge of material ready for dispensing into the feeder, allowing the refill process to occur in seconds. The process repeats until all the material has been
conveyed or when the operator turns off the control panel.
Its mobile vacuum conveying systems offer ease
of mobility for applications requiring access to hard-to-reach processing areas. The unit has a rolling frame that can lift the receiver to accommo- date varying discharge heights or be lowered to the operator level for maintenance, disassembly, and transport. It can be rolled to – and positioned at – the desired discharge point. The vacuum power source and the control panel are mounted onto the rolling frame and can convey up to 5,000 lb/hr (2,268 kg/hr) of granules or powders and manages the conveying, discharge, and filter cleaning functions of the system. The system incorporates an adjustable suction wand which the operator uses to introduce material into the vacuum system. The company also designed a pulsonic system
that introduces sonic air bursts directly into any compacted mass flow devices to instantly restore material flow without severe shock and vibration – which can damage hoppers. Its Pulsonic Bin Activator is designed with an injector, consisting of a com- pressed air reservoir with a solenoid operated valve, and a programmer for controlling the pattern of multiple air bursts from the injectors. The system comprises a single programmer and one or more injectors to instantly clear bins, hoppers, and other mass flow devices of compacted solids, removing disruptive materials from channels, ducts or recesses. The system breaks up arching, bridging, and clinging to restore free flow even with difficult materials.
