Movacolor says its MBS blenders have a compact and sturdy design
Sturdy design Movacolor has launched its new MBS range of blenders. Having compact and sturdy design, there are no mechanical or moving parts in the hoppers – as well as having modular construction and accurate dosing. “The blenders are of the same high quality as our dosing units and can handle all commonly used materials,” said Klaas Talsma, product manager at Movacolor.
As well as 17 standard configurations, they can also be customised based on the customer’s specific requirements, he added. The standard configurations are divided
into three series: the 3 series, 20 series and the 20 Extrusion series. All Movacolor blenders can dose accurately up to 0.02% and the maximum through- put is set at 1600 kg/h. “Because they are part of our modular concept, they can also easily be upgraded to a Hybrid set-up, where blending and dosing are merged in a single system,” said Klaas.
Custom conveying Pneumatic Vac-U-Max, which manufactures custom pneumatic conveying and support equip- ment, offers its Signature Series pre-engineered 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 diam- eter 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 produc- er, 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 accommodate 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 compressed air reservoir with a solenoid oper- ated 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, bridg- ing, and clinging to restore free flow even with difficult materials.
