Reclaim Plastic/Metal with Electrostatic Separators

Newton, KS -- New Plastics-Series and Metal-Series Electrostatic Separators from Bunting Magnetics let users extract, difficult-to-reclaim, small particles from recycled material. Whether separating two types of plastics or metal from a nonmetal mixture, electrostatic separation equipment will effectively remove, clean, separate, or recover material - depending on the users' needs.

Using differences in static electricity, or electricity at rest, to separate materials, the dry process EKS and KWS Series Separators from Bunting can be integrated into an existing recycling operation, or built entirely new.

Plastic from Plastic Separation

Sorting plastic production waste, separating unwanted contaminants in plastics, or producing new product from valuable raw material is easy with user-friendly, low-energy consumption Plastic EKS Series Electrostatic Separators from Bunting Magnetics Co. The separators - which rely on the differences in the static charging behavior of various plastics - can take a mixture of two plastic types and produce a clean plastic separation for each.

For those users who regularly work with plastic-plastic mixtures, cable scrap, plastic production waste, bottle caps, PET beverage bottles, and other plastic mixtures, the EKS Series equipment provides the effective separation they need for recycling and other applications. Because material separation takes place absolutely dry, auxiliary separation liquids and conditioners are not necessary and drying time is eliminated. The reliable unit is capable of segregating two recyclable plastics simultaneously.

Bunting will tailor units to different throughputs and separation tasks; and it can provide integrated material handling equipment and automatic controls for a complete turnkey installation. All Plastic EKS Series Electrostatic Separators from Bunting are equipped with a robust framework and maintenance platform, easy service access, electronics cabinet with programmable controls, security of high-voltage areas, automatic electrode cleaning, and more.

Copper and Electronic Scrap Separation

Recover fine copper threads from cable wastes, extract aluminum flakes from ground PET bottles, or separate precious metal from pulverized electronic scrap with Metal KWS Series Electrostatic Separators from Bunting Magnetics Co. KWS Series electrostatic separators can separate very fine metal particles from recycling materials, such as cable scrap, electronic scrap, or bonding materials.

KWS Series Separators feed raw material into a rotating metal drum that is located inside the separator housing. There the material is exposed to the electromagnetic field created by a high-voltage electrode and becomes electrostatically charged. The conductive metal particles in the mix quickly lose their charge and fall from the rotating drum into metal collection receptacles. The nonconductive material loses its charge more slowly and temporarily sticks to the drum - achieving the desired separation as it falls into a different bin.

The dry separation process again eliminates chemicals, water, emissions, and drying time. High separating efficiency - particularly against the smallest metal particles - ensures product purity. KWS Series Electrostatic Separators from Bunting are fully automatic, easy to operate, and result in a problem-free transition when changing materials. Each unit comes equipped with a basic frame and maintenance platform, electronics cabinet with programmable controls, an integrated de-dusting system, automatic electrode cleaning, security of high-voltage areas, and more.

Bunting has the engineering capabilities and expertise to guide users through the selection and installation of these highly productive systems. Separators are outfitted to meet most requirements and can be custom built if necessary. With KWS and EKS Electrostatic Separators from Bunting, customers can reclaim a wide range of valuable materials.

Jon Naylor Heads Up Vortex Valves in Europe

Salina, KS -- The US manufacturer of bulk dry material handling valves, Vortex Valves, has recruited Jon Naylor to head its emergent UK business. As EU Managing Director, Naylor is developing a UK operation, from which to launch the Vortex Valves brand in Europe and the Middle East.

Vortex Valves has realistic aims though, he says: "The company doesn't expect to storm the marketplace. It has a long-term plan that will be implemented patiently. Having said that, I think the process engineering and bulk handling industries really will welcome this unique new breed of valves."

"In Europe, the valves that are commonplace in dry bulk solids handling, in particular, are often well constructed but, we believe, are significantly over-engineered. Vortex Valves have a string of design awards and almost a 30-year history in the supply of specialized valves for the dry bulk solids handling industry to their credit, yet they are far more cost effective by comparison. I am confident that the relatively small number of OEMs and processors over here, who have heard of Vortex, or already have them in service, will grow strongly. It is an exciting prospect for us but we recognize that is going to take time to develop a long term strong presence in the UK, Europe and Middle East." Naylor continues.

Jon Naylor has previous experience and a wide field of contacts that will serve the Vortex's cause well. With International Pipeline Products Ltd, having global responsibilities as Export Sales Manager, he set up a network of agents in the Middle East. Previously he entered the pipeline industry in 1992, rising to Sales Manager for the UK, Europe, Africa and the Former Soviet Union, with Pipeline Engineering Ltd.

About Vortex Valves

Centered in Salina, Kansas, Vortex Valves supplies dry bulk material handling valves to a worldwide customer base of original equipment manufacturers and process engineering specialists. Vortex Valves are known to handle over 500 different materials. Currently the company is moving to a purpose built, state-of-the-art manufacturing facility and office complex and is introducing leading-edge production technology to further enhance its status as technological leader in its field.

Replace Wood Screen Frames with Auto-Tensioning Frames

Cincinnati, OH -- Replacing wood screen frames with all-metal Automatic Tensioning Screen Frames from Rotex, Inc. improves efficiency, speed, repeatability and cleanliness.

Automatic Tensioning frames feature a patented design for attaching screen clothing to unitized frames with unique Quick-Snap spring tension clips. The clips permit quick removal and replacement of screen clothing and ensure constant, uniform tension across the entire screen surface for superior screening, reduced screen blinding and longer screen life.

With a one-piece design, the Automatic Tensioning screen frames are easy to assemble, clean and maintain, greatly simplifying maintenance, reducing downtime and eliminating the need for spare screen frames.

The screen frames and top covers are constructed of heavy duty 14 ga. mild steel, 304 stainless steel or .125" aluminum. The bottom pans are made of mild steel or 304 stainless steel. Special alloys also can be incorporated into the design and Rotex application engineers are available for advice about the best material to use for specific applications.

Automatic Tensioning frames feature a totally enclosed design with a continuous, one-piece seal and a grooved lip that holds the seal tightly against the frame. The wider, more compliant seal provides a tight seal between the surfaces and won't pull away from the frame during regular maintenance, providing improved sealing and longer seal life.

With the newly designed frame, a simple, one-time adjustment of the patented roller and bumper system ensures proper location of the screen frame - even after repeated screen frame changes. No sieve jacks or additional adjustments are required, and no tools are needed to remove or re-install the screen frame.

Mr. Grim is looking for a removable bin aerator:

I currently drain bins of powder into a blender using gravity and vibration. I would like to reduce the amount of time this takes.

Aeration seems like a better solution than vibration, however, I have a very large number of bins on plant and would like to find a method that does not require all of the bins to be modified.

Is there a product that could be inserted into the opening in the top of the bin for aeration and removed once the bin has been drained? The bin opening is 10" in diameter.  (to post reply, click here)
