As the electronics recycling movement continues to grow, the selection of products available to support that growth will likely expand as well. There is certainly money to be made as an increasing number of large U.S. cities design and implement that segment of their recycling services to accommodate directives such as the New York State Electronic Recycling and Reuse Act. In 2015, this particular Act will make it illegal for New Yorkers to dispose of electronics as garbage.
The high intensity separation conveyors manufactured by Bunting Magnetics Co. are for e-scrap and automotive recycling. Don Suderman, product manager, said the conveyors are designed for extreme, high gauss fields of magnetic separation and removal of light, magnetic tramp metal fines. The high intensity fields also separate work hardened, 300 series stainless steel from the product stream commonly seen in e-scrap, medical waste and automotive recycling. Conveyor frames are 300 series, stainless steel construction and have tough, thin, urethane endless belts which help to maximize magnetic fields. Separation pulleys are extremely high gauss and 4” in diameter. “These products are available in 8” to 48” widths and length varies by application. The processing capability is 500 to 3,000 lbs. per hour,” said Suderman.
He noted that the Bunting Magnetic eddy current separation conveyors can also be used for e-scrap, plastics and automotive recycling and MRFs. The product utilizes high intensity eddy current fields to optimize separation for a wide range of nonferrous-conductive materials. The conveyors are maintenance-friendly with a drop-down side panel for quick and easy belt replacement. The endless belt is made of high quality urethane with a 1.5” flex wall and sweeper cleats to kick off ferrous contamination. The secondary brush seal outside flex wall prevents material from getting inside the conveyor frame and high speed rotors aid in plastic flake separation. Variable speed controls for both rotor and belt optimize throw, splitter position and separation. The product is available in 2’ to 5’ widths and 8’ length. Processing capability is 1,000 to 12,000 lbs. per hour.
Bunting Magnetics has developed and manufactured precision magnetic products for over 50 years, worldwide and industries served include: recycling, electronics, automobile, plastics, food and printing. Suderman concluded, “We offer a broad range of magnetic materials and components, magnetic separation systems, material handling equipment, magnetic printing cylinders, metal detection equipment, bonded magnetics and assemblies. Our facilities are located in three U.S. locations and Berkhamsted, England.”
According to Dick Reeves, industry sales manager, General Kinematics pioneered the application of vibratory equipment in the recycling industry through several state-of-the-art technologies including the patented, non-binding Finger-Screen™. This design concept for resource recycling has proven to be highly successful in a wide range of applications, including electronics recycling. “The Finger-Screen delivers highly efficient separation and classification performance with a simple, jam-proof movement, custom-engineered to meet your specific classification requirements. The unit’s vibrating motion spreads material evenly across the deck for maximum separating efficiency. Multiple size separating decks enhance classification while staggered finger positions help to prevent material bypass. Separation performance is enhanced as material freely cascades through the unit – with less ‘trapping.’ The result of this is fast, smooth, continuous material flow throughout the entire separation and classification process,” Reeves stated.
He said that conventional wire mesh screening surfaces are prone to hang-ups. Cascading material flow helps separate entrapped items and the Finger-Screen’s unique “cam-out” surface helps eliminate catching and binding. Tapered fingers gradually classify and free tangled materials reducing manual labor costs. Reeves noted how the recycling industry demands equipment that produces cleaner output, higher capacities, varying commodities, and bullet-proof designs. He added, “With Finger-Screen equipment, vibratory motion evenly spreads material for maximum classification efficiency and staggered fingers prevent material bypass while an open, below-deck design permits ‘free fall’ of material to the lower collecting deck.”
Green Machine® Sales (GMS) installed the firm’s first e-waste recycling system in 2003 and president, John Green, is very proud of the company’s products. “Our new, whole computer dismantler system can process up to 10 tons per hour of all types of e-waste – glass monitors, computer towers, whole photo copiers, big screen TVs, keyboards and more. Our systems use strictly American built components and units typically include a 72” wide steel, belt in-feed conveyor, with a provided cart tipper to handle Gaylord boxes. The conveyor can also be fed directly, through use of the customer’s front end loader.” Green said. The dismantling system also has a slow-speed, auto-reverse, tapered-auger design that helps to maintain larger particle sizes while liberating components from their wiring harnesses and steel framing. Sizing screens develop sized streams of like material enabling inspection and further manual dismantling and sorting.
The company’s Green Eye® Optical Sorting Systems are capable of identifying most e-waste streams and can positively sort utilizing high pressure air. Throughput rates for materials including leaded and unleaded glass, different grades of computer boards, plastics and metals are as high as 6 tons per hour. “Our revolutionary detection system is capable of identifying all types of computer boards, leaded from unleaded glass, all colors of ABS plastics and much more. Our test facility in Hampstead, New Hampshire accepts customer samples for testing prior to order placement. Multiple selections of material can be processed with the Green Eye and customers can train directly with GMS or learn via minimal online assistance from GMS Tech Support,” stated Green.
He added that GMS magnetic separators, Green Screens®, vertical impact mills and all types of conveyor products are manufactured with turnkey UL-Listed electrical panels and air filtration systems, designed to keep the user work space safe.
