||Size Reduction Equipment
Last month’s cover article in American Recycler detailed aspects of the ever-increasing trend of electronics recycling. One part of that trend involves the use of machines that convert electronics from their original form, into the material configuration that makes it possible to recycle those electronics.
Cumberland Engineering is a global supplier of granulators, shredders, size reduction systems and recycling systems. “We’ve been a supplier of these products for over 72 years and we work hard to remain at the forefront of technology development and supply, for all market sectors. Annually, we supply 500 to 700 units to markets including e-waste, injection molding, extrusion, thermoforming, recycling and rotational molding. Within these market categories, applications include plastics, paper, metals, wire and cable,” said John Farney, national sales manager.
Cumberland units are used to safely, economically and effectively reclaim valuable resin commodities. This is an evironmentally responsible practice, as well as a large contribution to the bottom line of any manufacturing operation. The units range in capacity from 50 lbs. per hour, to over 15,000 lbs. per hour.
Farney noted that the safe usage, proper maintenance and responsible operation of the units are important, of course. “It is not as simple as ‘the part fit into the unit’ – there are specific methods involved in safe operation, proper processing of materials and the form and volume of the final material stream,” he stated. The marketplace demand for these units is robust, as resin prices remain high while automotive, durable goods, packaging, medical devices and other markets have shown significant growth in this year and also hold promise for 2013, according to Farney.
He concluded, “Having designed more models in the last 10 years than any other supplier, our designs are recognized for superiority, strength, durability and quality. Our position in this industry allows us to set the bar for other suppliers, and this creates the standard the industry expects for equipment performance. We are the highest-rated provider of these products, and our service and skilled sales network are second to none.”
Mike Hinsey, vice president of international sales, said that Granutech has been meeting the demands of scrap processors since the firm was founded 40 years ago. “Our most popular shredder for e-scrap processing in the last 20 years has been our Saturn Twin Shaft Shredder. Our Grizzly grinder is a superb, final sizing machine for reducing low-iron content e-scrap into an evenly-sized fraction for effective separation with eddy current systems or more sophisticated optical and induction sorters. The machine is designed for difficult applications and provides ease of maintenance, backed with unequaled service after the sale,” Hinsey said.
He said that e-scrap is the fastest-growing recycling market today with substantial growth still possible. “We’ve placed machinery around the world in some of the most difficult processing applications imaginable. The largest e-scrap system we supplied had to process 15 tons of material per hour and the location was near Copenhagen, Denmark. Our location in that same area is helpful to us in moving staff or parts to virtually any location in the world, within 48 hours, if needed,” Hinsey explained.
He also noted that Granutech offers the expertise to design a complete system, without the limitations sometimes connected with component suppliers. “We’re able to guide clients in choosing the shredder – twin or quad shaft – that is most appropriate for a given setting. Some shredder manufacturers aren’t able to offer that level of expertise. Systems can be as simple as our twin shaft shredder or as complex as three different styles of machines in a series, with a variety of separation processes,” stated Hinsey.
He said there has been much debate about the proposed export ban on e-scrap, “which is so broad that it would inhibit not only e-scrap processors but traditional scrap processors from moving some globally-traded commodities.”
Hinsley added, “Fortunately, this is being confronted on a number of levels as simply bad legislation and with continued diligence, the ban will be rejected. Trying to create jobs by closing markets is short-sighted at best and perhaps illegal at worst. From our perspective, the biggest challenge is the lack of standardization among state regulations. There is rumbling of federal legislation, but that seems unlikely to materialize as states would expect funding to follow any federal mandate. Europe is more advanced than the U.S. in this area. EU manufacturers must comply with the WEEE [Waste Electronic and Electrical Equipment] directive and failure to comply leads to prosecution. That Directive is quite broad and covers most household appliances except refrigerators. U.S. practices may resemble that directive, at some point.”
For engineered volume reduction solutions for a myriad of applications, Komar offers quad shredders, dual shaft shear shredders, single rotor shredders, auger compactors, feeders and more. “Our industrial-strength products can efficiently grind and process e-scrap as well as municipal solid waste, pallets, cardboard, metal, medical waste, hazardous waste and more. They are in use around the world as companies seek solutions in today’s recycling and waste industries,” said Mark Koenig, president of Komar Industries.
He added, “Security and fast return on investment are hot topics in the world of e-recycling. Our Piranha Single shaft shredder, for example, provides fine grind for circuit boards, wire and cable – in sizes of .5” to 4” for item type separation. The shredding action of the Tiger Electro-Shear employs high-torque, low speed counter-rotating, cutting blades in a variety of tooth patterns and sizes.
It operates at slow speed with minimum noise, dust and energy requirements with electrical automatic anti-jamming action. For an even smaller size piece output, the Tiger 4 Quad Shear is effective for primary and secondary shredding. With a unique, 4-shaft design, it delivers uniform piece size output. Material is kept in the cutting area for high-volume reduction, internally recycling particles over various pitched screens to produce finished sizing from .25” to 4”.
Koenig noted that skilled Komar technicians provide on-site start-up and training so that clients are able to get started right away. Shredding and compacting systems can be equipped with auxiliary devices such as camera monitoring systems, in-feed and out-feed conveyors and other equipment that help the end user monitor the material processing chamber. With added controllers, photo-eye sensors, and light curtains, equipment is designed to provide users with maximum safety and control within a complete turnkey solution. Komar has been in business for over 30 years, with over 140 domestic and foreign patents in waste and recycling processing technology.
