Information security is as important as ever and that is just as true regarding the recycling of electronic waste.
BCA Industries builds specifically designed electronic shredding and recycling systems. John Neuens, sales and marketing director, commented, “The electronics recycling market is perhaps the segment of the industry where I see the most innovation driven by the variety of materials in assemblies. Some very real problems from privacy concerns, toxicity of materials, explosive battery issues to rare earth reclamation challenges must be resolved. We have recently been working on a Department of Defense project that requires all electronics discarded past life cycle to be reduced to 2mm. This requirement was difficult to provide as the work also involved harder metal materials which were mixed with a large variety of recyclables. The situation caused us to think anew about whether traditional methods of reduction could even be used while also meeting the production needs involved.”
He added, “The dynamics of that situation were similar to those of the lithium ion and nickel cadmium battery recycling systems we have developed. New methods and technologies were required so that we could bring a new value to the recycled material results. The reduction specification created by information privacy required us to develop a multi-staged system that took into account the sizing, heat dissipation, maintenance, air quality, innovative screening and recirculation designs—as well as some new separation methods that met the customer’s expectation. The innovation of all our electronic devices creates innovation in the whole of the recycling industry.”
With shredders ranging from 60 to 2000 h.p., Granutech’s Saturn shredders are an ideal fit for e-scrap producers that are in need of a shredder for hard to shred material or with a high volume of material to process. The firm’s most popular shredders for e-scrap are Saturn dual and quad shaft shredders such as the 52-32HT and Q44.
“Quad shaft shredders offer more flexibility with final product size because of the integral sizing screen, which retains oversize material in the shredder until it is small enough to fit through the screen. Our customers in the e-scrap business demand reliability and flexibility from their machinery and suppliers. A range of offerings and features include interchangeable sizing screens on the quad shaft shredders. Saturn shredders continue to meet our customer’s needs as they grow their business and their needs change,” said Michael Graveman, regional sales manager for Granutech-Saturn Systems.
Graveman noted that the industry is trending toward further recovery through use of downstream separation equipment such as magnets and eddy current machines. Though Granutech does not manufacture these, Graveman warned against overlooking the importance of shredding because the separation equipment is not able to effectively separate material until it is liberated by the shredding process.
Serving the needs of the recycling industry for more than 50 years, Granutech Saturn is a leader in the manufacture of size reduction equipment. Manufactured at the firm’s factory in Texas, the Saturn line of single, dual, and quad shaft shredders are valued for extreme durability and toughness, with the majority of machines produced still in operation.
“Whether you’re looking for separation and material recovery, or complete data destruction, the Bengal Machine family of brands is the only size reduction company uniquely situated to offer customers a complete, turnkey system capable of reducing large bulky e-waste to a fine particle size, under 2mm. We can help you design the right system to meet your needs from primary shredding to fine grinding, and everything in between. Our systems are perfect for both ferrous and nonferrous metals recovery material separation and complete data destruction. We offer unique designs ideal for reducing large, bulky materials to a fine consistency, and grinding free flowing material to an ultra-fine finished particle size,” explained Bill Castine, sales director.
Castine suggested that for primary shredding, CM industrial shredders are perfect for high volume e-waste or electronics scrap shredding and processing, for materials destined for reuse, resale, salvage, recycling or disposal. CM Shredders feature patented knife technology which reduces cost and machine downtime. They are low noise, low dust, low heat, and highly precise.
The Schutte Hammermill brand offers a line of secondary fine-grinders for electronics processing. The dual stage E-Destroyer Hammer Mill offers super-fine electronic scrap grinding, under 2mm, at very high production rates. The energy resulting from the dual revolving rotors produces a suspension zone that provides additional size reduction. As a result, a finer grind is achieved in one pass through the mill.
The E-Cycler hammer mill completely scours electronic media of data while simultaneously liberating the majority of components for easy separation and recycling. With the ability to process hard drives at a rate of one per second, the E-Cycler can also process cellular phones, printed circuit boards, semiconductors and more – all without any system reconfiguration. All equipment is available in a range of sizes, and is custom configured to meet the demands of specific applications.
