sand, water or filtration. As product is fed at the high point of the table’s slope, its specific gravity directs the product to either the low or high side of the table, creating the upgraded aluminum scrap product (twitch) as well as a heavy product containing nearly 80 percent heavy metals by weight. As a fluidized bed of material is maintained, the heavy products sink to the bottom and travel to a discharge point. The light fraction (aluminum) remains on top of the burden and travels to a different low-side table discharge point. Any product that does not get separated on the first pass re-circulates until it reaches the appropriate discharge, says Eriez. The end result for automobile shredder operators is the production of an aluminum twitch product that meets the ISRI specification and/or the specifications desired by the end consumer or broker seeking to buy the twitch grade.

ASR Mill
A WINNING HAND At the 2012 ISRI Convention Eriez will be introducing and displaying its PokerSortTM machine, one of the most recent developments of its 3D research and thinking. The innovative new PokerSort helps alleviate issues caused by long rod-like pieces typically over 24 inches in length, commonly referred to as pokers, which can damage downstream post-shredder sorting equipment. “Pokers, as their name implies, often poke through conveyor belts, causing jams and bridging conditions that can shut down an entire facility,” says Brian Vrablic, sales engineer. “Even a few minutes of downtime can cost thousands of dollars in saleable product.” Utilizing a special magnetic drum positioned at the end of the shredder discharge belt, the PokerSort separates pokers as they catapult off the end of the belt with a different trajectory than the
rest of the shredded material or “frag.” A PokerSort test unit was installed at Erie, Pa.-based Liberty Iron & Metal LLC in late 2011 and on-site testing has proven the PokerSort’s remarkable performance, with 90 percent of pokers eliminated. “Pokers in the frag stream is an age-old and extremely common problem in the recycling industry,” says Mike Shattuck, Heavy Industry Project Manager for Eriez. “We listened to our customers, studied the situation and set out to develop a solution.” “With Eriez’ 70 years in business, one of our main objectives has been to design equipment to help customers solve their toughest challenges,” says Eriez CEO Tim Shuttleworth. “We are committed to ongoing investment in R&D so we can continue to introduce cutting-edge products such as PokerSort that enable our customers to become more efficient and profitable.”

Complete Ferrous and Non-Ferrous Metal Separation Packages
American Pulverizer Co., of St. Louis, Missouri offers a center-feed, high-speed hammermill for processing Auto Shredder Residue (ASR) designed to yield a higher metal recovery percentage. The shredded product that is created reduces material to a more manageable state that can be reprocessed through metal separators to yield higher recovery rates from non-ferrous metals. The mills are designed for high production with minimal maintenance. Design is based on years of experience with ASR and other E-Scrap products. Recovery vol4
