Eriez® DensitySort™ Air Table Helps Users Recover 70 Percent of Red Metals from Nonferrous Fines
Erie, PA — The economical DensitySort™Air Table from Eriez®quickly and efficiently sorts nonferrous “fines” product into two fractions: Twitch (light fraction) and Zebra (heavy fraction). This separation improves their value.
“Nonferrous fines, or Zorba, from automobile shredders typically contain eight to 12 percent heavy metals,” explains Mike Shattuck, Product Manager—Recycling Equipment. “By further separating these materials, processors can increase their fines value by nearly 20 percent!”
Eriez’ cutting-edge DensitySort Air Table uses air, vibration and slope to separate the fines fraction. Unlike other density separators, Eriez DensitySort does not require a media base such as sand, water or filtration to achieve a separation.
As product is fed at the high point of the table’s slope, its own specific mass directs the product to the low or high side of the table, providing an upgraded high grade aluminum product, (twitch), as well as a heavy product containing nearly 80 percent heavy metals by weight.
Once a fluidized bed of material is maintained, the heavy products sink to the bottom of the burden and travels up the table to a discharge point. The light fraction remains on top of the burden and travels to the low side table discharge. Any product that does not get separated on the first pass re-circulates until it reaches the appropriate discharge.
The DensitySort is designed to process ¼” x 1” and also 1” x 2” fractions without a change to the set-up of the machine.
