Eriez offers expanded testing services

Eriez, Erie, Pennsylvania, a company that designs, develops, manufactures and markets magnetic separation, metal detection and materials feeding, screening, conveying and controlling equipment, is offering expanded lab-scale testing services for recycling companies. Eriez’s testing is performed at the company's Central Test Lab in Erie.

According to Eriez, the majority of test work for recycling applications focuses on ferrous and nonferrous magnetic separation.

Eriez says test procedures are customized to each customer and based on specific challenges. Some of the most common recycling tests conducted center on recovery of copper wire/fine zorba from auto shredder residue (ASR) fines, separating minus 2-inch zorba into twitch and zebra, recovery of fine aluminum and copper from wire chop, stainless steel recovery from fine zurik packages, ECS negatives and ASR fines and aluminum separation from PET (polyethylene terephthalate) flake.

“After processing customers' materials on the recycling equipment, we can determine recovery rates and make judgments on material grade,” says Chris Ramsdell, Eriez recycling equipment product manager. “With these recovery and grade figures, we can often help the customer determine equipment payback periods to support their investment.”

Lab testing also allows Eriez to map out potential process flows, mix and match different pieces of equipment and determine recovery rates based on where a particular piece of equipment will be located in a process flow. “Our experience has shown we can provide reliable and accurate predictions for plant-scale results based on our lab-scale tests,” says Ramsdell.
