A fines recovery system from Steinert lets Sadoff Iron & Metal
gather more metal.

The auto shredder at the Sadoff Iron & Metal fa­cility in Fond du Lac, Wis., produces a wide variety of shredded material, includ­ing small metal particles.

Thanks to a fines recov­ery system from SteinertUS LLC that was installed in mid-2008, the Wisconsin scrap recycling firm is now recovering a greater volume of those small particles, in­cluding both ferrous and nonferrous metals.

“The whole Steinert sys­tem works in conjunction as one,” says Sadoff Nonferrous Operations Manager John Eide. It has been op­erating at the Fond du Lac shredder yard since late May of 2008.

A Steinert Dual Stage/ Dual Metal Pre-Separator working in-line with a Stein­ert 6119 High Frequency Eddy Current Separator (ECS) combine to capture both magnetic (ferrous) fines and then small nonfer­rous metal pieces that used to pass through Sadoff’s previous downstream system.

“The system works in three stages in total, first pulling out pieces of iron that are marketable,” says Eide. “Then the iron fines are picked up.”

"After that," says Eide, “the material is iron-free when it goes to the eddy current.”

The High Frequency ECS has been adept at recover­ing several nonferrous met­als. “We’re capturing a zor­ba fines-type product that is about 90 percent metal.”

For Sadoff Iron & Metal, the end result is the cap­ture of more metal from a stream of material (the less than 1.25-inch fraction) that the company used to send off site for additional pro­cessing.

“We’re very pleased with the results of the Steinert system,” says Eide. “This fines processing system is generating additional value from metal units that might have formerly been lost.”

An aluminum-rich end product is one result of Sadoff’s Steinert system.

As with other Steinert equipment Sadoff Iron & Metal operates, Eide says the new machines are “re­liable and durable. We’ve had great success with other magnetic equipment from Steinert, and their ser­vice is always above and beyond.”

The way the stream of small pieces has been turned into “gold” has im­pressed Eide.

“We’ve re­covered a great deal of metal with these machines in just four months’ time. That type of result is going to pay for this system much more quickly than we antici­pated.”
