Steel recycling system

September 12, 2011

Eriez® and American Pulverizer Co. (APCO) have introduced a system that offers users the ability to provide shred quality steel.

The system is designed around an APCO 60- by 85-in. shredder with integration of several Eriez technologies—the CleanStream™ process, the 90-in. ProSort II airless metal recovery system, the 60-in. FinesSort® Jr. metal recovery system, a rare-earth eddy-current separator, and two pulley magnets—as well as conveyors from Hustler Conveyor Co., a wholly owned subsidiary of APCO.

The new CleanStream process combines the Eriez P-Rex® drum and new Shred1™ separator. According to the company, the drum improves ferrous recovery by 1 to 2 percent, while the new separator produces a low-copper shred. The process separates clean ferrous from other materials, reducing the number of hand sorters required on the processing line.

Suitable for scrap processors, the new airless metal recovery system doubles the number of metal sensors found on the original ProSort machine and positions them on 1-in. centers. These high-resolution sensors are aligned with a new inverted paddle mechanism to help to improve recovery of valuable metals, including automotive wiring harnesses.

The compact design of the FinesSort Jr. metal recovery system allows for recovery of 1-in. and smaller fines. It receives discarded fines material that has passed through an initial screening process and creates two material streams: a clean, nonferrous metals stream and a waste stream.

The eddy-current separators are suitable for material recovery facilities wishing to automate removal of nonferrous metals from trash, municipal solid waste, sand, glass, dirt, construction and demolition debris, electronic scrap, and shredded automobiles. The separators are available in feed widths of 24, 36, 48, 60, and 84 in. and in either eccentric or concentric rotor designs.

The self-cleaning magnetic pulleys are available in 80 combinations of diameters from 8 to 36 in. and belt widths from 8 to 60 in.
