The company says the equipment increases profitability by improving downstream separation and the grade of nonferrous metals.

Recycling equipment manufacturer Eriez, Erie, Pennsylvania, has launched the Dynamic Pulley Separator. The equipment is designed to free steel and weakly magnetic fines from recycled materials.   

The company says the equipment increases profitability by improving downstream separation and the grade of nonferrous metals. The Dynamic Pulley Separator is suited for recovering ferrous fines from ASR and waste-to-energy bottom ash.   

The equipment is positioned upstream from an eddy current separator, and uses a rare earth permanent magnet pulley rotating at an offset speed from the belt, creating an agitating magnetic field. This improves ferrous recovery or removal and allows nonferrous material to continue to downstream equipment.    

For ASR applications, the Dynamic Pulley Separator can be used with weaker magnetic drums to recover ferrous nuggets from the ASR stream. Discarded fines material that pass through the initial screening process goes to the Dynamic Pulley Separator for removal of ferrous. The nonferrous fraction can then be further processed on an eddy current separator.    

“The agitating action generated by the Dynamic Pulley Separator allows for fine ferrous to be recovered while freeing up valuable nonferrous metals to be recovered downstream,” says Chris Ramsdell, Eriez Recycling product manager. “The Eriez DPS helps to debulk and reduce material burden upstream of eddy current separators and other downstream nonferrous separation equipment providing for improved Zorba grade and recovery.”   

The new Dynamic Pulley Separator is also effective for ferrous removal from plastics, rubber and similar materials. These separators provide a high-powered agitating magnetic field to pull metal contaminants out of the product flow, improving purity and protecting downstream equipment from damage.    

The Dynamic Pulley Separator is available in 40-inch and 60-inch widths and can be accommodated for base or suspended mounting ahead of an eddy current separator. For more information on Eriez recycling equipment, click here for more.
