Eriez’s premium recovery option with dynamic pulley separator

Shred1

Eriez is expanding its line of recycling equipment with the introduction of a dynamic pulley separator, which is designed to liberate entrapped steel and magnetic fines from recycled materials.

This equipment improves downstream separation and the grade of non-ferrous metals.

The separator is suited for recovering ferrous fines from ASR and Waste-To-Energy bottom ash.

Positioned upstream from an eddy current separator, the high-strength unit uses a Rare Earth permanent magnet pulley rotating at an off-set speed from the belt, creating an agitating magnetic field. This improves ferrous recovery or removal and allows non-ferrous material to continue to downstream equipment.

For ASR applications, the separator can be used with weaker magnetic drums to recover ferrous nuggets from the ASR stream. Discarded fines material that has passed through the initial screening process goes to the unit for removal of ferrous materials. The non-ferrous fraction can then be further processed on an eddy current separator.

“The agitating action generated the dynamic pulley separator allows for fine ferrous to be recovered while freeing up valuable non-ferrous metals to be recovered downstream,” said Jonathan Schulberg, Business Development Manager for Heavy Industry, Australia and New Zealand. “The Eriez DPS helps to debulk and reduce material burden upstream of eddy current separators and other downstream non-ferrous separation equipment providing for improved Zorba grade and recovery.”

The unit 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.

Shred1 ballistic separator

After more than a decade on the market, the Eriez Shred 1 ballistic separator is still delivering premium, low-copper shred. It  enables scrap processors to secure higher pricing per tonne, resulting in a swift return on investment (ROI).
With global steel demand surging, scrap processors face increasing pressure to supply high-grade ferrous products to steel mills. This ballistic separator meets this challenge by producing premium, low-copper shred from automobiles and other mixed consumer waste containing complex steel components.

It efficiently separates iron-rich ferrous materials from mixed metals and waste streams post-drum magnet flow, producing two distinct fractions – No. 1 Shred, a premium, low-copper (0.16-0.2 per cent Cu) product, and No. 2 Shred, a traditional ferrous product.

Positioned strategically after primary scrap drums and before the picking station, the Shred1 employs a unique magnetic element for maximum ferrous recovery. Schulberg points out that many customers opt to install the Eriez PokerSort to complement the Shred1 by removing long, troublesome components, commonly known as pokers, from the process.

Over the years, Eriez has tested the Shred1 ballistic separator, processing more than 1,000 tonnes of shred using an X-ray analyser. Results consistently show an average copper content below 0.2 per cent, lower than that of the control group from multiple shredder yards.

Schulberg said that scrap processors worldwide are achieving impressive returns with the Shred1.

“By recovering low-copper shred that commands top prices per tonne and reducing the need for hand-picking, the Shred1 is proving its value in the field and earning customers’ loyalty,” he said.
