The Shred1™ Ballistic Separator from Eriez uses ballistics to separate iron-rich ferrous scrap from much of the mixed metals and waste material in the post-drum-magnet flow. The Shred1 delivers three distinct fractions: a premium, low-copper content No. 1 shred; a traditional No. 2 shred; and a heavy/light/waste mix.
When the Shred1 is combined with Eriez’ P-Rex® permanent rare-earth magnetic drum, the system is referred to as the CleanStream™ Process. The CleanStream Process is designed to recover more ferrous and to concentrate 75 percent of the post-drum-magnet flow into a low-copper premium shred. It also eliminates the need for a scavenger magnet, a z-box air system and hand picking the entire flow.
The Shred1 Ballistic Separator can produce the following fractions:
- A high-value, low-copper content ferrous product with a higher value than a No. 2 shred fraction. Fraction one represents 60 to 80 percent of the incoming material flow and contains less than 0.2 percent copper.
- Fraction two is approximately 20 to 30 percent of the incoming material flow and contains mostly mixed metals, copper and aluminum with steel housings or cores. Hand sorting can be accomplished with relatively few pickers because only a fraction of the total shredder discharge must be picked.
- Fraction three consists of heavy steel objects and light material, such as fluff, rubber and some wire. This fraction can be picked with the second fraction or stock piled and reprocessed later. Fraction three contains 5 to 7 percent of the incoming material flow.
