Ballistic separator segregates copper-bearing material from ferrous

Eriez offers the Shred1™ ballistic separator for use in shredding yards, steel mills, and slag processing facilities. It uses ballistics to upgrade frag by segregating the copper-bearing materials from the rest of the ferrous materials.

The unit delivers two distinct fractions: a low-copper ferrous product and a traditional #2 shred. In operation, material is presented to a 1,000-FPM belt and passed over a magnetic head pulley. Ferrous with low copper content sticks to the magnetic pulley and is dragged behind the splitter. Larger materials—which are less magnetic because of size, shape, and copper content—are influenced more by the speed of the belt than the attraction of the magnet and, therefore, get thrown over the splitter.

The low copper, or #1 shred, is about 75 percent of the total material volume. It goes directly to a stacking conveyor without going through a picking conveyor. The #2 fraction, high copper, is the other 25 percent of the total material. It goes through a manual picking station to pick copper-bearing material.
