The deferrizing groups – def are specifically designed to separate non-ferrous electro-conductive metallic materials from inert materials, i.e., non-electro-conductive materials. Through an advanced system, the machine is able to identify and expel metals such as aluminum, copper, and brass from the main material flow. The use of deferrizing groups – def ensures high purity of the final product by precisely separating all non-conductive components, thus protecting the integrity of downstream production processes.
