English design, manufacture and installation of standard and bespoke waste recycling systems and equipment.
An Eddy Current Separator, or ECS, is a non-ferrous separator that is capable of separating domestic and industrial waste into two individual containers, separating non-ferrous metals such as aluminium and copper from non-metallic materials such as wood and plastics.
An ECS consists of a short belt conveyor that has its drive located at the return end and a high speed magnetic rotor system installed at the discharge end. The magnetic rotor, which is positioned within a separately rotating non-metallic drum, revolves in the region of 3000 rpm during operation whilst the outer drum cover rotates at the speed of the ECS belt conveyor.
As the rotor spins at these high speeds, an electric current is induced into conducting metals. This induced current produces a magnetic field, which opposes the field created by the rotor, repelling the conducting metals over a pre-positioned splitter plate. The remaining materials such as plastics, glass and other dry recyclables will simply free fall over the rotor, separating them from the repelled metals.
ECS's are increasingly used wherever separation of non-ferrous metals from a product stream can give a more valuable product, whether the end use is in recycling, waste reduction, raw material production or any other process whereby separation is beneficial.
