Eddy-current technique has been used in several industrial applications, such as nondestructive
testing and characterization, transmission systems, and separation processes.
The main advantage of other separation techniques for eddy current separation is the
absence of direct contact and do not use other liquid and water. This paper presents a
novel configuration for a single-disk vertical eddy current separator, covered by alternating
permanent magnets. Unlike several other works, which employ a horizontal orientation for
magnetic disks. The advantage is that it contains one driving motor, few strong permanent
magnets, and a small size and simpler construction than the usual eddy-current separators.
In this work, the analysis of an eddy current separator with magnetic single disk using a
numerical model based on finite element method, the obtained partial differential equation
is done into the numeric solver. The experimental device was realized to separate two kinds
of non-ferrous waste: aluminium and copper. The experiment results show the effect of
speed variation, metals size, and kind of metal on ejection distance.
