The magnetic separator for cans and cartons *(R-SLB) is a classification device that processes the material flow consisting of cans and cartons, previously separated from the general flow of MSW (Municipal Solid Waste) using an Eddy Current separator. The cans are more influenced and are propelled forward, being clearly separated from the cartons.
*Carton refers to the composite of cardboard + aluminum + plastic used in packaging, commonly used for beverages.
Introduction to the Magnetic Separator for Cans and Cartons
Metals, both ferrous and non-ferrous, form one of the material groups most considered in waste reduction, as they represent a high value. The most important non-ferrous metal is aluminum, which is most commonly found in MSW (Municipal Solid Waste) in the form of cans and cartons (*). Aware of the severe environmental problem, we have developed a complete range of equipment for magnetic separators for cans and cartons by Eddy Current (R-SLB) - equipment patented by Regulator-Cetrisa – aimed at achieving the separation, recycling, and recovery of these in separate fractions.
Physical Principle of Magnetic Separation of Cans and Cartons by Eddy Current
The physical principle of Eddy Currents is based on an alternating magnetic field, that is, a magnetic field where the North and South poles change alternately.
Let's consider a simple magnet. The lines of force that generate the magnetic field close from one magnetic pole to the other (N-S). If we place a ferrous metal within the lines of force, they will attract it towards the magnet.
