How To Use Magnetic Separation In the Recycling Industry

Magnetic separation is the process in which ferrous material is separated from non-ferrous material using a magnetic force, these systems are used in several recycling processes such as glass, plastic, rubber, scrap metal, and electronic waste.

Magnetic separation technology is one of the most important, valuable, and best methods of sorting recyclable materials by harnessing the power of magnetic devices to separate ferrous and non-ferrous debris.

Why are Magnetic Separators Important for Recycling?

Magnetic Separators are amongst the most trusted machinery used to recover metal debris from a large amount of waste material. The process of separation is easy as it detaches fine particles with weak magnetic properties.

The vigorous designs provide an excellent separating effect, and the recycling industry uses magnetic separators due to their handling capacity, low maintenance, simple structures, and magnetic field intensity.

Magnetic Separators easily remove and sort magnetic materials from any non-magnetic material.

Eddy current separators and Conveyor overband separators are the most commonly used magnetic separators in the recycling industry to detect and detach ferrous debris from the production line.

Conveyor overband separators are used to separate various particles such as iron, steel, and stainless steel whereas Eddy current separators are used to remove non-ferrous particles including aluminium and copper.

Eddy Current Separators

Widely used within the recycling industry, Eddy Current Separators are designed to remove or recover non-ferrous metals such as aluminium, die-cast metal and copper from non-metallic material.

Magnet Expert’s range of eddy current separators is fully customisable and can be manufactured to your exact specifications including size, width, height, speed, depth, voltage, power supply, colour and more.

Eddy Current Separators work by repelling non-ferrous metals utilising magnetic force, enabling separation from non-conductive materials.

Materials are fed onto the conveyor belt of the Eddy Current Separator, which moves it across the magnetic rotor, this is where separation occurs. The magnetic rotor spins independently at a higher speed than the shell and belt.

When a non-ferrous metal passes over the separator, the magnet’s rotor rotates past the metal at high speed, causing eddy currents to form. This results in a magnetic field of the same polarity as the rotating magnet to be created around the metal, which leads to the metal being repelled away from the magnet, separating the two material streams.

Self-Cleaning Suspended Conveyor Overband Separator

Suspender Conveyor Separators are designed to effectively remove ferrous metals from material transport flows, ensuring processing equipment is free of ‘tramp’ metals. Operated through electromagnets, the deep-reaching coil design effectively penetrates all ferrous contaminants to ensure a clean processing line.

The belt is designed with self-discharge, allowing for the automatic removal of ferrous content and preventing the need to manually clean.

Suspended Conveyor Separators can be installed in either a Cross Belt Position where the Separator is perpendicular to the material transport flow or in an Inline Position parallel to the material transport flow.

Benefits of Magnetic Separators

Magnet Expert separation and detection systems prolong the life of processing equipment, ensuring that machinery is free of ferrous contaminants, which are not effectively extracted with traditional methods.

There is a risk of contamination at every stage of a processing line and magnets play a vital role in keeping lines contaminant-free, protecting consumers and brands alike.

Improved process productivity

Machine downtime is reduced through an efficient product flow, leading to increased productivity.

Safer processing environment

Removal of ferrous contaminants ensures machinery operates safely, minimising the risk of damage.

Increased product quality

With cleaner processing lines, products remain contaminant free ensuring the highest quality.
