Magnetic separation in the recycling industry
INTEGRATED SOLUTIONS FOR METAL SEPARATION AND SORTING IN THE RECYCLING INDUSTRY
The separation and sorting of metals is a basic task in the recycling industry that must be carried out efficiently and safely to increase plant productivity and minimise the amount of waste that ends up in a landfill or incinerated.
Methods for separating and classifying metals. Metal recycling
In most recycling plants, it will be necessary to install various types of magnetic separation throughout the entire process, from the incoming flow to the end, with the material clean and ready for processing.
At Dragoelectrónica we advise and offer a comprehensive solution, including all the steps in the treatment process of the material to be recycled and metal recycling.
Magnetic separation in the recycling of glass, wood and foundry sands
In glass recycling, this involves the automatic removal of ferrous and non-ferrous metals such as bottle sheets. In wood recycling, it involves the removal of nails and stainless metals. In metal smelting centres, the separation and sorting of ferrous, non-ferrous and stainless metals.

Detection of metals embedded in wood
Metal extraction in foundry sand recycling
Magnetic drum separator for the extraction of stainless steel
Stainless steel is an alloy of various metals containing a small amount of ferromagnetic iron, up to AISI304 quality.
Due to this peculiarity, it is important that 100% of the material flow passes in contact with the drum made of high gradation Neodymium magnets in order for it to be effective in separating any metallic particles that contain a small amount of magnetic iron. With this system, we ensure the separation of all stainless steel that may contain a stream of materials to be recycled.
Eddy current separator
Once we have extracted all the ferromagnetic particles and all particles containing stainless steel, what’s left is to separate from the process all the non-ferrous metallic elements, such as aluminium, brass or copper.
For this purpose, Dragoelectrónica proposes our eddy current separators, consisting of a high frequency electromagnetic field that induces electrical currents in the conductive materials that are in the flow of the material to be recycled. These non-ferrous metals are carried away by this electromagnetic current.
