Free-falling Electromagnetic Selector
An electromagnet is a type of magnet that produces an electric current (magnetic field) or reacts to an electric current applied to it. The free-falling electromagnetic selector (FES) is a device which uses electromagnetism to separate metals according to their different magnetic characteristics. This is especially useful in the mining and ore processing industries, where ore must be separated by physics – not just by observation.
The FES works by using a series of electromagnets in an array that runs along the length of a conveyor belt. As the material is moving along the conveyor belt, it will pass over these various electromagnets. On the magnet, there is a varying magnetic field which will cause an effect on the material.
Depending on the magnetic field, different metals will be affected in different ways. Some metals will be attracted or repelled by the electromagnetic field and thus, will be separated from the other materials on the conveyor belt. Heavier metals, such as iron ore, will be more strongly affected by the magnet than lighter metals, such as aluminum. By adjusting the strength of the fields, different metals can be separated with accuracy and efficiency.
The FES is a powerful tool for separating ores and other materials, and can be incredibly helpful in the mining and ore processing industries. The FES works quickly and efficiently, allowing manual sorting to become a thing of the past.
The FES is also an effective way to separate scrap metal from other materials as well. Scrap metal is often separated manually, which can be incredibly time consuming and tedious, and often results in human error. The FES can quickly separate scrap metal from other materials, without the risk of human error and with far greater efficiency than manual sorting.
The FES is a versatile and powerful tool for separating metals and other materials, with applications in a variety of industries. The device is fast, efficient, and reliable, making it an invaluable tool for any industry that requires precision sorting.
