An overbelt magnetic separators is employed when a large amount of Ferrous inert is present in the waste flow.
This type of separator extracts and expels ferrous intrusions, ensuring optimal product cleaning and freedom of use for the machine operator.
These separators do not need an electrical panel. They are supplied ready for installation and operation thanks to a direct connection to an electric motor.
An overbelt magnetic separator is used in the first stage of refining the process material such as glass, wood, plastic, post-combustion slag, USW, OFMSW, etc.
An overbelt separator is made up of:
The magnet enclosed within the separator generates a magnetic field directed towards the conveyor belt beneath. The Ferrous material is attracted by the magnet and thus removed from the material flow.
The extractor belt of the separator is equipped with transversal cleats that push the attracted ferrous tramp metal towards the discharge point. Here, the intensity of the magnetic field gradually reduces facilitating metal release.
The attraction force varies depending on many factors such as:
An overbelt separator is typically mounted or suspended over a conveyor belt or a vibrating feeder. It can be installed either transversally the material flow (cross-wise) or parallel to it (in-line).
There are two types of permanent magnets which generate magnetic fields of different intensities.
Depending on the aspect above mentioned, the overbelt separators can be built with:
