Magnetic Cross Belt Separator (Self Clean Type)


Send Enquiry


Cross Belt Magnetic Separators provide a true self cleaning industrial magnetic separator systems solution, for continuous separation of ferrous particles from material flowing on conveyors. These separator system uses a high strength overhead suspended plate magnet housed in a severe duty industrial conveyor operating in an inverted position.

  • Finish: All steel parts have one coat primer and two coats of high performance alkyd enamel

General Information:

CPM Series Cross Belt Magnetic Separators are used to remove tramp iron from conveyed materials by pulling the tramp upwards through the material against the force of gravity. They are very powerful magnets and are generally suspended above conveyor belts.

Incorporated is a motor-driven magnetic conveyor belt running across the face of the magnet, continuously moving the collected material away from the magnetic field. The removed material falls away from the belt once it leaves the magnetic field, making it a self cleaning suspended magnetic conveyor belt separator.

It must be stressed that overhead magnets are not metal detectors, and they will only operate on magnetic materials. They will not react to authenticate steels or non-ferrous items.

Medium Intensity Permanent Magnetic Cross Belt Separators are used where the material to be separated is large enough to get acted upon by medium magnetic fields from large distances. These separators find ease in picking up large ferrous material from around 200mm depth. However if the material size is smaller and the burden depth is larger, these separators become inefficient.

High Intensity Permanent Magnetic Cross Belt Separators are employed at locations where separation of ferrous material is required from a distance for around 300 mm. This type of separator is useful in picking p bolts and nuts, channels, angles, and metal pieces from distances.
