The Master Mag Heavy-Duty electro overband is the most powerful overband we manufacture. Master Magnets manufacture the widest range of this type of separator with the largest to date weighing 35 tonnes and spanning across a 2 metre wide conveyor.                                        

Due to its high magnetic strength, the overband is able to work at an increased operating gap, enabling it to extract ferrous from deep troughed conveyors and at a faster speed should customers want to increase the feed rate.

Electro magnetic overbands are commonly used for installation in plants within the quarrying and recycling industries where they would be positioned either inline over the head pulley or across a conveyor belt.

Application

Heavy-Duty Overband Magnets are used for Arduous applications, where there are high working gaps and burden depths. They can also extract finer pieces of ferrous contamination from buried product streams.

Typical example of applications are;

Models

Master Magnets supply Heavy-Duty overband magnets to operate over 150mm - 2000mm conveyor belts. For larger conveyor belt widths, overband magnets can be custom designed to suit the application. Additional support structures can also be supplied.

There are two different types of Heavy-Duty electro overbands;

1. Oil Cooled - This type of heavy-duty overband is the most commonly used of the two types. It efficiently maintains an optimum working temperature and is also capable of producing a higher force factor than the air cooled electro overband magnet.
2. Air cooled - This type of magnet is used where oil is not a customers preference for health and safety reasons. For example, a client may wish to use this type of cooling because it is less of a fire hazard. 

To give the overband magnet a longer belt life (especially when handling abrasive materials) an armoured belt can be fitted as an optional extra.

Also, heat resistant belting can also be supplied to allow the heavy-duty overband to operate at higher ambient temperatures.
