The MAGQUIP range of permanent suspended Overband Magnets are installed above conveyor belts and used for removing unwanted contaminant tramp iron that can damage conveyor belts and downstream processing equipment and separating steel and metal product in metal reclamation and recycling operations. These overband magnet separators are also commonly found on mobile crushing and screening plants.
MAGQUIP uses, as standard, its triple pole magnet design on all overband magnets regardless of magnet size and application. The triple pole magnet design utilises a stack of permanent magnet blocks between thick carbon steel side poles and backbar. Using the correct proportion of steel for the poles generates a formidably strong magnetic field, comparable in performance to an electromagnet as certain operating gaps but without the cost and complexity of electromagnets and their associated cost of ownership.
The MAGQUIP PERMABAND triple pole magnet arrangement can be used with both Ceramic ferrite and Rare Earth (NdFeB) magnets.
These permanent suspension magnets can be installed over the head pulley in an “in-line” installation or across the belt in a “cross belt” style.
In applications with more high levels of ferrous metal/tramp metal contamination a “self-cleaning” (SC) type belt magnet is preferred using an automatic belt cleaning system for metal discharge. If the tramp iron or steel to be separated is relatively infrequent then a static or manual cleaning (MC) type with a hinged cleaning plate is used.
