MSA RARE EARTH MAGNETIC HEAD PULLEYS!

With up to 4 times more power than commonly available Ceramic/Ferrite Pulleys, our Australian Made Rare Earth Pulleys are changing the face of Metal Separation in Australia.

The 4000-6000 Gauss surface intensity makes this option suitable for many applications where product purity and machine protection are both required, for example, Hay Processing and Rock Crushing, or where high-tonnage is being processed with low-density metal contamination, for example, Glass Recycling Plants.

For efficient extraction of ferrous and tramp metals from conveyed product streams.

Suited to non-food related industries such as recycling and mining, overbelt and suspension magnets offer a safe, efficient, and effective method of removing ferrous tramp and iron pieces. The magnets are installed above conveyed product streams and extract contaminating ferrous and tramp metal as the belt proceeds past – thus improving product purity and reducing equipment damage.

Commonly extracted ferrous contaminants from these types of installations include nails, screws, nuts, bolts, wire, chain, hammers, and crowbars – all of which can cause thousands of dollars in equipment damage if not removed early in the process.

Installation:

Overbelt and suspension magnets can be installed over the top of the conveyor (cross-belt style) or at the end of the conveyor at discharge location (inline style).

ELECTRO OR PERMANENT MAGNETS

Overbelt and suspension magnets are available in either permanent magnetic or electromagnetic designs. Each design has its own benefits and can include quick or self-cleaning methods.

 

ADVANTAGES OF ELECTRO-MAGNETS ADVANTAGES OF PERMANENT MAGNETS
  • Stronger magnetic field
  • Easy to clean
  • Can handle a heavier burden of material
  • Suited to high-tonnage, fast-flowing belts
  • Suited to deep troughed conveyors
  • Less expensive than electromagnets
  • Low install & operating costs
  • No power source required to operate
  • No electrical maintenance

 

OVERBELT MAGNETS

Overbelt Magnets consist of a magnet box surrounded by a continuously moving belt. The magnet is installed above the product stream conveyor, either mid-stream or at the conveyor discharge. As the product stream travels under the overbelt magnet, ferrous and tramp iron pieces are extracted and retained to the magnetic belt. The belt proceeds around the overbelt magnet housing. When it reaches the point at which it is no longer affected by the magnetic field, the collected metal is discharged and dropped off into collection bins.

Overbelt Magnets are popular due to their self-cleaning operation, which allows interrupted metal extraction and eliminates the need for operator cleaning schedules. They are also suited to applications where the typical level of ferrous contamination is high.

 

SUSPENSION MAGNETS

Suspension Magnets are a much simpler design than Overbelt Magnets. They consist of a block magnet (square, rectangular, or round) suspended above the conveyor with chains. The magnet face is positioned directly above the product stream, either cross-belt or inline (above conveyor discharge).

Regardless of whether Suspension Magnets are of permanent or electromagnetic design, there is usually manual labor involved in the cleaning process. The magnet must be shifted away from the conveyor before the collected metal is removed, otherwise, it may drop back into the product stream and cause recontamination. Because this manual labor is required, Suspension Magnets are typically selected for applications where the level of ferrous contamination is low and only occasional cleaning is required.

 

MAGNETIC PULLEYS

MSA also supply complete new magnetic pulley systems and magnetic pulley lagging for existing pulley magnets. These systems are installed at the discharge terminus of a conveyor and are used to effectively separate magnetic contaminants from the main non-magnetic product stream.
