What Is a Suspension Plate Magnet?

A suspension plate magnet is a permanent magnetic separation device positioned above or near a compatible moving material stream.

As bulk material travels beneath or past the magnetic plate, magnetically susceptible iron and steel contaminants entering the magnetic field are attracted towards the plate and retained on its magnetic surface.

Potential contaminants may include:

• Tramp iron
• Nails
• Screws
• Nuts and bolts
• Steel wire
• Ferrous offcuts
• Steel fragments
• Equipment wear particles
• Other magnetically susceptible metal contamination

Captured ferrous material can then be periodically removed as part of the system's cleaning and maintenance procedure.

250mm x 400mm x 120mm Design

The plate magnet has overall supplied dimensions of 250mm x 400mm x 120mm, providing a substantial magnetic separator assembly for compatible industrial processing systems.

Its dimensions make it suitable for integration into applications such as:

• Conveyor lines
• Gravity chutes
• Material transfer points
• Processing equipment
• Recycling lines
• Bulk handling systems

The required plate size should be selected according to the material stream, conveyor or chute dimensions, installation geometry and expected contamination.

NdFeB Rare Earth Magnetic System

This suspension plate magnet incorporates Neodymium Iron Boron (NdFeB), a high-performance rare earth permanent magnetic material.

NdFeB is known for producing powerful magnetic fields relative to its size and is widely used where high magnetic performance is required within industrial equipment.

Potential advantages include:

• Strong permanent magnetic fields
• Continuous magnetic operation
• No electrical power required for attraction
• No electromagnet coils to energise
• Suitable for industrial ferrous contamination removal

A specific neodymium magnetic grade has not been supplied and should not be assumed.

How Does a Suspended Plate Magnet Work?

The plate magnet produces a permanent magnetic field extending away from its active surface.

In a typical material-handling application:

1. Material travels along a conveyor or through a chute.
2. The plate magnet is suspended at an appropriate position relative to the material stream.
3. Magnetically susceptible iron or steel enters the magnetic field.
4. Ferrous contamination is attracted towards the plate.
5. Captured material remains on the magnetic surface.
6. The accumulated contamination is periodically removed using an appropriate cleaning procedure.

The efficiency of separation depends on the characteristics of both the contaminant and the complete processing system.

Ferrous Contamination Removal

The Plate Magnet is designed primarily to capture magnetically susceptible iron and steel contamination.

This may include:

• Steel fragments
• Iron pieces
• Nuts and bolts
• Screws
• Nails
• Wire
• Ferrous offcuts
• Processing-equipment wear debris
• Tramp metal

Removing these materials from the product stream can assist with product quality and reduce the risk of ferrous objects reaching downstream processing machinery.

Protecting Downstream Equipment

Unwanted steel and iron contamination can potentially damage industrial processing equipment.

Depending on the installation, a suspension magnet may help protect:

• Crushers
• Grinders
• Mills
• Shredders
• Conveyors
• Processing machinery
• Pumps
• Packaging systems
• Production equipment

Positioning magnetic separation upstream of vulnerable equipment can form part of a broader equipment-protection and contamination-control strategy.

Magnetic Attraction Decreases with Distance

The distance between the magnetic plate and the ferrous contaminant is a critical factor in separation performance.

Magnetic attraction decreases rapidly with distance.

Installation should therefore be designed to bring potential contaminants sufficiently close to the effective magnetic field while maintaining appropriate clearance from the product stream and moving equipment.

Performance can be influenced by:

• Suspension height
• Material-bed depth
• Conveyor speed
• Contaminant size
• Contaminant shape
• Contaminant weight
• Magnetic susceptibility
• Contaminant orientation
• Material density
• Installation geometry

Conveyor and Chute Installation

Suspended plate magnets can be integrated into compatible material-handling equipment at strategic points where ferrous contaminants are likely to pass through the magnetic field.

Potential locations include:

• Above conveyor belts
• Chute systems
• Material discharge points
• Transfer points
• Gravity-fed processing systems
• Bulk handling equipment

The optimum installation location depends on the specific equipment, material characteristics and contamination-control requirements.

Permanent Magnetic Operation

This NdFeB plate magnet uses a permanent magnetic system, meaning it does not require electrical power to generate its magnetic field.

There is no requirement for:

• Electrical wiring to energise the magnet
• Continuous electrical power
• Batteries
• Magnetic coils
• Electromagnet controllers

The magnetic field remains continuously active, including during installation, cleaning and maintenance.

Magnetic Separation Performance

Actual separation performance depends on more than the physical size of the magnet.

Important factors include:

• Contaminant magnetic properties
• Contaminant size and shape
• Contaminant weight
• Material characteristics
• Product depth
• Conveyor speed
• Suspension distance
• Material-flow behaviour
• Installation geometry
• Surrounding steel structures
• Cleaning frequency

No specific Gauss rating or pull force has been supplied for this plate magnet and magnetic performance should not be inferred solely from its dimensions or NdFeB construction.

Ferrous vs Non-Ferrous Materials

This magnetic separator is designed for ferromagnetic iron and steel.

It will not effectively capture non-magnetic materials such as:

• Aluminium
• Copper
• Brass
• Plastic
• Timber
• Glass

Many stainless steel grades may also provide little or no magnetic attraction.

Where non-ferrous metal separation is required, other detection or separation technologies may be necessary.

Recycling and Industrial Applications

Suspension plate magnets can be useful wherever compatible bulk material needs to be inspected for unwanted ferrous contamination.

Potential applications include:

• Recycling materials
• Plastic feedstocks
• Manufacturing raw materials
• Waste streams
• Industrial feed materials
• Mineral processing
• Bulk products
• Production materials

Suitability should be assessed according to the material being processed and the characteristics of the contamination being targeted.

Installation Considerations

Correct installation is essential for effective and safe operation.

Consider:

• Conveyor or chute dimensions
• Material-bed depth
• Suspension height
• Conveyor speed
• Expected contaminant size and weight
• Available mounting space
• Surrounding steel structures
• Cleaning access
• Equipment movement
• Structural support

The suspension system should be designed to securely support the complete magnetic assembly.

For overhead installations, appropriate engineered mounting and secondary retention should be incorporated so accidental detachment cannot allow the plate magnet to fall onto personnel, equipment or the material-handling system.

Cleaning and Maintenance

Captured ferrous contamination should be removed periodically.

Cleaning frequency depends on:

• Contamination levels
• Material throughput
• Type and size of ferrous debris
• Processing conditions
• Production schedules

Excessive accumulation of ferrous material can reduce the available collection surface and potentially affect separation performance.

Because the NdFeB magnetic system is permanently active, appropriate equipment isolation, handling procedures and personal protective equipment should be used during cleaning.

Safety Around NdFeB Plate Magnets

Large neodymium magnetic assemblies can generate powerful attractive forces around ferromagnetic steel.

During handling, installation and maintenance:

• Keep hands clear of pinch points
• Prevent uncontrolled attraction to steel structures
• Keep unnecessary steel tools away from the magnetic surface
• Secure the magnet before operating nearby equipment
• Use suitable lifting and handling procedures for the complete assembly
• Isolate nearby machinery during maintenance
• Follow applicable workplace safety procedures

Please Note

This product is a Suspension NdFeB Plate Magnet measuring 250mm x 400mm x 120mm.

No specific Gauss rating, pull force, neodymium grade, housing material, surface finish, mounting configuration, suspension hardware, maximum operating temperature, maximum conveyor speed or recommended suspension height has been supplied and these specifications should not be assumed.

Actual separation performance depends on contaminant size, shape, weight and magnetic susceptibility, together with suspension height, material-bed depth, conveyor speed, product characteristics and installation geometry.

This magnetic separator is designed primarily for magnetically susceptible ferrous iron and steel and will not effectively capture aluminium, copper, brass or other non-ferromagnetic materials.

The plate magnet is not lifting equipment, and its magnetic attraction should not be interpreted as a safe working load. Any overhead installation must use an appropriately engineered support and secondary-retention system.

Keep powerful magnetic equipment away from pacemakers and other medical implants, magnetic storage media and sensitive electronic equipment.
