What Is a Suspension Plate Magnet?

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

As material travels beneath or past the magnetic plate, magnetically susceptible iron and steel objects entering the magnetic field are attracted towards the plate rather than continuing with the product stream.

Depending on the application, captured contamination may include:

• Nails
• Screws
• Nuts and bolts
• Steel fragments
• Ferrous offcuts
• Wire
• Iron particles
• Equipment wear fragments
• Other magnetically susceptible tramp metal

The captured material can then be periodically removed from the plate according to the operating and cleaning procedure of the installation.

400mm x 400mm Magnetic Coverage

The plate magnet measures 400mm x 400mm across its primary dimensions, providing a broad magnetic area for integration into compatible material-handling systems.

This format can be useful where magnetic separation is required across:

• Conveyor belts
• Material chutes
• Transfer points
• Processing lines
• Gravity-fed material streams
• Bulk handling equipment

The 120mm dimension forms part of the overall supplied dimensions of the magnetic assembly.

The suitability of these dimensions for a particular conveyor or chute should be assessed against the width, depth and flow characteristics of the material stream.

NdFeB Rare Earth Magnetic System

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

NdFeB magnets are known for producing powerful magnetic fields relative to their size, making them useful for demanding industrial magnetic separation applications.

Potential advantages of an NdFeB plate magnet include:

• Strong permanent magnetic fields
• No electrical power required for magnetic attraction
• Continuous magnetic operation
• High magnetic performance relative to magnet volume
• Suitable for industrial ferrous separation
• No electromagnet power consumption

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

How Does a Suspended Plate Magnet Work?

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

In a typical conveyor application:

1. Bulk material travels along a conveyor or through a chute.
2. The plate magnet is positioned at an appropriate distance from the material stream.
3. Magnetically susceptible iron and steel contamination enters the magnetic field.
4. Ferrous material is attracted towards the magnetic plate.
5. Captured contamination remains attached to the magnetic surface.
6. The accumulated ferrous material is periodically removed during an appropriate cleaning procedure.

The effectiveness of this process depends strongly on the distance between the magnetic plate and the contamination.

Magnetic Attraction Decreases with Distance

Magnetic attraction decreases rapidly as the distance from the magnetic surface increases.

Installation height is therefore an important consideration when designing a suspended magnetic separation system.

Performance can be affected by:

• Distance from the material stream
• Depth of material on the conveyor
• Conveyor speed
• Contaminant size
• Contaminant weight
• Contaminant shape
• Magnetic susceptibility
• Orientation of the contaminant
• Material density
• Installation geometry
• Obstructions between the magnet and contaminant

The plate should be positioned according to the requirements of the specific processing system while maintaining safe clearance from moving material and equipment.

Ferrous Contamination Removal

This plate magnet is designed to attract magnetically susceptible iron and steel contamination.

Potential contaminants include:

• Tramp iron
• Steel fragments
• Nuts
• Bolts
• Screws
• Nails
• Wire
• Ferrous offcuts
• Processing-equipment wear debris
• Other magnetic steel objects

Removing this contamination can assist with both product purity and downstream equipment protection.

Protect Downstream Processing Equipment

Unwanted ferrous material can damage or interfere with downstream equipment.

Depending on the processing system, magnetic separation may help protect equipment such as:

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

Capturing tramp iron before it reaches sensitive machinery can form an important part of an industrial contamination-control strategy.

Conveyor and Material Handling Applications

Suspension plate magnets are particularly useful in systems where bulk material moves continuously beneath a fixed magnetic separator.

Potential material-handling applications include:

• Conveyor belts
• Gravity chutes
• Transfer points
• Hoppers
• Feed systems
• Recycling lines
• Processing lines

The correct installation arrangement depends on the equipment and material being processed.

Permanent Magnetic Operation

The NdFeB magnetic system is permanent, meaning electricity is not required to create the magnetic field.

There is no requirement for:

• Electrical wiring to energise the magnet
• Continuous electrical power
• Magnetic coils
• Power-control equipment
• Battery charging

This can simplify installation compared with electrically energised magnetic separators.

The magnetic field remains active at all times and should therefore be considered during installation, cleaning, maintenance and storage.

Magnetic Separation Performance

Actual separation performance depends on the complete installation rather than the magnet dimensions alone.

Important factors include:

• Contaminant material
• Ferrous content
• Contaminant size and shape
• Contaminant weight
• Material-bed depth
• Conveyor speed
• Installation height
• Magnetic orientation
• Product characteristics
• Material-flow behaviour
• Cleaning frequency
• Surrounding steel structures

No specific Gauss rating or pull force has been supplied for this product and magnetic performance should not be inferred solely from the 400mm x 400mm x 120mm dimensions or NdFeB construction.

Non-Ferrous Materials

Magnetic plate separators are intended primarily for ferromagnetic iron and steel.

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

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

Many stainless steel grades may also provide weak or negligible magnetic attraction.

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

Recycling and Manufacturing Applications

In recycling and manufacturing environments, a suspended plate magnet can assist with removing ferrous contamination from compatible material streams.

Potential applications include:

• Recycling materials
• Plastic feedstock
• Manufacturing raw materials
• Processed materials
• Waste streams
• Bulk products
• Industrial feed materials

Suitability should be assessed according to the physical properties and flow characteristics of the material being processed.

Installation Considerations

Correct installation is critical to magnetic separation performance.

Consider:

• Conveyor or chute width
• Material-bed depth
• Distance from the material
• Conveyor speed
• Expected contaminant size
• Surrounding steel structures
• Available mounting space
• Required cleaning access
• Dynamic equipment movement
• Structural support

The magnetic plate and its support system should be securely installed so that it cannot detach or interfere with moving equipment.

Where the magnet is suspended above a conveyor or work area, the complete suspension structure should be appropriately engineered and independently secured for the application.

Cleaning and Maintenance

Captured ferrous contamination should be removed regularly.

Cleaning frequency will depend on:

• Contamination levels
• Material throughput
• Type of ferrous debris
• Operating environment
• Production schedule

Excessive accumulation of steel on the magnetic surface may reduce available collection area and affect separation efficiency.

Because this is a permanent magnet, the magnetic field remains active during cleaning. Appropriate isolation procedures and personal protective equipment should be used.

Safety Around Powerful NdFeB Magnets

Large neodymium magnetic assemblies can generate substantial attractive forces when brought near ferromagnetic steel.

During handling and installation:

• Keep hands clear of potential pinch points
• Prevent uncontrolled contact with large steel objects
• Use appropriate handling procedures
• Secure the assembly before operation
• Keep unnecessary ferromagnetic tools away from the magnetic surface
• Follow workplace lifting and handling procedures
• Isolate nearby machinery before maintenance or cleaning

Please Note

This product is a Suspension NdFeB Plate Magnet measuring 400mm 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 magnetic separation performance depends on contaminant size, shape, weight and magnetic susceptibility, together with installation height, material-bed depth, conveyor speed, product characteristics and system geometry.

This product is intended for capturing magnetically susceptible ferrous iron and steel. It will not effectively separate aluminium, copper, brass and other non-ferromagnetic materials.

The plate magnet itself should not be treated as lifting equipment or assigned a safe working load based on its magnetic attraction. Any overhead or suspended installation must use a suitably engineered mounting and secondary-retention system appropriate to the application.

Powerful magnetic fields can attract steel objects unexpectedly. Keep the magnet away from pacemakers and other medical implants, magnetic storage media and sensitive electronic equipment.
