Square Grate Magnet – 260mm x 260mm | Minimum 10,000 Gauss

The Square Grate Magnet – 260mm x 260mm | Minimum 10,000 Gauss is a high-intensity industrial magnetic separator designed to capture magnetically susceptible ferrous contamination from compatible powders, granules and other free-flowing materials. Measuring 260mm x 260mm, this square magnetic grate provides a minimum magnetic field strength of 10,000 Gauss, making it suitable for contamination-control applications across food and ingredient processing, pharmaceutical manufacturing, plastics, chemical processing, manufacturing and bulk material handling.

The grate configuration positions magnetic separator tubes across the material-flow path so product passes around and close to the magnetic surfaces. Magnetically susceptible iron and steel particles are attracted towards the magnetic tubes and retained for removal, helping reduce unwanted ferrous contamination within the processed material.

The 260mm square format is particularly suited to compatible square or rectangular hoppers, chutes, bins and processing openings where broad magnetic coverage is required.

Minimum 10,000 Gauss Magnetic Field Strength

This grate magnet provides a specified magnetic field strength of at least 10,000 Gauss.

Gauss measures magnetic flux density or magnetic field strength at a particular measurement point. A minimum 10,000 Gauss rating provides a high-intensity magnetic field at the specified measurement location for attracting magnetically susceptible ferrous contamination that passes sufficiently close to the magnetic surface.

The 10,000 Gauss specification is a magnetic field-strength measurement and should not be interpreted as a pull-force, lifting-capacity or safe-working-load rating.

Why Use a 10,000 Gauss Grate Magnet?

High-intensity magnetic separation can be particularly useful in processing environments where unwanted ferrous particles need to be removed from a product stream.

Potential benefits include:

• Capturing magnetically susceptible iron and steel contamination
• Reducing ferrous contamination in processed materials
• Helping protect downstream equipment
• Supporting product-quality procedures
• Providing continuous magnetic separation
• No electrical power required for magnetic attraction
• Reusable contamination-control equipment

Actual separation efficiency depends on the complete system design and the characteristics of the material and contaminant.

How Does a Square Grate Magnet Work?

A square grate magnet places multiple magnetic separator surfaces across a material-flow path.

During operation:

1. Powder, granules or another compatible material enters the grate area.
2. Material flows around and between the magnetic separator tubes.
3. Magnetically susceptible iron and steel particles enter the magnetic field.
4. Ferrous contamination is attracted towards the magnetic surfaces.
5. Captured particles remain on the magnetic tubes.
6. Accumulated contamination is periodically removed during cleaning.

This configuration helps expose a larger proportion of the product stream to magnetic surfaces than a single separator bar used independently.

260mm x 260mm Square Coverage

The 260mm x 260mm dimensions provide a square footprint for integration into compatible processing equipment.

Potential installation locations include:

• Square hoppers
• Rectangular hoppers
• Chutes
• Processing bins
• Gravity-fed systems
• Material transfer points
• Powder-processing equipment
• Granule-processing systems

The grate should be selected and installed so that material is directed around the magnetic surfaces rather than bypassing the separator.

Ferrous Contamination Capture

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

Potential contaminants may include:

• Iron particles
• Ferrous fines
• Steel fragments
• Metal filings
• Small steel particles
• Equipment wear debris
• Ferrous contamination introduced during manufacturing or handling

Captured contamination can then be removed from the magnetic surfaces as part of a scheduled cleaning and inspection process.

Magnetic Attraction Decreases with Distance

Magnetic attraction decreases rapidly with distance from the magnetic surface.

For effective separation, potential contaminants need to pass sufficiently close to the magnetic tubes.

Performance can be affected by:

• Product depth
• Material-flow rate
• Grate configuration
• Separator-bar spacing
• Contaminant size
• Contaminant shape
• Magnetic susceptibility
• Product characteristics
• Distance from the magnetic surface
• Installation geometry
• Material buildup

A well-designed installation should encourage the material stream to pass around and close to the magnetic surfaces.

Magnetic Separation Performance

The minimum 10,000 Gauss magnetic field is an important characteristic, but Gauss alone does not determine the overall effectiveness of a magnetic separation system.

Actual performance depends on factors including:

• Ferrous contaminant size
• Contaminant shape
• Magnetic properties
• Material characteristics
• Particle size
• Material-flow behaviour
• Product depth
• Flow rate
• Separator geometry
• Proximity to the magnetic surfaces
• Cleaning frequency

The grate should therefore be considered as part of the complete magnetic separation system, rather than evaluating performance from the Gauss value alone.

Permanent Magnetic Operation

The Square Grate Magnet uses a permanent magnetic system, providing continuous magnetic attraction without an external electrical supply.

There is no requirement for:

• Batteries
• Charging
• Electrical wiring
• Powered magnetic coils
• Continuous electrical power

The magnetic field remains active during operation, cleaning, maintenance and storage.

Food and Ingredient Processing Applications

Grate magnets are commonly incorporated into compatible food and ingredient-processing equipment to assist with ferrous contamination control.

Potential applications may include:

• Flour
• Sugar
• Grain
• Spices
• Dry ingredients
• Powders
• Granular products
• Other compatible free-flowing materials

For food-contact applications, verify that the complete grate assembly meets the required material, surface-finish, fabrication, cleaning, hygiene and HACCP or regulatory requirements for the specific processing environment.

Pharmaceutical and Chemical Processing

Magnetic grate separators may also be incorporated into compatible pharmaceutical and chemical material-handling systems.

Potential applications include:

• Dry powders
• Granulated materials
• Raw ingredients
• Processing feedstocks
• Compatible chemical products

Where the grate is used in a regulated or chemically demanding environment, confirm the construction materials, chemical compatibility, surface finish and cleaning requirements before installation.

Plastics and Manufacturing Applications

The 260mm Square Grate Magnet can also be used in compatible industrial systems handling materials such as:

• Plastic pellets
• Polymer granules
• Manufacturing feedstocks
• Industrial powders
• Raw materials
• Recycling materials

Magnetic separation can help remove unwanted ferrous fragments before they reach downstream production equipment.

Protecting Downstream Equipment

Ferrous contamination can potentially damage or interfere with downstream machinery.

Depending on the processing system, grate magnets may help protect:

• Mills
• Grinders
• Mixers
• Extruders
• Pumps
• Packaging machinery
• Processing equipment
• Production machinery

Removing magnetic contamination upstream can form part of a broader equipment-protection and product-quality strategy.

Ferrous vs Non-Ferrous Materials

This magnetic grate is designed primarily for ferromagnetic iron and steel.

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

• Aluminium
• Copper
• Brass
• Plastic
• Glass

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

Where non-ferrous contamination needs to be identified or removed, additional separation or detection technologies may be required.

Installation Considerations

Before installation:

• Confirm the 260mm x 260mm dimensions suit the processing equipment
• Ensure the grate is securely supported
• Position it so material flows around the magnetic surfaces
• Minimise opportunities for product to bypass the magnetic tubes
• Consider material depth and flow rate
• Provide suitable access for inspection and cleaning
• Consider the expected contaminant size and concentration
• Establish an appropriate cleaning schedule

Installation geometry can significantly influence magnetic separation performance.

Cleaning and Maintenance

Captured ferrous material should be periodically removed from the grate.

Cleaning frequency depends on:

• Contamination levels
• Product throughput
• Material characteristics
• Processing conditions
• Quality-control requirements

Excessive buildup of ferrous material can reduce the available magnetic surface and may affect subsequent contamination capture.

Appropriate equipment isolation procedures and personal protective equipment should be used during cleaning and maintenance.

Please Note

This product is a Square Grate Magnet measuring 260mm x 260mm with a specified minimum magnetic field strength of 10,000 Gauss.

The 10,000 Gauss specification describes magnetic field strength at the specified measurement location and is not a pull-force, lifting-capacity or safe-working-load rating.

No specific magnetic material or grade, stainless steel grade, surface finish, overall height, separator-bar diameter, number of magnetic tubes, tube spacing, maximum operating temperature or dimensional tolerance has been supplied and these specifications should not be assumed.

Actual magnetic separation performance depends on contaminant size, shape and magnetic properties, material characteristics, flow rate, product depth, grate geometry, proximity to the magnetic surfaces and cleaning frequency.

For food, pharmaceutical or other regulated applications, verify the construction materials, surface finish, fabrication, cleaning procedures and applicable compliance requirements of the complete magnetic separation system before use.

Strong magnetic equipment should be kept away from pacemakers and other medical implants, magnetic storage media and sensitive electronic equipment.
