Sanitary Round Grate Magnet – 300mm Diameter | Minimum 10,000 Gauss | Fully Welded

The Sanitary Round Grate Magnet – 300mm Diameter | Min 10,000 Gauss | Fully Welded is a high-strength industrial magnetic separation system designed to capture and remove unwanted ferrous metal contamination from powders, granules and other compatible free-flowing materials. Featuring a 300mm round grate design, a magnetic field strength of at least 10,000 Gauss, and fully welded construction, this magnetic grate is suited to processing environments where effective contamination control and hygienic equipment design are important.

The grate incorporates multiple high-strength magnetic separator bars positioned across the product flow. As material passes through and around the magnetic tubes, susceptible iron and steel particles are attracted to the magnetic surfaces and retained for removal, helping protect downstream machinery and reduce ferrous contamination in the finished product.

Its fully welded sanitary construction eliminates detachable joints within the grate assembly, creating a robust, integrated magnetic separator suitable for demanding industrial processing applications.

How Does a Round Grate Magnet Work?

A magnetic grate, also known as a grate magnet, magnetic grid or hopper magnet, uses multiple magnetic separator bars arranged across the path of a product stream.

As compatible material passes through the grate, it is forced to travel close to the magnetic tubes. Magnetically susceptible iron and steel contamination is attracted away from the product stream and retained on the surfaces of the separator bars.

Using multiple bars across the 300mm round grate provides broader magnetic coverage than a single separator tube and reduces the pathways through which material can pass without approaching a magnetic surface.

Minimum 10,000 Gauss Magnetic Strength

This sanitary grate magnet provides a magnetic field strength of at least 10,000 Gauss, delivering high-intensity magnetic separation for demanding contamination-control applications.

A high-strength magnetic field can help capture fine ferrous particles and fragments from compatible product streams, supporting product purity and helping protect downstream machinery.

The stated minimum 10,000 Gauss refers to magnetic field strength and should not be interpreted as a lifting capacity or pull-force rating.

Fully Welded Sanitary Construction

The fully welded design creates a robust, integrated grate assembly without removable mechanical connections between the separator bars and surrounding frame.

This construction is particularly useful in processing environments where equipment durability, cleanability and minimising potential product-trap areas are important considerations.

The round 300mm format also makes the grate suitable for integration into compatible circular hoppers, processing vessels, chutes and product-flow systems.

Always confirm the dimensions, materials and sanitary requirements of the complete installation before incorporating the grate into food, pharmaceutical or other regulated processing equipment.

Magnetic Separation for Processing Equipment

The 300mm sanitary round grate magnet can be positioned within compatible product-flow systems so bulk material passes directly across the magnetic separator bars.

Potential installation locations include:

• Hoppers
• Chutes
• Product inlets
• Processing vessels
• Gravity-fed systems
• Bulk material transfer points
• Custom magnetic separation equipment

Correct placement is important because magnetic attraction decreases rapidly with distance. For effective separation, the system should encourage material to pass close to the magnetic surfaces.

Benefits of Magnetic Grate Separation

Correctly installed magnetic grate separators can help:

• Capture unwanted iron and steel particles
• Reduce ferrous contamination in processed materials
• Capture fine magnetically susceptible particles
• Improve product and material purity
• Protect downstream machinery from metal fragments
• Reduce the risk of equipment damage
• Support contamination-control procedures
• Provide continuous magnetic separation without electrical power

The permanent magnetic system operates without an external power supply, making it a straightforward solution for compatible processing lines.

Cleaning and Maintenance

Captured ferrous contamination should be removed from the magnetic grate regularly to maintain effective separation performance.

Cleaning frequency will depend on the amount of product being processed and the level of ferrous contamination present. Excessive accumulation of captured metal can reduce the available magnetic collection surface and affect separation efficiency.

Before cleaning, maintenance or removal, isolate the grate from product flow and surrounding machinery according to applicable workplace and site-specific procedures.

Take care when removing captured ferrous particles, as the minimum 10K Gauss magnetic field can hold iron and steel contamination firmly against the separator bars.

Please Note

The stated minimum 10,000 Gauss rating refers to magnetic field strength and is not a pull-force or lifting capacity rating.

Actual magnetic separation performance depends on factors including contaminant size, shape and magnetic properties, product characteristics, material depth, flow rate, installation geometry and distance from the magnetic surfaces.

This grate magnet is primarily designed to capture magnetically susceptible ferrous contamination. Non-magnetic materials such as aluminium, copper, brass, plastic and many stainless steel grades will not be effectively captured.

For use in food, pharmaceutical or other regulated sanitary applications, the complete installation should be assessed against the applicable hygiene, material, certification and cleaning requirements for the specific facility and process.

Strong magnetic fields may affect pacemakers, medical implants, magnetic storage media and sensitive electronic equipment.
