Sanitary Round Grate Magnet – 200mm Diameter | Min 10,000 Gauss | Fully Welded

The Sanitary Round Grate Magnet – 200mm Diameter | Minimum 10,000 Gauss | Fully Welded is a high-intensity industrial magnetic separation grate designed to capture ferrous contamination from powders, granules and other compatible free-flowing materials. With a 200mm overall diameter, a magnetic field strength of at least 10,000 Gauss (10K Gauss) and a fully welded sanitary construction, this round grate magnet is designed for integration into compatible processing and material-handling systems.

Also known as a magnetic grate, magnetic grid, hopper magnet or magnetic separator grate, this permanent magnetic separator provides multiple magnetic surfaces across the product flow. As material passes around the magnetic bars, magnetically susceptible iron and steel particles are attracted to the magnetic surfaces and retained for removal during cleaning.

Its combination of minimum 10K Gauss magnetic performance and fully welded construction makes this 200mm round magnetic grate suitable for contamination-control applications across food and ingredient processing, pharmaceutical manufacturing, plastics, chemical processing, powder handling and other industrial environments where effective ferrous separation and cleanable construction are important.

Minimum 10,000 Gauss Magnetic Field Strength

This sanitary grate magnet provides a specified magnetic field strength of at least 10,000 Gauss, providing a high-intensity magnetic environment for attracting magnetically susceptible ferrous contamination.

Potential contaminants may include:

• Fine iron particles
• Ferrous fragments
• Steel particles
• Rust contamination
• Ferrous swarf
• Small magnetic fasteners
• Other magnetically susceptible material

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

Actual separation performance depends on the material being processed, contaminant characteristics and the design of the complete separation system.

How Does a Round Grate Magnet Work?

A magnetic grate positions multiple magnetic collection surfaces across the path of the processed material.

As powders, granules or other compatible free-flowing materials move through the grate, they are directed around and between the magnetic bars.

When magnetically susceptible iron or steel contamination passes sufficiently close to a magnetic surface, it is attracted and retained.

The collected contamination remains on the grate until it is removed during cleaning.

This multi-bar arrangement increases opportunities for ferrous contaminants to enter the effective magnetic field compared with relying on a single magnetic separator bar.

200mm Round Grate Design

The 200mm diameter round format is designed for integration into compatible circular processing equipment and material-flow systems.

Potential installation points can include:

• Round hoppers
• Chutes
• Product inlets
• Transfer points
• Processing vessels
• Gravity-fed systems
• Custom separation equipment

Before installation, confirm that the 200mm grate diameter and overall construction are compatible with the intended equipment and product-flow requirements.

Fully Welded Sanitary Construction

The fully welded construction provides a robust grate assembly designed for processing environments where durability and cleanability are important considerations.

Compared with assemblies containing numerous removable joints or separate structural components, a fully welded grate provides an integrated construction that can simplify routine handling and cleaning.

This design can be particularly beneficial in processing environments where contamination-control equipment needs to be regularly inspected and cleaned.

Where the grate is intended for a regulated sanitary application, the suitability of the complete product specification, materials, surface finish, fabrication and cleaning procedures should be confirmed against the applicable requirements.

Magnetic Separation in Processing Systems

Round grate magnets are commonly installed at strategic points where product can pass directly through or around the magnetic assembly.

Depending on the processing system, suitable locations may include:

• Before sensitive downstream machinery
• Inside hoppers
• At product discharge points
• Within gravity-fed processing lines
• At ingredient transfer locations
• Before packaging or additional processing stages

The ideal installation position depends on the material being processed, equipment configuration and contamination-control objectives.

Food, Ingredient and Industrial Processing

High-intensity magnetic grate separators are useful in processing applications where unwanted ferrous material may enter raw ingredients, powders, granules or manufactured products.

Potential industries include:

• Food production
• Ingredient processing
• Pharmaceutical manufacturing
• Plastics processing
• Chemical manufacturing
• Powder processing
• Bulk material handling
• General manufacturing

Depending on the system design, the grate can help capture ferrous contamination before it reaches downstream equipment or later stages of production.

Factors Affecting Magnetic Separation Performance

The minimum 10,000 Gauss field strength is an important magnetic specification, but it is not the only factor determining separator performance.

Actual ferrous capture depends on factors including:

• Contaminant size
• Contaminant shape
• Magnetic susceptibility
• Product characteristics
• Material flow rate
• Product depth
• Distance from the magnetic surface
• Installation geometry
• Distribution of material across the grate
• Amount of accumulated ferrous contamination

Magnetic attraction decreases rapidly with distance, so effective system design should encourage the processed material to pass close to the magnetic surfaces.

Cleaning and Maintenance

Captured ferrous contamination should be removed regularly to maintain effective separation.

The appropriate cleaning frequency depends on contamination levels, product throughput and the processing environment.

During cleaning and inspection:

• Follow applicable equipment isolation procedures
• Carefully remove accumulated ferrous contamination
• Inspect magnetic surfaces for damage or excessive wear
• Inspect the welded assembly
• Keep magnetic surfaces clean
• Confirm the grate is correctly repositioned before restarting equipment

Allowing excessive ferrous material to accumulate on the magnetic surfaces can reduce the effectiveness of the separator.

Please Note

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

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

The term sanitary and the fully welded construction should not by themselves be interpreted as certification for a particular food, pharmaceutical or regulatory standard. Where the grate will be used in a regulated process, confirm the material grade, surface finish, fabrication details, installation method and applicable compliance requirements for the specific application.

Actual magnetic separation performance depends on contaminant properties, material flow, installation geometry, distance from the magnetic surfaces and cleaning frequency.

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