N35UH High-Temperature Neodymium Magnet

This separator bar incorporates N35UH grade Neodymium Iron Boron (NdFeB) magnetic material.

N35UH is a neodymium magnetic grade intended for applications requiring greater resistance to elevated operating temperatures than standard neodymium grades.

This makes the separator tube suitable for consideration in processing environments where operating temperatures may exceed those appropriate for conventional neodymium magnetic grades.

The specific maximum operating temperature has not been supplied for this finished separator bar and should not be assumed solely from the N35UH grade designation.

The actual temperature capability of the complete product can depend on:

• Magnetic material
• Internal construction
• Tube construction
• Assembly methods
• Seals or adhesives
• Installation conditions
• Exposure duration
• Operating environment

Always confirm the allowable operating temperature for the complete separator assembly before use in elevated-temperature processes.

How Magnetic Separator Bars Work

A magnetic separator bar creates a strong permanent magnetic field around the tube.

When compatible product flows through the magnetic field, unwanted ferromagnetic particles can be attracted toward the separator tube and retained on its surface.

Contamination may include:

• Iron particles
• Steel fragments
• Ferrous fines
• Small screws
• Wire fragments
• Machining debris
• Ferrous wear particles
• Other magnetic contamination

The collected material remains attracted to the separator until it is removed during the cleaning process.

Ferrous Contamination Removal

Magnetic separation can help reduce unwanted ferrous contamination introduced through:

• Raw materials
• Equipment wear
• Processing machinery
• Maintenance activities
• Fasteners
• Upstream manufacturing processes
• Handling and transportation

Separator bars are commonly installed at strategic points in a processing line where the product can pass close to the magnetic surface.

The effectiveness of magnetic separation depends on the complete system design rather than the magnetic bar alone.

Food and Ingredient Processing

Magnetic separator tubes are widely used as components in magnetic separation systems for compatible food and ingredient processing applications.

Potential applications include processing:

• Flour
• Sugar
• Grains
• Spices
• Powders
• Dry ingredients
• Granulated ingredients
• Other compatible free-flowing materials

Where this product is intended for food-contact or regulated processing environments, confirm the tube material, stainless steel grade, surface finish, fabrication method and applicable compliance requirements before installation.

No specific stainless steel grade or food-contact certification has been supplied and should not be assumed.

Pharmaceutical and Chemical Processing

Separator bars can also be incorporated into appropriately engineered pharmaceutical and chemical processing equipment to capture ferromagnetic contamination.

Potential installations include:

• Powder handling systems
• Mixing equipment
• Hoppers
• Chutes
• Material transfer points
• Processing vessels
• Custom magnetic grates

For regulated applications, the complete installation should be assessed against the required hygiene, cleanability, material compatibility and compliance standards.

Plastics and Manufacturing

Magnetic separator bars can help capture unwanted iron and steel contamination from raw materials used in plastics and general manufacturing.

Potential applications include:

• Plastic pellets
• Granules
• Powders
• Recycled materials
• Manufacturing feedstock
• Bulk raw materials

Removing ferrous contamination before downstream processing may help protect equipment and improve material cleanliness.

M6 Threaded Mounting

This separator bar is supplied with an M6 thread for integration into compatible magnetic separation equipment.

The threaded connection can assist with installation into:

• Magnetic grate frames
• Custom brackets
• Hoppers
• Chutes
• Processing equipment
• OEM separation systems

Confirm the required thread engagement and mounting arrangement before installation.

Do not overtighten or apply excessive mechanical force to the separator bar.

Building Magnetic Grates

Multiple magnetic separator tubes can be arranged in parallel to create a magnetic grate or grid separator.

A grate configuration increases the magnetic coverage across the product flow and can encourage material to pass closer to a magnetic surface.

Magnetic grates may be installed within:

• Hoppers
• Chutes
• Bins
• Material feed systems
• Processing equipment
• Bulk handling systems

The number, spacing and arrangement of separator bars should be selected according to the equipment dimensions, material characteristics and required separation performance.

Separator Bar Placement

Magnetic separation is most effective when contamination passes close to the magnetic surface.

Important system design considerations include:

• Distance between separator bars
• Product flow depth
• Product flow rate
• Material density
• Particle size
• Contaminant size
• Contaminant magnetic properties
• Installation geometry

A separator bar positioned too far from the material flow may not effectively capture contamination.

Where possible, equipment should be designed so the material passes close to or directly across the magnetic tubes.

Magnetic Performance

The magnetic performance of a separator bar depends on factors including:

• N35UH magnetic grade
• Internal magnetic circuit
• Tube wall thickness
• Distance from the magnetic material
• Contaminant size
• Contaminant composition
• Product flow rate
• Product depth
• Installation geometry
• Operating temperature

No specific surface Gauss rating has been supplied for this separator bar and a value should not be assumed from the N35UH grade alone.

The N35UH designation identifies the magnetic material grade; it does not directly state the magnetic field strength measured at the outside surface of the completed separator tube.

Gauss Rating vs Separation Performance

A Gauss measurement represents magnetic flux density at a particular measurement location.

It is not, by itself, a complete measure of separator performance.

Effective ferrous separation can also depend on:

• Magnetic field gradient
• Contaminant size
• Contaminant shape
• Magnetic properties of the contamination
• Distance from the magnetic surface
• Material flow characteristics
• Product speed
• Separator geometry
• Temperature

The complete separation system should therefore be assessed according to the actual material and contamination being processed.

What Materials Can a Separator Bar Capture?

This magnetic separator is intended to attract ferromagnetic materials, including:

• Iron
• Mild steel
• Magnetic steel
• Ferrous particles
• Compatible magnetic stainless steel grades

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

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

Many stainless steel grades are weakly magnetic or non-magnetic and may not be effectively captured.

Magnetic separation should not be relied upon to remove all forms of metallic or non-metallic contamination.

Cleaning the Separator Bar

Collected ferrous contamination should be removed periodically to maintain effective magnetic separation.

Cleaning frequency depends on:

• Contamination level
• Product throughput
• Material characteristics
• Separator location
• Processing environment

Before cleaning:

1. Stop and isolate the relevant processing equipment.
2. Follow applicable lockout and safety procedures.
3. Prevent additional material from entering the separator area.
4. Remove accumulated ferrous contamination using an appropriate method.
5. Inspect the separator tube and mounting points before returning the equipment to service.

Avoid allowing collected ferrous material to unexpectedly re-enter the product stream.

Permanent Magnetic Operation

This N35UH separator bar uses a permanent neodymium magnetic system.

It requires:

• No electricity
• No batteries
• No charging
• No external power supply

The magnetic field remains continuously active during normal use.

Where the separator is installed above or within moving machinery, ensure all mounting components are appropriately secured.

Please Note

This product is a Separator Bar Tube Magnet measuring 25mm in diameter x 100mm long with an M6 thread, incorporating N35UH grade Neodymium Iron Boron (NdFeB) magnetic material for applications requiring elevated-temperature capability.

No specific surface Gauss rating, maximum operating temperature, stainless steel tube grade, surface finish, dimensional tolerance, food-contact certification or magnetic separation efficiency has been supplied and these specifications should not be assumed.

The N35UH designation identifies the magnetic material grade and elevated-temperature classification; it does not by itself specify the maximum operating temperature of the complete separator bar or its surface Gauss reading.

Actual magnetic separation performance depends on the internal magnetic circuit, contaminant properties, product flow, distance from the magnetic surface, installation geometry and operating temperature.

For food, pharmaceutical or other regulated applications, confirm the required material grade, surface finish, hygiene requirements and compliance documentation before installation.
