Separator Bar Tube Magnet – 20mm x 240mm | M8 Thread with One Sealed End

The Separator Bar Tube Magnet – 20mm x 240mm | M8 Thread with One Sealed End is a compact magnetic separation tube designed to capture magnetically susceptible ferrous contamination from compatible powders, granules and other free-flowing materials. Measuring 20mm in diameter x 240mm in length, this permanent magnetic separator bar features an M8 threaded connection at one end and a sealed opposite end, providing a practical configuration for integration into compatible processing equipment and custom magnetic separation systems.

Also known as a magnetic separator bar, magnetic tube, magnetic filter rod or magnetic separation rod, this product attracts iron and steel particles that pass sufficiently close to its magnetic surface. Captured ferrous contamination is retained on the separator tube so it can be removed during scheduled cleaning.

The compact 20mm diameter and 240mm length make this magnetic bar suitable for space-conscious installations across food and ingredient processing, plastics, pharmaceutical manufacturing, chemical processing, manufacturing and bulk material handling, subject to the requirements of the complete system.

20mm x 240mm Magnetic Separator Tube

This separator bar measures 20mm in diameter and 240mm in length, providing a relatively compact cylindrical magnetic separation component.

Its dimensions can make it useful for installations where a conventional 25mm separator bar is too large or where processing equipment requires a smaller-diameter magnetic tube.

Potential installation locations include:

• Hoppers
• Chutes
• Product-flow channels
• Custom separator housings
• Processing equipment
• Magnetic filter assemblies
• Custom magnetic grids or frames

The suitability of the 240mm length should be assessed against the dimensions and material-flow characteristics of the processing system.

M8 Thread with One Sealed End

This magnetic separator tube incorporates an M8 threaded connection at one end, while the opposite end is sealed.

The M8 connection provides a mechanical mounting point for integration with compatible equipment, frames, housings or custom separator assemblies.

The sealed opposite end can be useful in installations where only one mounting connection is required or where the tube projects from a supporting structure.

The exact M8 thread depth and sealed-end geometry have not been supplied and should be confirmed where these dimensions are critical to installation.

How Does a Separator Bar Tube Magnet Work?

A magnetic separator bar generates a magnetic field around its cylindrical working surface.

As compatible material passes around the tube:

1. Powder, granules or other material flows past the magnetic separator.
2. Magnetically susceptible iron and steel contamination enters the magnetic field.
3. Ferrous particles are attracted towards the magnetic tube.
4. Captured contaminants remain on the separator surface.
5. Accumulated ferrous material is periodically removed during cleaning.

This allows the separator tube to provide continuous magnetic contamination capture without requiring an electrical power source.

Ferrous Contamination Capture

The separator bar is designed primarily for removing magnetically susceptible iron and steel contamination from compatible material streams.

Potential contaminants may include:

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

Removing these materials can assist with product-quality procedures and help protect downstream processing equipment.

Magnetic Attraction Decreases with Distance

The effectiveness of magnetic separation depends strongly on the distance between the contaminant and the magnetic surface.

Magnetic attraction decreases rapidly with distance.

The separator should therefore be positioned so that the material stream passes sufficiently close to the tube.

Factors that can affect separation include:

• Material depth
• Product flow rate
• Separator position
• Contaminant size
• Contaminant shape
• Magnetic susceptibility
• Installation geometry
• Distance from the magnetic surface
• Product buildup

Simply installing a magnetic bar within a system does not guarantee capture of every ferrous contaminant. Effective system design should maximise exposure of the material stream to the magnetic surface.

Compact 20mm Diameter

The 20mm diameter provides a smaller tube profile than many larger separator bars.

This can be advantageous where:

• Available installation space is restricted
• A compact magnetic separation component is required
• Existing equipment is designed around a 20mm tube
• A custom separator assembly requires smaller-diameter magnetic bars

The smaller physical diameter should not be interpreted as indicating a specific magnetic strength or separation capacity.

Permanent Magnetic Operation

This separator bar uses a permanent magnetic system, meaning magnetic attraction is continuously available without an external power supply.

There is no requirement for:

• Batteries
• Charging
• Electrical wiring
• Power outlets
• Powered magnetic coils

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

Magnetic Separation Performance

Actual separation performance depends on the complete processing system.

Important factors include:

• Magnetic field strength
• Contaminant size
• Contaminant shape
• Magnetic susceptibility
• Material characteristics
• Material-flow rate
• Product depth
• Distance from the tube
• Installation geometry
• Separator arrangement
• Cleaning frequency

No specific Gauss rating has been supplied for this product, so magnetic field strength should not be inferred from its dimensions or product type.

Ferrous vs Non-Ferrous Materials

Magnetic separator bars are designed primarily to capture ferromagnetic iron and steel.

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

• Aluminium
• Copper
• Brass
• Plastic
• Glass

Many stainless steel grades may also provide little or no magnetic attraction.

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

Food and Ingredient Processing

Magnetic separator tubes can be incorporated into compatible food and ingredient-processing equipment to assist with ferrous contamination control.

Potential applications may include processing:

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

For food-contact applications, the suitability of the complete magnetic separator assembly should be verified for the relevant hygiene, material, surface-finish, fabrication, cleaning and HACCP requirements.

A specific stainless steel grade or food-contact certification has not been supplied for this separator bar and should not be assumed.

Plastics, Chemical and Manufacturing Applications

Separator bars can also be incorporated into industrial processing systems handling compatible:

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

Suitability depends on the characteristics of the product stream, contaminants and operating environment.

Installation Considerations

Before installation:

• Confirm the 20mm diameter x 240mm length suits the equipment
• Verify compatibility with the M8 thread
• Confirm the one-threaded-end / one-sealed-end configuration suits the mounting arrangement
• Position the separator where material passes close to its magnetic surface
• Consider product depth and flow rate
• Allow appropriate access for cleaning
• Secure the separator appropriately
• Establish a regular inspection and cleaning schedule

Where the separator bar projects from a single mounting point, the complete installation should adequately support the assembly and account for forces generated during operation and cleaning.

Cleaning and Maintenance

Captured ferrous contamination should be removed periodically from the magnetic tube.

Cleaning frequency depends on:

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

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

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

Please Note

This product is a Separator Bar Tube Magnet measuring 20mm in diameter x 240mm long, featuring an M8 threaded connection at one end and a sealed opposite end.

No specific Gauss rating, pull force, magnetic material or grade, tube material, stainless steel grade, surface finish, M8 thread depth, 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, installation geometry, proximity to the magnetic surface and cleaning frequency.

For food, pharmaceutical or other regulated applications, verify the construction materials, surface finish, fabrication, cleaning procedures and 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.
