Separator Bar Tube Magnet – 22mm x 130mm with Sealed Ends

The Separator Bar Tube Magnet – 22mm x 130mm with Sealed Ends is a compact industrial magnetic separation tube designed to attract and capture magnetically susceptible ferrous contamination from compatible powders, granules and other free-flowing materials. Measuring 22mm in diameter x 130mm in length, this permanent magnetic separator features sealed ends, making it suitable 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 works by attracting iron and steel particles that pass sufficiently close to its magnetic surface. Captured ferrous contamination is retained on the tube for removal during scheduled cleaning and maintenance.

Its compact 22mm diameter and 130mm length make this separator bar particularly useful for smaller processing equipment, confined installations and custom magnetic separation systems across food and ingredient processing, pharmaceutical manufacturing, plastics, chemical processing, manufacturing and bulk material handling.

22mm x 130mm Compact Separator Bar

Measuring 22mm in diameter x 130mm long, this magnetic separator bar provides a compact cylindrical format for applications where installation space is limited.

The relatively short 130mm length can make it useful for:

• Smaller hoppers
• Compact chutes
• Narrow material-flow paths
• Custom processing equipment
• Magnetic filter assemblies
• OEM magnetic separation systems
• Space-restricted installations

The required separator size should be selected according to the dimensions of the processing equipment and the characteristics of the material stream.

Sealed-End Construction

This separator bar is specified with sealed ends, providing an enclosed tube configuration.

Unlike separator bars supplied with an exposed threaded mounting connection, no external mounting thread has been specified for this model.

The sealed-end design may be useful for custom installations where the magnetic tube is incorporated into a separate holder, housing or supporting structure.

The exact end geometry, mounting method and construction details have not been supplied and should be confirmed where these characteristics are critical to the application.

How Does a Separator Bar Tube Magnet Work?

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

During operation:

1. Powder, granules or another compatible material passes around the magnetic tube.
2. Magnetically susceptible iron and steel contamination enters the magnetic field.
3. Ferrous particles are attracted towards the separator surface.
4. Captured contamination remains on the magnetic tube.
5. Accumulated ferrous material is periodically removed during cleaning.

The separator can operate continuously without requiring electrical power to generate magnetic attraction.

Ferrous Contamination Capture

This magnetic separator tube is designed primarily to capture 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 processing or handling

Removing these contaminants can support product-quality procedures and help reduce the risk of ferrous material reaching downstream equipment.

Magnetic Attraction Decreases with Distance

The effectiveness of a separator bar depends heavily on how close the contamination passes to the magnetic surface.

Magnetic attraction decreases rapidly with distance.

For effective separation, the processing system should therefore be designed so that material passes sufficiently close to the magnetic tube.

Performance can be influenced by:

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

The compact dimensions of this tube can make it useful for positioning magnetic separation close to the material stream in appropriately designed equipment.

Magnetic Separation Performance

Overall separation efficiency depends on more than the physical dimensions of the magnetic tube.

Important factors include:

• Magnetic field strength
• Contaminant magnetic properties
• Contaminant size and shape
• Material characteristics
• Product depth
• Flow rate
• Distance from the tube
• Separator arrangement
• Installation geometry
• Cleaning frequency

No specific Gauss rating has been supplied for this product, so magnetic field strength should not be inferred from the 22mm diameter or separator-bar construction.

Permanent Magnetic Operation

This separator bar uses a permanent magnetic system, allowing it to provide continuous magnetic attraction without an electrical power supply.

There is no requirement for:

• Electrical wiring
• Batteries
• Charging
• Powered magnetic coils
• Continuous electricity

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

Ferrous vs Non-Ferrous Contamination

Magnetic separator tubes are primarily designed to attract 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 metal contamination needs to be detected or removed, additional separation or detection technologies may be required.

Food and Ingredient Processing

Separator bars can be incorporated into compatible food and ingredient-processing systems to assist with the removal of unwanted ferrous contamination.

Potential applications may include:

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

For food-contact applications, verify that the complete separator assembly satisfies the relevant material, surface-finish, fabrication, cleaning, hygiene and HACCP requirements.

A specific stainless steel grade, surface finish or food-contact certification has not been supplied for this product and should not be assumed.

Plastics, Pharmaceutical and Industrial Applications

This compact separator bar may also be incorporated into compatible systems processing:

• Plastic pellets
• Polymer granules
• Pharmaceutical powders
• Chemical powders
• Industrial feedstocks
• Manufacturing raw materials
• Other compatible dry products

The suitability of the magnetic separator should be assessed against the material, operating conditions and contamination-control requirements of the complete process.

Installation Considerations

Before installation:

• Confirm the 22mm diameter x 130mm length suits the equipment
• Confirm the sealed-end configuration is compatible with the intended mounting method
• Position the magnetic tube close to the material-flow path
• Minimise opportunities for product to bypass the magnetic field
• Consider product depth and flow rate
• Allow appropriate access for inspection and cleaning
• Secure the separator appropriately for the application
• Establish a regular cleaning schedule

Because no threaded mounting connection has been specified, the appropriate method for securing the sealed separator bar should be determined from the actual product construction and equipment design.

Cleaning and Maintenance

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

Cleaning frequency depends on:

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

Excessive accumulation can reduce the available magnetic collection surface and may affect subsequent contamination capture.

Because the magnetic field remains permanently active, appropriate machinery isolation, handling procedures and personal protective equipment should be used during cleaning.

Please Note

This product is a Separator Bar Tube Magnet measuring 22mm in diameter x 130mm long with sealed ends.

No specific Gauss rating, pull force, magnetic material or grade, tube material, stainless steel grade, surface finish, mounting configuration, 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 processing applications, confirm 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.
