Separator Bar Tube Magnet – 25mm x 350mm | M6 Thread

The Separator Bar Tube Magnet – 25mm x 350mm | M6 Thread is an industrial magnetic separator bar designed to capture magnetically susceptible iron and steel contamination from powders, granules and other compatible free-flowing materials. Measuring 25mm in diameter x 350mm long and featuring an M6 threaded mounting connection, this tube magnet can be installed individually or incorporated into custom magnetic grates and separation systems.

Also known as a magnetic separator rod, magnetic tube or magnetic filter bar, this permanent magnetic separator provides a simple, reusable method of removing ferrous contamination from product flows without requiring electrical power. Its 350mm length provides useful magnetic coverage for processing equipment, hoppers, chutes and custom separator assemblies.

Suitable for applications across food and ingredient processing, pharmaceutical manufacturing, plastics, chemicals, recycling and general manufacturing, this 25mm magnetic separator bar can help protect downstream equipment and improve ferrous contamination control.

How Does a Magnetic Separator Bar Work?

A magnetic separator bar generates a permanent magnetic field around its outer tube. When compatible material passes sufficiently close to the magnetic surface, magnetically susceptible iron and steel particles are attracted towards the tube and retained.

Captured contamination remains on the magnetic surface until the separator bar is removed or cleaned.

Depending on the application, separator bars can help capture contaminants such as:

• Fine iron particles
• Steel fragments
• Ferrous swarf
• Rust particles
• Small screws and fasteners
• Other magnetically susceptible contamination

For effective separation, the system should be configured so the product flow passes close to the magnetic surface.

350mm Length for Magnetic Separation Systems

The 350mm tube length provides useful magnetic coverage for medium-sized processing equipment and custom separator assemblies.

The bar may be installed individually in a suitable product flow or combined with multiple separator tubes to create a magnetic grate covering a larger processing area.

Multiple-bar configurations can be arranged to encourage material to flow around and between the magnetic tubes, increasing the opportunity for ferrous contamination to enter the effective magnetic field.

M6 Thread for Equipment Integration

The M6 threaded connection provides a convenient method for securing the separator bar within compatible processing equipment, support frames and custom magnetic grate assemblies.

Potential installations include:

• Hoppers
• Chutes
• Product inlets
• Magnetic grates
• Separator frames
• Processing lines
• Custom fabricated equipment

Before installation, confirm the mating thread and mounting hardware are compatible with the separator bar.

Magnetic Grate and Custom Separator Applications

Multiple 25mm diameter separator bars can be incorporated into a suitable frame to create a custom grate magnet.

A grate configuration allows several magnetic tubes to be positioned across the material flow. As the processed material travels between the tubes, ferrous contamination can be attracted and retained on their surfaces.

Effective grate design should consider:

• Number of magnetic bars
• Tube spacing
• Product flow rate
• Material characteristics
• Contaminant size
• Installation geometry
• Cleaning access
• Distance between the product and magnetic surfaces

Magnetic attraction decreases rapidly with distance, so positioning and spacing can significantly influence separation performance.

Industrial Ferrous Contamination Control

Magnetic separator bars are widely used in processing systems where unwanted ferrous material may enter raw ingredients, powders, granules or manufactured products.

Depending on the installation, a separator bar can help protect downstream equipment from ferrous debris and support contamination-control procedures.

Potential industries include:

• Food production
• Ingredient processing
• Pharmaceutical manufacturing
• Plastics and polymers
• Chemical manufacturing
• Recycling
• Powder processing
• General manufacturing

The separator should be positioned at an appropriate stage of the production process according to the characteristics of the material and equipment.

Cleaning and Maintenance

Captured ferrous material should be removed regularly to maintain effective magnetic separation.

The required cleaning frequency will depend on the amount of contamination, product throughput and operating environment.

During maintenance:

• Follow applicable equipment isolation procedures
• Remove accumulated ferrous contamination carefully
• Avoid damaging the separator tube surface
• Inspect the tube for wear or physical damage
• Check mounting points and threaded connections
• Ensure the bar is correctly repositioned before restarting equipment

Regular inspection is particularly important where the separator forms part of a formal contamination-control process.

Separation Performance

Actual magnetic separation performance depends on factors including:

• Contaminant size and shape
• Magnetic properties of the contaminant
• Material flow rate
• Product characteristics
• Distance from the magnetic surface
• Tube positioning
• Installation geometry
• Quantity of accumulated contamination

A specific Gauss rating has not been provided for this separator bar, so magnetic field strength should not be inferred from the product dimensions alone.

Please Note

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

Where the separator is intended for food, pharmaceutical or other regulated processing applications, confirm that the complete product specification, materials, installation and cleaning procedures meet the relevant requirements for the application.

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