Separator Bar Tube Magnet – 25mm x 450mm | M8 Thread

The Separator Bar Tube Magnet – 25mm x 450mm | M8 Thread is an industrial magnetic separator bar designed to capture and remove unwanted ferrous metal contamination from powders, granules and other compatible free-flowing materials. Measuring 25mm in diameter and 450mm in length, this magnetic tube provides broad separation coverage for manufacturing, processing and material handling applications.

Featuring an M8 threaded mounting point, the separator bar can be incorporated into compatible magnetic grate frames, magnetic grids and custom separation systems. Its 450mm length makes it particularly useful for medium-to-large hoppers, chutes, ducts and processing lines where extended magnetic coverage is required.

When installed directly within a product flow, magnetically susceptible iron and steel particles are attracted towards the magnetic tube and retained on its surface. This helps reduce unwanted ferrous contamination while also helping protect downstream machinery and processing equipment from potentially damaging metal fragments.

How Does a Magnetic Separator Bar Work?

A separator bar, also commonly called a tube magnet, magnetic filter bar, magnetic separator rod or magnetic tube, generates a concentrated magnetic field around its external surface.

As material passes around the tube, magnetically susceptible ferrous particles are attracted away from the product stream and towards the magnetic surface. The captured iron and steel contamination remains attached to the bar until removed during routine cleaning.

Installing separator bars directly within the material flow helps maximise exposure to the magnetic field and improves the likelihood of ferrous contaminants passing close enough to the magnetic surface to be captured.

Why Choose a 450mm Separator Bar?

The 450mm length provides substantial coverage across wider processing areas while remaining practical for integration into many industrial systems.

This makes the tube magnet suitable for installation across compatible hoppers, chutes, ducts and processing equipment. It can be used individually or combined with additional 450mm separator bars to create a larger magnetic grate or grid.

Where multiple bars are installed parallel to one another, they can provide broader magnetic coverage across the product stream and reduce the available pathways through which ferrous contaminants can pass without approaching a magnetic surface.

M8 Thread for Equipment Integration

The integrated M8 thread provides a practical connection point for mounting the separator bar into compatible industrial equipment.

Depending on the separator design, the bar can be incorporated into:

• Magnetic grids
• Grate magnet frames
• Hopper magnet systems
• Custom separator assemblies
• Purpose-built processing equipment

Always confirm the M8 thread, 25mm diameter and 450mm length are compatible with your existing equipment before installation.

Industrial Magnetic Separation Applications

The 25mm x 450mm M8 separator bar is suitable for manufacturers, processors, engineers and equipment builders requiring reliable ferrous contamination control across a relatively wide material stream.

Depending on the application, tube magnets can be positioned inside hoppers, chutes, ducts, product streams and magnetic grate assemblies. Correct positioning is important, as magnetic attraction decreases rapidly as the distance between the contaminant and magnetic surface increases.

Effective magnetic separation can help:

• Reduce unwanted iron and steel contamination
• Protect downstream machinery from ferrous fragments
• Improve material purity
• Reduce the risk of equipment damage
• Support product quality and contamination-control procedures

Cleaning and Maintenance

Captured ferrous material should be removed from the magnetic tube regularly to maintain effective separation performance. Cleaning frequency will depend on the amount of material processed and the level of contamination present.

Before cleaning or servicing, isolate the separator from moving machinery and product flow according to applicable workplace procedures.

Regular inspection of the magnetic tube, M8 mounting point and surrounding separator assembly is recommended to ensure components remain secure and in suitable operating condition.

Please Note

Actual magnetic separation performance depends on several factors, including the size, shape and magnetic properties of the contamination, product characteristics, material flow rate, installation geometry and distance from the magnetic surface.

For effective separation, material should pass as close as practical to the magnetic tube while maintaining appropriate product flow.

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

Strong magnetic fields may affect pacemakers, medical implants, magnetic storage media and sensitive electronic equipment. Appropriate workplace procedures should be followed when installing, cleaning and servicing magnetic separation equipment.
