Separator Bar Tube Magnet – 25mm x 700mm | M8 Thread

The Separator Bar Tube Magnet – 25mm x 700mm | M8 Thread is a long-format 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 700mm in length, this magnetic tube provides extensive separation coverage for industrial processing, manufacturing and material handling applications.

The integrated M8 threaded mounting point allows the separator bar to be installed into compatible magnetic grate frames, magnetic grids and custom separation systems. Its extended 700mm length makes it particularly suitable for wider hoppers, chutes, ducts and processing equipment where greater magnetic coverage is required.

When positioned within a product flow, magnetically susceptible iron and steel particles are attracted towards the surface of the separator tube and retained there. This helps remove unwanted ferrous contamination from the material stream while also helping protect downstream processing equipment from potentially damaging metal fragments.

How Does a Magnetic Separator Bar Work?

A separator bar, also known as a tube magnet, magnetic filter bar, magnetic separator rod or magnetic tube, creates a strong magnetic field around its outer surface.

As product passes around the tube, magnetically susceptible ferrous contamination such as iron and steel particles is attracted towards the magnetic surface. The contamination remains attached to the bar until it is removed during routine cleaning.

Positioning separator bars directly within the product flow helps maximise the likelihood that contaminants pass close enough to the magnetic surface to be captured.

Why Choose a 700mm Separator Bar?

The 700mm length provides significantly greater magnetic coverage than shorter separator bars, making this model particularly useful for wider industrial equipment and larger material streams.

Its long profile can span suitable hoppers, chutes and processing areas or be combined with additional separator bars to create a large magnetic grate or grid system.

For applications involving broad product flows, multiple 700mm tube magnets can be positioned parallel to one another to increase magnetic coverage and minimise gaps through which ferrous contamination could pass.

M8 Thread for Equipment Integration

The integrated M8 thread provides a practical mounting point for installation into compatible industrial equipment and custom magnetic separator assemblies.

Depending on the system design, the separator bar may be installed individually or combined with multiple magnetic tubes to form a grate magnet, magnetic grid or purpose-built separator system.

Always confirm the required thread, mounting arrangement, dimensions and equipment compatibility before installation.

Industrial Magnetic Separation Applications

This 25mm x 700mm M8 separator bar is suitable for manufacturers, processors, engineers and equipment builders requiring extensive magnetic coverage across larger processing areas.

Depending on the application, separator bars can be positioned inside hoppers, chutes, ducts, product streams and magnetic grate assemblies. As material flows around the tubes, ferrous contamination is attracted away from the product and retained on the magnetic surface.

This type of magnetic separation can help:

• Reduce unwanted ferrous contamination in processed materials
• Protect downstream machinery from metal fragments
• Reduce the risk of equipment damage
• Improve material purity and product quality
• Support preventative maintenance and contamination-control procedures

Cleaning and Maintenance

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

Before cleaning or servicing, isolate the magnetic separator from product flow and moving machinery according to the site's safety procedures.

Regular inspection is also recommended to check the condition of the tube, mounting points and surrounding separator assembly.

Please Note

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

Magnetic attraction decreases rapidly with distance. For effective separation, material should pass as close as practical to the magnetic tube while maintaining appropriate product flow.

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

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