Separator Bar Tube Magnet – 25mm x 600mm | M8 Thread

The Separator Bar Tube Magnet – 25mm x 600mm | M8 Thread is a long-format 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 600mm in length, this magnetic tube provides extensive coverage across wider product streams and processing equipment.

Featuring an M8 threaded mounting point, the separator bar can be installed individually or incorporated into compatible magnetic grids, grate magnets and custom magnetic separation systems. Its extended 600mm length makes it particularly suitable for wider hoppers, chutes, ducts and processing lines where greater magnetic coverage is required.

As material passes around the magnetic tube, susceptible iron and steel particles are attracted towards the magnetic surface and retained for removal. This helps reduce unwanted ferrous contamination, improve material purity and protect downstream machinery 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, generates a magnetic field around its outer surface.

When compatible material flows around the tube, magnetically susceptible iron and steel contamination is attracted away from the product stream and retained on the magnetic surface.

The captured ferrous particles remain attached to the separator bar until removed during routine cleaning. Correct positioning within the material flow helps maximise exposure to the magnetic field and improve contamination capture.

Why Choose a 600mm Separator Bar?

The 600mm length provides broad coverage for larger processing areas where shorter magnetic tubes may not extend sufficiently across the product stream.

This makes the separator bar particularly suitable for installation in compatible:

• Wide hoppers
• Processing chutes
• Bulk material streams
• Magnetic grate frames
• Magnetic grids
• Custom separation equipment

Multiple 600mm magnetic separator bars can also be positioned parallel to one another to create a larger magnetic grid. This arrangement increases magnetic coverage and reduces pathways through which material can pass without approaching a magnetic surface.

M8 Thread for Equipment Integration

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

Depending on the equipment design, the tube magnet may be used individually or incorporated into a larger grate magnet, magnetic grid or custom filtration system.

Always confirm the M8 thread, 25mm diameter and 600mm length are compatible with the intended mounting system before installation.

Industrial Magnetic Separation Applications

The 25mm x 600mm M8 separator bar is suitable for manufacturers, processors, engineers and equipment builders requiring magnetic contamination control across a relatively wide processing area.

Correctly positioned separator bars can help:

• Capture unwanted iron and steel contamination
• Improve material and finished-product purity
• Protect downstream machinery from ferrous fragments
• Reduce the risk of equipment damage
• Support contamination-control procedures
• Provide magnetic separation without electrical power

The effectiveness of the system will depend heavily on the location and arrangement of the magnetic bars within the material flow.

Getting the Best Separation Performance

Magnetic attraction decreases rapidly with distance, so material should pass as close as practical to the magnetic surface while maintaining appropriate product flow.

Separation performance can be influenced by:

• Contaminant size and shape
• Magnetic properties of the contaminant
• Material depth
• Product flow rate
• Distance from the magnetic surface
• Installation geometry
• Quantity of contamination already collected

For wider product streams, multiple separator bars may provide more effective coverage than a single magnetic tube.

Cleaning and Maintenance

Captured ferrous material should be removed from the separator bar regularly to maintain effective magnetic performance.

Cleaning frequency will depend on the amount of material processed and the level of contamination present. Excessive accumulation can reduce the available collection surface and potentially affect the separator's ability to capture additional particles.

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

Please Note

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

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

Where a Gauss rating is required for a specific application, refer to the product's confirmed technical specifications rather than assuming magnetic field strength from the dimensions alone.

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