Separator Bar Tube Magnet – 25mm x 800mm | M8 Thread

The Separator Bar Tube Magnet – 25mm x 800mm | 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 800mm in length, this extended magnetic tube provides broad coverage across larger 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 substantial 800mm length makes it particularly suitable for wide hoppers, chutes, ducts and bulk-processing systems where shorter magnetic bars may not provide sufficient coverage.

As material passes around the magnetic tube, magnetically susceptible iron and steel particles are attracted to the magnetic surface and retained for removal. This helps reduce 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 external surface.

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

Captured ferrous particles remain attached to the separator bar until removed during routine cleaning. Correct positioning within the product flow is important to ensure material passes sufficiently close to the magnetic surface.

Extended 800mm Magnetic Coverage

The 800mm length makes this separator bar particularly suitable for larger processing equipment and wide product streams.

Potential installation locations include:

• Wide hoppers
• Processing chutes
• Bulk material streams
• Large ducts
• Magnetic grate frames
• Magnetic grids
• Custom processing equipment

The extended length can provide magnetic coverage across wider areas without requiring multiple shorter bars positioned end-to-end.

Multiple 800mm separator bars can also be arranged parallel to one another to create a large magnetic grid or grate system.

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 system design, the tube magnet may be used individually or incorporated into:

• Magnetic grids
• Grate magnet frames
• Hopper separators
• Chute separators
• Magnetic filtration systems
• Custom processing assemblies

Always confirm that the M8 thread, 25mm diameter and 800mm length are compatible with the intended equipment and mounting configuration before installation.

Industrial Magnetic Separation Applications

The 25mm x 800mm M8 separator bar is particularly suited to manufacturers, processors and equipment builders requiring magnetic contamination control across a wide processing area.

Correctly positioned separator bars can help:

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

For particularly large product streams, several separator bars can be incorporated into a purpose-built magnetic grid to increase magnetic coverage.

Getting the Best Separation Performance

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

Separation efficiency can be affected by:

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

The separator should be positioned so that product cannot easily bypass the magnetic collection area.

Cleaning and Maintenance

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

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

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

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

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