Separator Bar Tube Magnet – 25mm x 165mm | M8 Thread

The Separator Bar Tube Magnet – 25mm x 165mm | M8 Thread is a compact 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 165mm in length, this tube magnet provides effective magnetic separation in applications where installation space is limited.

Featuring an M8 threaded mounting point, the magnetic bar can be installed individually or incorporated into compatible magnetic grids, grate magnets, hoppers and custom magnetic separation systems. Its compact 165mm length makes it particularly suitable for smaller processing equipment and purpose-built separator assemblies.

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 while also helping 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.

When compatible material flows around the tube, magnetically susceptible iron and steel contaminants are attracted away from the product stream and retained against the magnetic surface.

Captured ferrous material remains attached to the tube until removed during routine cleaning. Correct positioning of the separator within the product stream is important for effective contamination capture.

Compact 165mm Design

The 165mm length makes this separator bar particularly useful for smaller processing systems where a longer magnetic tube may not fit.

Potential installation locations include:

• Small hoppers
• Chutes
• Ducts
• Product streams
• Processing equipment
• Magnetic filtration systems
• Custom separator assemblies

For applications requiring broader magnetic coverage, multiple separator bars can be positioned together to form a magnetic grate or grid system.

M8 Thread for Equipment Integration

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

Depending on the system design, the tube magnet can be used individually or combined with other separator bars to create a larger magnetic separation assembly.

Always confirm the M8 thread, 25mm diameter and 165mm length are compatible with the intended equipment and mounting configuration before installation.

Industrial Magnetic Separation Applications

The 25mm x 165mm M8 separator bar is suitable for manufacturers, processors, engineers and equipment builders requiring a compact magnetic contamination-control solution.

Correctly positioned magnetic separator bars can help:

• Capture unwanted iron and steel contamination
• Reduce ferrous particles in processed materials
• Improve material and finished-product purity
• Protect downstream machinery from metal fragments
• Reduce the risk of equipment damage
• Support contamination-control and quality-assurance procedures

Because the separator operates using a permanent magnetic field, no electrical power is required for normal magnetic separation.

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 vary depending on:

• Contaminant size and shape
• Magnetic properties of the contaminant
• Product characteristics
• Material depth
• Flow rate
• Distance from the magnetic surface
• Installation geometry

For larger product streams, multiple separator bars may provide better magnetic coverage than a single tube.

Cleaning and Maintenance

Captured ferrous contamination 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 separator efficiency.

Before cleaning or servicing, isolate the magnetic 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 specific Gauss rating is required, refer to the product's confirmed technical specifications rather than estimating magnetic field strength from its dimensions.

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.
