Magnetic bar

Points:

1. The standard cylindrical magnetic bar is 25mm(1 inch) in diameter, and the length can be machined according to customer requirements, up to 2500mm.Square or other magnetic rods of different shapes and sizes are also available.

2.Use 304 or 316L seamless stainless steel tube, the surface can be polished to meet the special requirements of food, pharmaceutical and other fields.

3. Standard operating temperature ≤80℃, under special requirements, the maximum operating temperature can reach 350℃.

4.Diversified design at both ends ---- tips, threaded holes, studs, etc.

5. Using ferrite permanent magnet and rare earth permanent magnet of different grades, magnetic rods with different surface magnets can be produced to meet the needs of customers. The maximum surface magnetism of MAGNETIC rods with D25mm can reach 13000GS.

Magnetic bar is a simple and practical magnetic filter with a wide range of applications. It is used to adsorb ferromagnetic particles around it to remove iron and protect subsequent equipment.You can follow the following steps to design and select a suitable magnetic bar:

Calculate magnetic field strength

The precise magnetic field strength is calculated by finite element method, but the complicated and tedious steps are daunting. It can be simply selected for the following applications and corresponding table magnetism:

Dry powder	7000-8000 gauss
paste	9000-10000 gauss
Nanoparticles,	> 12000 Gauss

Determine the size of the powerful magnetic bar

1. Diameter: The magnetic bar adopts standard series of stainless steel pipe, the outer diameter and the maximum surface magnetic field can be reached as shown in the table:

2.Length: Length customization.

3. Working temperature: ferrite magnet, Ndfeb magnet and high temperature resistant samarium cobalt magnet are available.

Mounting method of magnetic bar

In addition to the iron bar at both ends of the plug in various forms, commonly used are:

1637717095(8)

Threaded hole
1637717124(9)

Screw head

1637717149(10)

Flat head

Mounting method of magnetic bar

SS304	Widely used in most environments
SS316/316L	More corrosion resistant, used in the pharmaceutical and food industries

The magnetic bar iron remover is composed of high density magnetic field magnetic circuit composed of strong magnet and magnetic guide sheet. It is sealed in stainless steel tube by argon arc welding. After strict polishing process, the surface is smooth without leakage, waterproof and antifouling.It can absorb ferromagnetic materials in mud and powder, and nano-sized particles can be absorbed when 12000 Gauss is above.

Working temperature	80-350°C
Surface magnetic field	Up to 13,000 gauss
Outer diameter	Up to 100 mm
The length of the	The length of the custom
The installation	All kinds of plug
Stainless steel	SS304 /316/316L

Before inquiry, you may want to know how to avoid 4 pits of inferior magnetic bar. The magnetic bar goes through 4 polishing processes, defect point inspection, and the surface finish can reach Ra0.6.Especially suitable for medical and food applications with high surface quality requirements, see our polishing process video.

Application areas:

Magnetic bars are mainly used in magnetic separators composed of magnetic racks, which can effectively absorb iron impurities and metal particles in loose or flowing raw materials.
