1. Magnetic filter bar,Magnetic Rods,Magnetic Filter tube(Magnetic Separator) is extremely efficient at removing fine iron contamination from free flowing products such as sugar, grain, tea, flour, Plastic, liquid, granulate and any other type of powder with a low moisture content. As a result, your equipment and facilities will be safe and sound, and your products will be safe for consumption. This item can be supplied with any shape frame or studded end for easy of installation.

2. Magnetic filter bar are particularly useful for those engineers who wish to build their own separator units or have severe room restrictions and are not able to accommodate a conventional unit. All product contact parts are manufactured using stainless steel.

3. The magnetic filter bar with special welding at the both ends without leak forever. Welding energy concentrate on welding line and do not hurt the magnet, maximal protect magnetic filed. The available magnetic area can be expanded to the limited of rod surface and without add any extra magnet. Once welded the rods are finish machined and highly polished.

How to Calculate Magnetic Field?
Finite element models can calculate the strength of a magnetic field. It is quite difficult, but practical we use the value below:

Dry Powder7000-8000 Gauss
Wet Slurry9000-10000 Gauss
Nanometer Particlesover 12000 Gauss

How to Design the Size of Magnetic Tube?

1. Diameter: Diameters are in a series. The relationship between the diameter and max. gauss value is as below:





* recommended diameter is Ø25mm(1″)

2. Length: Custom and made to any length

How to Design the Installation?

Installation Endplug: Taped holes, threaded studs or plain ends based on your requirements

How to make sure the material of stainless steel tube is correct?

SS304Widley used in most applications

SS316/316LMore corrosion resistance, and are used in food or chemical industries

About Magnetic Grid/Grate/Grill


Magnetic Grid(Grate or Grill) are used for separation of iron particles mixed with dry, granular or free flowing material. Magnetic Grid(Grate or Grill) are made by using stainless steel frames (Round, Square or Rectangular) with Magnetic Rods inside the frame.

These Magnetic Grid(Grate or Grill) are made up of Magnetic Elements which are fitted inside a required size frame. The Magnetic Elements are made up of High Intensity Rare Earth NdFeB Magnets. All the components are made up of Stainless Steel 304/316 material. The overall construction of the Magnetic Grill can also be made as per the customer specification and sizes

The Magnetic Grid(Grate or Grill) are efficiently utilized if contamination is within 1% to 1.5% by weight. For higher levels of contamination Drawer Grills or Multi Drawer Grills should be used.

High Intensity Magnetic Grid(Grate or Grill) having Gauss value of approximately 12,000 Gauss are employed at locations where separation of contamination particles as small as 1 microns is required. These grills have been designed to attract super fine particles from the carrier material.

Magnetic grate optional features:

1. The shell material: SS304, SS316,SS316L;
2. The magnetic strength grade: 2000Gs, 3000Gs, 6000Gs, 8000Gs,10000Gs, 12000Gs;
3. Working temperature grade <: 80, 100, 120, 150, 180, 200, 250, 300 degree Celsius;
4. Various designs available: easy clean type, one layer, multilayer;
5. Sizes and Shape: any sizes and any shapes, such as square, rectangle, round, oval, triangle, rhombus or irregular polygon;
6. Also takes customers' designs.

Field of applications for the magnetic filter grate/grid:

Pharmaceutical industry
Chemical industry
Food industry
Plastic industry

How to Make Sure the Size of a Magnetic Grid is Correct?

Please measure the hopper’s size if you do not have the magnetic grate’s drawing. For example, 3 pieces of data are needed: top diameterbottom diameter and the height. We will help you to finish the next steps and place a real magnetic grid into your hand.
