Magnetic Grate

Magnetic Grate

separation line-918x2



Magnetic Grate  can be  used in chute or made into drawer magnets together with stainless steel housing. 304 stainless steel construction and 316L also can be obtained.

We produce various grate magnets, equiped our magnetic tube, surface gauss can reach over 12000Gs, they are widely used in food, chemical and Pharmaceutical industries.

Avaliable materials are stainless steel 304, 316 and 316L.

We support free designs and drawings according to your requirements.

3 Steps To Get Your Individual Grate Magnet

Grate magnets are completely customized. Your individual requirements need an individual solution.

Step 1- Design

How to Calculate a Magnetic Field of a Magnetic Bar?

Finite element models can calculate the strength of magnetic field. It is quite difficult, but practical we use below value:

Dry Powder 7000-8000 Gauss
Wet Slurry 9000-10000 Gauss
Nanometer Particles over 12000 Gauss


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 diameter, bottom diameter and the height. We will help you to finish the next steps and place a real magnetic grid into your hand.

Step 2- Payment & Production

Payment: We accept Paypal and T/T

Production: We will start the production when both of us confirm the design.

We own a magnets factory; therefore, we have various types of magnets in stock allowing us to finish  production within 3 days.  This timeframe is for general orders and we definitely offer competitive prices.

Step 3- Delivery

You give us your address, we ship it and you wait for your delivery. We will handle everything. Air and sea transportaiton is avaliable.



These are widely used magnetic grids, we shorten the lead time to 3 days through optmizing stock and technology.

This huge grid has a diameter of 2840mm and 18pcs tubes. All seams are fully welded, a rounded R1 and well polished. They are used in high end food processing factory.

This fast cleaning grid is composed of two parts: a high gradient magnetic grid and an SS316 cover grid.  We pull off the magnetic grid when we clean it. The ferrous contaminant, which attaches on the surface of cover grid, will drop off as the disappearance of magnetic force. It is easy to clean the whole set in seconds. Similarly, an easy cleaning grate can equip an automatic magnetic separation equipment.

Double or multilevel grid, in which all seams are full welded. No dead angle, easy cleaning. First choice for the food processing industry.
