Product Description

Magnetic Grill, Magnetic Grate, Grate Magnets, Hopper Magnet description:

The hopper magnet is mainly used to remove iron impurities in hoppers, feeding troughs, and floor spaces, and can effectively remove free-flowing powders and iron impurities in small particles. The grate magnet is equipped with a beautiful appearance and reasonable distribution of magnetic bars, which can provide a high-strength magnetic field to attract the iron powder, iron filings, and other small pieces of magnetic metal in the flowing material.

The stainless steel seamless pipe and the outer frame are welded by skilled workers to form a strong whole. It can be installed on the production line, or simply placed in the hopper or material box, and can be easily taken out and cleaned. The grate magnet is made of materials, and the surface is corrosion-resistant, which can reach the cleanliness level of food and even medicine. GME's hopper magnet usually uses 25mm diameter magnetic rods, arranged in parallel at a center spacing of 40mm.

Magnetic Grill, Magnetic Grate, Grate Magnets, Hopper Magnet style:

In practical applications, the commonly used magnetic grid forms are:

1. Drawer-type grille iron remover, the magnetic grille is fixed in the stainless steel frame to achieve the purpose of a convenient connection with the production pipeline and convenient cleaning and operation.

2. Fluid pipeline type iron separator, the magnetic grid is placed in a three-way stainless steel barrel container, and it is convenient to transport liquid or powder to the pipeline through the flange, quick connection, or pipe thread of the stainless steel barrel container. The connection is not only easy to clean and operate, but also does not affect the flow and flow rate of the pipeline.

3. Rotary grille iron remover, through the decelerating motor, to drive the magnetic grille to rotate, thus effectively avoiding the bridging and blockage of some powder materials with poor fluidity when they flow through the ordinary magnetic grille or drawer type grille separator In the case of the pipeline, the speed can be customized according to the actual operating conditions, but the speed is not too fast.

4. The easy-to-clean magnetic grid is generally used for square magnetic grids. A stainless steel sleeve is added to the surface of the round magnetic rod. When cleaning, the magnetic rod of the magnetic grid is pulled out of the stainless steel sleeve. , The magnetic impurities adsorbed on the surface of the magnetic grid will easily leave the surface of the magnetic rod.

Working principle of Magnetic Grill, Magnetic Grate, Grate Magnets, Hopper Magnet:

The magnetic filter hopper magnet is made of high-quality stainless steel tubes and high-B rare earth alloy neodymium iron boron and is made by a special manufacturing method.

And the combination is fixed on the fixed frame to form a hopper magnet. When the iron-containing material passes, it is attracted by the magnetic rod, and the iron-containing material is firmly adsorbed on the tube wall to ensure the integrity of the equipment and the safety of the product.

Magnetic Grill, Magnetic Grate, Grate Magnets, Hopper Magnet Easy Clean: 

The hopper magnet is made of multiple magnetic rods fixed by steel plates. Many customers feedbacks that the conventional strong hopper magnet is not convenient to clean, for this we introduced the easy-removable hopper magnet. It greatly reduces the cleaning time of the magnetic material on the rods and can improve the efficiency of the work well.

 

The easy to clean magnetic grate is a combination of stainless steel empty frame + a complete unconventional magnetic shelf. GME's magnetic grates are cut out by laser cutting technology and shaped by manual skilled welding, with small dimensional tolerance and high quality.

 

How to choose surface Gauss:

If the metal you want to attract is Screw, thread, or nut, 2500-2800GS.

If the metal is an iron powder, 10,000GS

 

For 2500-2800GS, it is often by not welding type as below:

For 10,000GS, it is often by welding type as below:

How to choose a Magnetic Grill, Magnetic Grate, Grate Magnets, Hopper Magnet:

Hopper Magnets are made up of a combination of multiple magnetic rods, so the main thing to judge a Grate Magnet is the quality of the rods. Of course, in addition to the magnetic rods, it is also necessary to look at the combination of the magnetic holder sequence design.

The magnetic rods are made of strong magnets and magnetic guide plates arranged in a prescribed order, but because the rods are sealed, it is impossible to disassemble them to see the inside condition. So how do we determine if the magnet and magnetic guide of this rod is evenly ordered and if the magnetic induction line is even? At this time, we can look at the magnetic lines, you can sprinkle a little iron powder, the distribution of iron powder is the distribution of magnetic induction lines, so as to judge whether the order of the magnets and iron sheet of this magnetic rod is reasonable.

In addition to the magnetic induction wire, we also need to see if the exterior of the magnet is smooth and free of burrs, sealed in place. The magnet material inside should not be exposed on the outside to avoid direct contact with the material, which may pollute the material and the environment.

In order to have a good experience when you buy a Grate Magnet, please tell us your usage situation, because the application environment, the design of the magnetic rack, and the magnetic bar have different requirements.

How to select and identify 304 and 316 stainless steel

1.   Whether it contains MO: Stainless steel screw 316 contains more MO than 304, and its corrosion resistance and acid and alkali resistance are better than 304;

2.   Nickel content is different: ≥10%: 316 material, between 8% and 10% is 304 stainless steel;

3.   The energized potion identification experiment: based on chemical analysis, with the aid of batteries to make the material surface oxidation reaction, through the appropriate control technology to make the measured elements and reagents to generate colored chromium compounds. (Which N8 test 304 stainless steel, energized point solution after the potion becomes red, the material reaches 304, the potion becomes yellow or colorless, the material does not reach 304; M2 test 316 stainless steel energized point solution after the potion becomes red, the potion becomes black or red disappears instantly, the material does not reach 316).

 

304 and 316 have different performance

304 stainless steel can resist sulfuric acid, phosphoric acid, formic acid, urea, and other corrosion, suitable for general water, control gas, wine, milk, CIP cleaning fluid, and other corrosive small or non-contact materials.

316L stainless steel in 304 based on the addition of molybdenum, can significantly improve its resistance to inter-granular corrosion, oxide stress corrosion and reduce the welding of hot cracking tendency, it also has good resistance to chloride corrosion. Commonly used in pure water, distilled water, pharmaceuticals, sauce, vinegar, and other high health requirements, the media corrosion performance of the occasion.

 

Different ways of using stainless steel 304 and stainless steel 316

304 is mainly used in indoor and general outdoor environments, while 316 is used in the marine, chemical, food, and medical industries.

 

FAQ

1. Why can't the Gauss reach on some hopper magnets?

You can sprinkle some iron powder on the hopper magnet to make it easier to measure the Gaussian value

2. Why is there a slight bump on the magnetic rod surface?

The magnetic rod has a Gaussian value of 12,000 GS or more, and its internal magnet has a strong magnetic field, so it requires a larger sized magnetic sheet to make it, which causes a slight unevenness in the surface of the rod, but does not affect its use.
