The headache of the manufacturer is that the material is not clean and the product can not pass the quality inspection. This is a common problem.

This is the pain point of the manufacturers mentioned at the beginning of this article. Every time the iron products removed from the purchase can not filter the iron slag, the product can not pass the quality inspection, how to change the situation,so that It can reduce the production cost and quickly solve the problem.

It is necessary to mention the key points, how to find a good magnetic filter bar manufacturer!

Purchasing a strong magnetic bar not only depends on the price, but also on the quality! The low-priced strong magnetic bar, the magnet with the refurbished magnetic material or the magnetic core is not the same size, the strong NdFeB magnet is replaced by the ferrite magnet, which leads to the price of magnetic bar is different on the market.

How do you know the difference between good and bad magnetic bars?

Sinoneo Magnets magnetic bar manufacturers master to give you some suggestions:

First, starting from the appearance, how to weld the two ends of the magnetic bar, whether there is strict welding, can not enter the water, if found to be able to enter the water phenomenon, which means that this magnetic bar is not a good magnetic bar, can not be used.

Second, starting from the magnetic line, holding the magnetic rod to roll a few times in the ground, the magnetic line will come out, then you can use the Gauss meter to measure the magnetic force, confirm if you can meet your requirements.

Third, starting from the size of the specifications, using a special tool to measure the diameter of the strong magnetic bar has not reached the size of the order at the time, the deviation is not serious, these all indicate the strength of the manufacturer and the attitude of doing things.

Once you know this, go and tell your company’s purchasing staff, you have the ideas to reduce production costs and make the materials more pure.

The stainless steel seamless tube and the outer frame form a solid whole through the skilled welding of the workers. It can be installed on the production line or simply placed in a hopper, material box and easily removed and cleaned. The Sinoneo magnetic grate(magnetic grid) is made of materials with a corrosion-resistant surface that meets the cleanliness of food and even pharmaceuticals. Our magnetic grate(magnetic grid) is usually arranged in parallel with a center-to-center spacing of 50mm with a diameter 25mm magnetic bar.
 
The application of magnetic grate(magnetic grid):

Magnetic filter holder (magnetic frame) is mainly used to filter ferromagnetic impurities in powdery, granular raw materials and liquids or slurries. It is widely used in ceramics, electric power, mining, plastics, chemicals, rubber, pharmaceuticals, food, environmental protection, pigments. , dyes, electronics, metallurgy and other industries.

The working principle of magnetic grate(magnetic grid):

The magnetic filter grate(grid) is made of stainless steel tube and high value rare earth alloy NdFeB magnets. And combined on a fixed frame to form a magnetic filter holder. When the iron-containing substance passes, it is attracted by the magnetic rod, and the iron-containing substance is firmly adsorbed on the pipe wall to ensure the integrity of the equipment and the cleanness of the product.

The features of magnetic grate(magnetic grid):

The magnetic frame has no energy consumption and can be installed at any position on the production line that can be in contact with materials. It saves space and is easy to install. It mainly uses rare earth neodymium magnets as magnetic source, good magnetic force, simple structure and long working life. The style,size and shape can be customized according to customer requirements and production conditions.

The magnetic filter frame is mainly used to remove iron impurities from the hopper, feed trough and floor space, which can effectively remove free flowing powder and iron impurities in small particles. The magnetic grate(magnetic grid) has a well-packaged magnetic bar that provides a high-intensity magnetic field to attract iron powder, iron filings, and other magnetically small pieces of metal in the flowing material. It can be installed on the production line or simply placed in a hopper, material box and easily removed and cleaned.

The common specifications of magnetic grate(magnetic grid):

Alnico can be cast into different shapes with various magnetic orientations. The rare earth Sm-Co and NdFeB magnets have high coercivity, so they do not need to be magnetized in circuit and can be used with low permeance coefficients (i.e. thin discs).

These materials also lend themselves to Helmholtz coil testing due to their straight line normal curves. This also makes rare earths ideal for SMC and high field dipoles. Sm-Co has a good resistance to thermal demagnetization but is brittle.

NdFeB is less brittle, has poor thermal properties, and is prone to corrosion.

They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). They are a relatively new invention and have only recently become affordable for everyday use.

1) The easiest way is to use another magnet that is already marked. The North pole of the marked magnet will be attracted to the South pole of the unmarked magnet.

2)  If you take an even number of magnets and pinch a string in the middle of the stack and dangle the magnets so they can freely rotate on the string, the North pole of the magnets will eventually settle pointing North. This actually contradicts the “opposites attract” rule of magnetism, but the naming convention of the poles is a carry over from the old days when the poles were called the
“North-seeking” and “South-seeking” poles.  These were shortened over time to the “North” and “South” poles that we know them as.

3)  If you have a compass handy, the end of the needle that normally points North will be attracted to the South pole of the neodymium magnet.

 The term “rare earths” is used to describe sixteen elements of the periodic table, including ytterbium, cerium, praseodymium, neodymium, samarium and lanthanum. These elements were initially thought to be quite rare, so they were brought together under this name. The first of these elements were discovered in the 1800s, and recent scientific advances that some of these items were actually not so rare after all. These elements have a number of interesting properties that make it a subject of study by the researchers and their potential use in magnets are one of these properties.

 These elements are linked with other elements such as iron and boron to make rare earth magnets, which are usually identify the primary elements of rare earth containing, as is the case of neodymium. The resulting magnets are very powerful magnetic field, which exceeds by far the most common fields of the magnets. Moreover, they are considered as permanent magnets, although the rare-earth magnet loses magnetic fields at high temperatures. Some are also very fragile, unfortunately, which means it should be used with caution because they can break down the explosive power.

 Two known examples of magnets are rare earth magnets and samarium-cobalt magnets. Neodymium rare earth magnets are among the highest of all the magnets, and they are relatively inexpensive, making them very popular. SmCo magnets are brittle and expensive, but they are also suitable for use at high temperatures because they do not lose their magnetism. This makes them popular in industrial production.

Since the rare earth magnet is so strong, it is important to be careful around them. They may interfere with the function of medical devices such as pacemakers, as well as causing havoc with electrical components. The magnets can also pinch your fingers or cause damage to their property due to their strong magnetic field, which attracts metallic objects. As is generally the largest magnet, the greater the risk, and people should be careful when they are more rare earth magnet and a large metal objects.
