Rod magnets are also called bar magnets. Rod magnets are mainly used to filter various fine powders and liquids, iron-containing impurities in semi-liquid and other materials with magnetic properties, and are widely used in chemical, food, waste recycling, carbon black and other fields.
The rod magnet is composed of an inner magnetic core and an outer cladding. The magnetic core includes a cylindrical magnet block and a magnetic conductive sheet. The entire rod-shaped magnet is generally placed in a moving product transmission line, and the surface of the rod-shaped magnet should slide less, to exclude substances harmful to the environment, and avoid impurities and the environment.
The working environment of the rod magnet determines that it must have certain corrosion resistance and high temperature resistance characteristics, and there are occasions where a relatively strong magnetic induction intensity is required. Different magnetic flux density can be obtained by using magnetic conductive sheets of different thickness. Choosing different magnets can determine the maximum magnetic induction and temperature resistance of the rod magnet. Generally, to achieve a surface magnetic induction of 12000 Gauss or more on a conventional 1-inch diameter rod magnet, a N40 or higher model neodymium iron boron magnet is required. Samarium-cobalt magnets are generally selected for high-temperature resistant rod magnets when the temperature exceeds 150 degrees. However, samarium cobalt is not chosen for large-diameter rod magnets. After all, the price of samarium cobalt is very high, and the price of a rod magnet with a diameter of 50 * 500 reaches trillions.
The surface magnetic induction intensity of rod magnets is proportional to the smallest particle size that can be absorbed. Small iron impurities can also have a great impact in the fields of batteries, pharmaceuticals and other fields. Therefore, it is necessary to replace the rod magnets of about 12,000 Gauss. Other areas can be replaced with lower ones.
When the rod magnet is in contact with fluid, there will be some irreversible loss of internal magnetic energy. The loss exceeds 30% of the initial strength or the iron sheet on the surface. When the stainless steel pipe ruptures, you need to replace the rod magnet without leakage. The rod-shaped magnet of the magnet continues to work. The magnet is generally brittle, and the surface is also coated with some oil, which will pollute the environment. Domestic rod magnet manufacturers generally can work under heavy load for 1-2 years, and light load for 7-8 years.

Features of rod magnets

Super strong rod magnets are characterized by dense poles for effective iron removal, large contact area and super magnetic force. The iron removal container can be customized and processed according to user requirements.
All rod magnets are equipped with stainless steel protective sleeves, which effectively protect the rod magnets from damage. Discharging iron is convenient and quick; pull the rod magnet, and the ferromagnetic substance adsorbed on the rod magnet is automatically separated. Continuous work; raw materials can continue to work when the iron is drawn out layer by layer, without the need to pause feeding.
