Install magnetic separator magnetic blocks

Source:

Magnetic separator magnets in the choice of materials are usually made of two materials. One is strontium ferrite, molecular formula (SrO • nFe2O3), the other is barium ferrite, molecular formula (BaO • nFe2O3) magnet pole material from neodymium-Iron-Boron magnets, ferrite magnets, Alnico magnet, SmCo magnet four categories. We all know that most major components of magnetic separators magnetic materials, magnetic materials determines its performance characteristics. ND-Fe-b Magnet: neodymium Iron Boron magnet with the highest yet discovered are commercial properties, known as the King of magnetic, has a very high magnetic properties of the maximum energy product (BHmax) higher than ferrite (Ferrite), 10 times more than double. Its own mechanical processing performance is also very good. Operating temperatures of up to 200 degrees Celsius. But its hard, stable performance, there is a very good price, so its application is extremely extensive. But because of their chemical activity is very strong, so it must deal with the tinted layer on its surface. (Such as Zn,Ni coating, electrophoresis, passivation). Ferrite Magnet: ferrite mainly include BaFe12O19 and SrFe12O19. Process made by ceramics, hard texture, is a brittle material, due to ferrite magnets have a very good temperature resistance, low price and performance, has become the most widely used permanent magnet.
