Iron powder is the most used ferrous metal powder in powder metallurgy production. Its consumption accounts for about 85% of the total consumption of metal powder.
Generally, iron powder is divided into five grades: coarse powder, medium powder, fine powder, fine powder and superfine powder. Iron powder composed of particles with a particle size in the range of 150-500μm is coarse powder, with a particle size of 44-150μm as medium powder, 10-44μm as fine powder, 0.5-10μm as extremely fine powder, and less than 0.5μm as ultra-fine powder pink.
In the process of sieving iron powder, if the purpose of sieving is to carry out coarse sieving of iron powder, then a rotary vibrating screen can be used for coarse sieving to meet the demand, generally 80 mesh, 120 mesh, 200 mesh and other apertures are used. . But to carry out high-precision classification, it is necessary to choose an ultrasonic vibrating screen.
Which type of vibrating screen to choose, we need to combine the actual output and material conditions of customers. However, the rotary vibrating screen produced by our company has been well received by customers at home and abroad, especially the screen part, taking into account the effect of iron powder on the vibrating screen For the abrasiveness of the screen, the vibrating screens we use in the iron powder industry all use the abrasive-grade screens of military enterprises, which can effectively extend the service life of the screens while ensuring the special standards of the mesh.
