Technical Parameters

Our AD, AF and 2AFF models rectangular gyratory screen sifters are suitable for Fine Screening with large capacity and high accuracy. The accuracy is more than 90%. They are often used to screen quartz sand (silica sand), frac sand, ceramsite sand, petroleum coke, activated carbon, urea, plastic particles, sugar, salt, soybeans and other materials.

Screen Structure	√ Grommet screen, use clips to tension the screen surface. The screen surface is automatically tensioned, which is conducive to the material passing through the mesh	Hook screen, use hook plates on the left and right sides to tensify the screen. The screen surface may appear fluffy in the middle, which may affect the material through the screen	Hook screen, use hook plates on the left and right sides to tensify the screen. The screen surface may appear fluffy in the middle, which may affect the material through the screen
Screen Replacement	Similar to linear vibrating screen, have to take out the screen frame that needs to be replaced and all the screen frames of the upper screen layers	Just replace the screen of the layer that needs to be replaced	Just replace the screen of the layer that needs to be replaced
Mesh Deblinding System	Use silicone balls to clean the mesh. The ball deck usually uses woven wire mesh (light). And it can also use perforated sieve plate	Use silicone balls to clean the mesh.
