Centrifugal sifter is a rotary screener designed to separate particles of different sizes into two product streams and remove impurities and oversized materials, it can continuously screen powdery materials in the range of 80-530 mesh (common vibrating screens are difficult to Screening and grading of powdery materials above 200 mesh), even when dealing with materials that are prone to peeling or clumping due to fat or moisture content, the combination of high centrifugal force and blade spreading action reduces sticking problems, and the output is ordinary vibrating sieves 5-10 times.
