Principles and applications of centrifugal sifters
Centrifugal sifter usage is expanding rapidly in terms of the number of installations and the types of applications served. While not suitable for all applications, centrifugal sifters provide substantial benefits -- particularly in terms of equipment size, throughput rate, and sifting efficiency -- than more traditional methods of separation. This article examines the operating principles of centrifugal sifters and discusses the key design parameters that affect their performance. The article also assesses the benefits and limitations of centrifugal sifters and highlights various applications.
Mechanical sifting or screening processes separate particles according to size alone. Using a screen or mesh to separate and classify particles is one of the oldest process techniques still currently practiced. In general, screening processes are divided into four main categories.
