Centrifugal Sifters

Centrifugal sifters, also known as rotary screeners sift, filter, and separate particles from a bulk material. They are often used to remove unwanted particles from a product, to grade particles according to their size, or to separate different materials.

Available in dual configurations and sizes that can sift up to 100 TPH, these sifters from Kason are widely popular.

Operating Principle

Centrifugal sifters use centrifugal force to separate particles from a material. The material is fed into the sifter, and as it rotates, the centrifugal force causes the heavier particles to move towards the outer edge of the screen while the lighter particles remain in the center. The screen separates the particles, and the desired size range is discharged through the screen while the unwanted particles are rejected.


Centrifugal sifters come in a variety of sizes and configurations, making them suitable for many different applications. Some of the options include:

  • Screen Material: The screen material can be made of various materials including stainless steel, polyurethane, or wire mesh.
  • Screen Size: The screen size can range from small to large, depending on the desired particle size range.
  • Drive Mechanism: Centrifugal sifters can be driven by an electric motor, air motor, or hydraulic motor.
  • Screen Configuration: Not only can centrifugal sifters can have one or multiple screens to allow for multiple stages of separation, but the screen itself may need to be customized beyond perforation size and spacing. Perforation shape, roughness, or direction of perforations if rough can all greatly impact performance depending on the material.
  • Dust Collection integration: Some centrifugal sifters come equipped with a dust collection system.

When to Use Them

Centrifugal sifters are most commonly used in applications that require separation of particles based on size. Some of the most common applications include:

  • Food processing: Centrifugal sifters are used in the food industry to remove unwanted particles from food products, such as foreign objects, over-sized particles, or under-sized particles. This included de-watering.
  • Pharmaceuticals: In the pharmaceutical industry, centrifugal sifters are used to separate and remove unwanted particles from active pharmaceutical ingredients.
  • Chemical Processing: Centrifugal sifters are used in the chemical industry to remove over-sized or under-sized particles from a material.
  • Minerals and Metals: In the minerals and metals industries, centrifugal sifters are used to separate valuable minerals or metals from waste materials.

When Not to Use Them

Centrifugal sifters are not suitable for all applications and there are some situations where they should not be used. Some of the disadvantages of centrifugal sifters include:

  • Heat Sensitive Materials: Centrifugal sifters generate heat during operation and can cause heat-sensitive materials to degrade.
  • Fragile Materials: Centrifugal sifters generate high amounts of mechanical energy, which can cause fragile materials to break.
  • Large Particles: Centrifugal sifters may not be suitable for separating large particles from a material as the high-speed rotation may cause the large particles to become trapped in the screen.

There is some wiggle-room regarding these types of products and conventional knowledge, so our sales team will help you understand if there are any mitigating strategies available for your material.
