Working Priciple of Centrifugal Sifter

When material is fed into the input port of the powder screen, a micro-auger pushes the bulk powder into the cylindrical screening chamber, where the powder tumbles inside the screen basket due to the fast-spinning paddles connected to the central drive shaft. A cage supports the screen, which can be removed for screen maintenance and replacement. As the paddles rotate, powder particles are thrown toward the screen. Particles smaller than the mesh aperture pass through the screen and are conveyed to downstream processes through the discharge hopper. Oversized particles travel along the length of the screen until they exit through the overweight or waste outlet.

What is centrifugal method of sieving?

Centrifugal Force: The material to be screened is placed in a rotating chamber. This rotation creates centrifugal force, forcing particles to hit the screen.

Particle separation: particles smaller than the screen opening will pass through, while larger particles are retained on the screen surface.

Compared to traditional gravity screening: Centrifugal force increases separation speed and efficiency to more accurately separate particles while minimizing contamination. Centrifugal force also helps prevent mesh clogging, a common problem with other screening methods
Advantages of Centrifugal Sifter

Handling powders, agglomerates and granules

Centrifugal force is used to separate particles of two different sizes. The centrifugal force generated by the paddle is also very suitable for breaking up agglomerates and agglomerated powders, and sieving to 530 mesh.

High productivity

The screening penetration rate can reach 85-95%, and the residue on the screen is 0 (which is difficult to achieve with ordinary vibrating screens). The screen area is 3.5 square feet and 6 square feet respectively, and the processing capacity is 5-10 times that of the vibrating screen.

Clean and hygienic

The fully enclosed construction eliminates dust problems, prevents dust leaks and protects operator safety.

No vibration and low noise level

Centrifugal sifter is very quiet and works without vibration, the sieve is very quiet, the noise level is below 80DB to be precise.

Quick screen change

The internal parts of the screen can be quickly disassembled without the use of tools, the screen change in 30 seconds, inspection and cleaning through the easy-to-remove screen.

Easy to clean

The internal parts of the sieve can be quickly disassembled without the use of tools, which allows for easy and fast cleaning.
