Turbo Sifters use a combination of rotary screw & centrifugal actions. These are used mainly for sizing & de-lumping. Sieve parameters like the size & shape of the aperture, pitch & thickness play a very important role in material processing.

Sifters usually use vibration energy or a combination of Vibration & ultrasonic energies to achieve screening. Sieves have to be specially designed to resist the high tensile stress generated. Since Particle Size Distribution plays a vital part in drug dissolution, maintaining the accuracy of the sieve apertures is an essential part of sieve manufacturing. Proper thickness of wire, accurate nominal aperture sizes, high tensile strength & tautness of the sieve are essential for high sifting performance.

Centrifugal action can achieve a high volume of screening with a small machine footprint. These are mainly used for Check Screening but can also be used for sizing & separation. Sieves are designed to withstand the high stress forces generated and apertures and sheet thicknesses are carefully selected for maintaining proper throughput & particle size distribution
