Sifters usually use vibration energy or a combination of Vibration & ultrasonic energies to achieve screening. The MESH are held in tension, making it easier for material to move in the direction of the vibration. This could be in horizontal or vertical direction, Depending on the type of material you wish to process, the screen structure uses the FDA approved seals to prevent cross contamination of the products in sieves. 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
