Mechanical Sifter


In recent times the most important development that took place is the replacement of the conventional reciprocating motion by the gyratory motion in the sieving and straining operation. This machine is designed to provide gyratory vibration generated by means of balance flywheel. The amplitude of vibration is adjustable to the processing needs by means of movable weight on the flywheel. This ensures that every point on the screen surface continuously transverses a circular path in horizontal plane with the elimination of the vertical motion.

This is the only movement capable of effectively presenting in turn all the faces of irregularly shaped particles to the apertures of the screen. Again due to the absence of the vertical movement, bouncing of particles does not take place and thus presenting clear screen apartus.

It is difficult to indicate specific data on the proper amplitude of gyration, for a specific product. However, it has been found that straining operation of liquid & solids calls for lower amplitude to avoid splashing unless the viscosity and tension of the liquid is high.
