The vibro aifter machine works on the principle of gyratory vibrations. The material is separated based on its particle size. Once the motor gets energized, vibration is caused in the screen/sieve making the material travel across the sieves according to its particle size.

In three different planes, the development of vibration along the vertical axis utilizing a specially designed vibratory motor that meets various output requirements. It causes 100% rotary motion and causes dispersion stirring & amp; stratification of material to sift. Feed material flows in Horizontal movement along with a loop pattern on vibro screen.
