From food grains and other dry granular material.

The principal used is stratification of the product into heavier and ighter fractions by forcing air through the bed of material.The vibration of the deck is achived by means of unbalanced vibratory motor mounted at the centre of the machine.

The inclination of the vibrating deck and the stroke of eccentric motion can be finely adjusted to achieve the optimum degree of separation.

A wide variety of deck screens are available to suit specific application
All adjustments can be made with ease and minimum of operator training.
