Vacuum Type De-stoner

These Vacuum Type De-Stoner are used for separating heavier materials like stones, glass, metal etc., from food grains and other dry granular material.
The principle used is stratification of the product into heavier and lighter fractions by forcing air through the bed of material.
The vibration of the deck is achieved by means of unbalanced vibratory motors mounted at the centre of the machine.
The Vibrating deck pushes the heavier material in contact with the deck upwards towards the stone discharge spout.
The lighter material flows down the inclined, vibrating deck and exits through the clean product spout.
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 applications. All adjustments can be made with ease and minimum of operator training.
