The principle used is stratification of the product
into heavier and lighter fractions by forcing air through the bed of
material.This is achieved by means of pressure fans located in the body
of the machine, below the vibrating deck. 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. Alladjustments can be made with ease and minimum of
operator training.
Features:
- Can be connected to a central aspiration system
- Provided with clean product and stone discharge spouts.
- Windows provided for product viewing
- Deck inclination and vibrating speed steplessly Adjustable
- Easy control of airflow and feed rate.
Spectrum Pressure Destoner are used for separating heavier materials like
stones, glass, metal etc. From food grains and other dry granular material.
