ELICA Gravity Table is used for sorting seeds similar in size with different relative weight. The separation is performed on the principle of vibration and air. A fan creates an air “bed” where lighter particles “float” and are directed down the slope of the screen. The heavier particles remain in contact with the screen which through vibrations transfers them to the upper part of the working area.
On the top of the dome made of fibreglass, there is an opening for aspiration and two inspection windows. The machine has three outlets- one for the clean product, the second for the unwanted impurities. The third outlet can be either open or close for an optional second pass of a fraction that still contains impurities. The inclinations of the frame which are specific for each product can be easily regulated.
This type of gravity table is usually installed for processing crops which do not create dust. Its method of separation incorporates a number of small valves which can be adjusted independently from each other. This makes the setting more precise and allows the separation of more fractions.
