Specific Gravity Separator 1.2 Tph & 2 Tph



The Gravity separator separates products of same size but with difference in specific weight. … The pressurized air in the deck enables the material to split according to its specific weight. As a result, the heavier particles travel to the higher level while the lighter particles travel to the lower level of the deck.

They can be used effectively to remove partially eaten, immature and broken seeds to ensure maximum quality of the final product.


Working Principal ;

These Gravity Separators have a rectangular deck so that the product travels a longer distance resulting in cleaner separation of light and heavy particles and the lowest percentage of middling’s.

The product flows over the vibrating deck in which pressurized air is forced through causing the material to stratify according to its specific weight. The heavier particles travel to the higher level and the lighter particles travel to the lower level of the deck.

In order to obtain efficient separation by specific weight, the pressurized air supply needs to be accurately adjusted and this is accomplished by having individually adjustable air fans to control the volume of air distribution at different areas of the vibrating deck. The table inclination, speed of eccentric motion and the feed rate can be precisely adjusted with ease and minimum of operator training.


This machine is specifically meant for removing impurities and achieving very high grading quality in any free flowing granular material, like all types of seeds, grains, spices, pulses etc. This machine is available in various capacities ranging from 1 TPH to 2 TPH.
