Multi Grain Gravity Separator may be used to separate any type of dry bulk particles that are similar in size & shape but differs in weight. The machine consists of a rectangular deck for greater Separation efficiency and accuracy. The lighter particles move to the entire length of the deck, producing the cleanest light and heavy product fraction available. A dynamically balanced multiple fan system is individually adjustable giving the necessary control through different air settings to accomplish the accurate weighing necessary.
