Density Separation

Gravity tables and dry stoners.

Gravity Tables and Dry Stoners are designed using air to stratify products into various layers according to their bulk density.  Through conveyance, these layers are separated from one another allowing heavy products to travel up an inclined deck, while light material travels down the deck. Often times, a product that may be similar in shape and color can be separated by density.  Thus, light and heavy impurities can be removed.
