Abstract
A device and method for separating particles by mass is provided in which the particles are entrained in an airstream and are ejected into a collection zone where they will fall under the influence of gravity, but will separate longitudinally by mass with the most massive particles traveling the farthest. As an enhancement to the separation, an apparatus for forming at least one air curtain perpendicular to the ejection direction is provided which causes the falling particles to separate into discrete groups.
