Abstract
A mixture of botanical fines and sand is separated by a porous separating medium horizontally disposed within an enclosed chamber in which an upflowing stream of gas carries out the separation. The porous separating medium is comprised of a plurality of particles constrained in a close-packed array between two opposed retaining members. While the gas flows up through the array of particles they are subjected to vibration, the separation being primarily determined by the flow of gas through the array and mobility of the particles. The separation is primarily controlled by altering the volume constraining the particles in the array which affects both the velocity of gas flow and the mobility of the particles.
