ABSTRACT:
A spin riffle sampling apparatus distributes a sample source quantity of particulate material in a predetermined number of increments, 60 for example, to each of a smaller number, 4 for example, of radially disposed bins on a rotating platform. The bins include top openings which pass through a falling zone of material to receive material into the bins. The width dimension of each opening decreases with increasing radial displacement from the axis of rotation of the platform. The bins also may be forwardly pitched relative to the direction of rotation of the platform so as to induce a down draft to control dusting.
