ABSTRACT:
An apparatus for sampling a flow of heterogeneous material falling under gravity comprises a rotating table adapted for rotation about a support column, a plurality of removable sampling passageways of identical aperture size mounted side by side around the periphery of the rotating table and adapted to cut the flow of material and a motor for driving the rotating table at constant velocity. The sampling passageways include deflection- and straight-type passageways and the number of deflection-type with respect to straight-type passageways is proportional to the desired percentage of sample to be retained.
