Abstract: A sampler for obtaining small samples of material from a flow of bulk material as it is transported past a sampling station, is characterized by a sample collecting scoop which is rotated in an arcuate path through the material about an axis inclined at an angle with respect to the major plane of the material. The scoop moves through the material generally in the direction of material flow and at a speed slightly greater than that of the flow, and by virtue of its inclined axis of rotation has components of motion therein both vertically and transversely of the material. In consequence, even if the material is segregated the sample obtained by the scoop is a true representation of the material. After leaving the material, the scoop is then rotated to a sample collection point above and transversely to the side of the material, whereat the sample is deposited in a container. A number of such samples obtained from different parts of the material flow may be combined to build a representative composite sample, which is then analyzed to determine the overall composition of the bulk of material.
