ABSTRACT:
A rotating riffler for the purpose of withdrawing smaller laboratory-sized representative particulate samples from larger samples. This comprises a rotating disk having an interchangeable top plate of plastic foam having openings therein to accommodate sample containers. Where different size sample containers are employed, the plastic foam plate is changed to accommodate them. The rotating disk is mounted on a base containing a variable speed drive and is supported at the periphery by bearings rather than by the shaft. A slurry or dry volume of particles of which a smaller representative sample is required, is fed into a funnel-like device, then drops in a controlled flow into the sampling containers rotating below the funnel. "V"-shaped bridging devices having curved legs are attached between each pair of containers to prevent spilling.
