Abstract
Apparatus providing samples for evaluating the sensitivity of bulk particulate solids to segregation when permeated by a gas. A plurality of stacked discs are rotatably mounted on a vertical shaft.Each disc has a bore, the bores being alignable to form a columnar sample chamber. A gas is introduced under pressure at the bottom of the chamber to fluidize the solids, inducing segregation. Apertures in the discs are adapted to support sample jars. The discs are independently and sequentially rotatable to cause the portion of the segregated sample within each bore to be separately deposited in a sample jar.
