ABSTRACT:
An apparatus for sampling a portion of flowable solid material from a stream thereof is provided. The apparatus includes a plurality of nested stage assemblies enclosed within a housing for sampling successively smaller portions of the solid material flowing therethrough. Each stage assembly includes a conical upper section, a funnel shaped lower section and a substantially cylindrical section disposed therebetween and defining a chamber for receiving a sampled portion of the flowable solid material. Each cylindrical section includes a plurality of openings and removable splitter assemblies for directing the sampled portion into the chamber. Each splitter assembly includes a front wall and opposing side walls defining a mouth for receiving a portion of the flowable solids and flow path through said chute. The front wall widens from the mouth to define flared side walls and an increasing area through which the solid material flows toward the chamber. An outlet tube receives and directs a desired sampled portion of the solid material away from the primary flow.
