ABSTRACT:
Apparatus for extracting one or more individual samples from a free falling stream of bulk material by a suitable cutter that traverses the falling stream of the bulk material to collect a test sample and move it to a point where the sample can be delivered into a crusher and mixer-feeder for preparing the crushed material for handling to obtain therefrom a final quantity that is suitable for being subjected to a process whereby information characteristic of the bulk material may be determined.
