ABSTRACT:
The present invention is a sample splitter used to divide a larger sample of particulate material into representative smaller portions. The device uses a fixed conical sample splitter oriented with it apex upwards. Resting on this and translatable upwards is a sample receiving hopper. The hopper has open top and bottom ends. When receiving a sample to be divided, the bottom of the hopper rests on the splitter cone to form a sample retaining seal. When the hopper is raised, the sample falls by gravity around the splitter cone. An appropriately sized sample receiver located below the splitter cone receives the desired fraction. A generally cylindrical skirt is coaxially located below the splitter cone. The sample receiver is preferably a sector shaped drawer entering the skirt from the side.
