ABSTRACT:
In a device and method for particulating conglomerated materials, and especially soil samples, a revolving drum is mounted for eccentric rotation about a vertical axis. A grating or screen comprises the cylindrical wall of the open ended drum. The materials to be worked are placed between the outer periphery of the drum and an arcuate wall mounted for pivotal movement with respect to the drum. The materials are then crowded by the movable wall into engagement with the grating of the revolving eccentric drum to break up the materials into particles of workable size. Hard matter, such as rocks or gravel, is segregated during the process. If desired, a row of fingers and/or a brush can be mounted for engagement with the drum to loosen accumulated materials from the drum during operation of the device.
