Abstract
A rock crushing assembly is provided in the form of a pulverizing tumbler. The apparatus includes a faceted tumbler having a plurality of faceted end walls, a pair of parallel sidewalls, and an open interior. A power source and a drivetrain assembly attach to the sidewalls of the tumbler and rotate the same. Within the tumbler is adapted to be placed rocks and minerals to be pulverized, wherein pulverizing media is placed in the tumbler with the rocks to break down the rocks into fine, granular material. One of the end walls of the tumbler is removable to allow access to the tumbler interior. One or more gaps or apertures through one or more of the end walls allow the pulverized material to exit the tumbler during operation, thereby reducing build-up of loose material that can dampen impacts within the tumbler.
