Abstract:
1. A rotary particle separator for separating small particles from large particles from material comprising: a rotary inclined shaft having a first end and a second end; a particle feed bin coupled to the first end of such shaft and having a bottom surface, the bottom surface defining a hole to gravity feed the material from said bin along said shaft towards the second end; a plurality of annulae spaced along said shaft, each of said plurality of annulae having a central aperture encompassed by a ring defining an outer diameter, and having an arm mechanically coupling each of said annulae to said shaft; at least one paddle interspersed between two adjacent annulae of said plurality of annulae and rotating about said shaft; and a screen mesh having a mesh size, said screen mesh surrounding said plurality of annulae such that the small particulate has a small particle dimension less than the mesh size so as to pass through said mesh and leaving the larger particulate with a large particulate dimension larger than the mesh size within said mesh.
