Abstract

An apparatus for mixing animal feeds and the like comprises a rotor having two opposing end assemblies connected by a center shaft for rotation within a mixer box. A flighted outer auger is mounted in the terminal portion of each set of corresponding radial arms of each end assembly, parallel to the center shaft. Each outer auger is rotated by drive means within the first hollow rotor end assembly, powered by a high speed drive shaft, and the entire apparatus is rotated by a low speed drive shaft. The drive shafts extend from opposing end assemblies and are coaxial to the center shaft. An optional center auger or optional intermediately spaced augers, parallel to the center shaft, are rotated by drive means within the second end assembly, driven by one or more outer augers.
