Abstract
A mixer having an open top mixing box accommodating a pair of lower augers and a pair of upper paddle conveyors drivably connected to the augers. A power box pivotally mounted on one end of the mixing box is drivably connected to the augers with releasable drive connections. The power box is a motor driven power transmission assembly that can be disconnected from the augers and removed from the mixing box. A movable door associated with the bottom of the mixing box is used to selectively open and close a discharge opening allowing mixed and blended material to be discharged into a conveyor.
