Material mixer

Image Number 3 for United States Patent #5249860.

A bulk material mixing apparatus has an inclined drum rotatably mounted on a frame supporting a hopper for directing bulk materials in the drum. An auger extended along a trough conveys materials toward the upper inlet end of the drum into a discharge chute or back into the drum. An elongated bar positioned above the auger provides an even distribution and flow rate of materials into the auger trough. A hydraulic motor drives the auger connected to a planetary gear drive used to rotate the drum whereby the motor concurrently drives the auger and drum to mix bulk materials placed in the drum. A hopper attachment having a feed auger is adapted to be mounted on the hopper to handle large amount of bulk material.
