An apparatus for mixing materials includes a cylindrical drum having a mixing chamber with a longitudinal axis, an inlet end having an opening open to the mixing changer, and a closed end for holding materials, a hopper located adjacent the inlet end of the drum for directing materiasl through the opening into the mixing chamber, a frame for supporting the hopper, a planetary gear drive supporting the drum for rotation on the frame about the longitudinal axis thereof and inclining the drum and the axis downwardly from the inlet end thereof, a trough having an open top located in the mixing chamber, an auger in the trough for moving materials along the trough toward the inlet end of the drum, a drive mounted on the hopper for rotating the auger, the planetary gear drive having a shaft connected to the auger and a rotatable member connected to the drum whereby the drive rotates the auger and operates the planetary gear drive to rotate the drum, means mounting the planetary gear drive on the frame adjacent the closed end of the drum, a bar mounted on the trough above and extended generally parallel to the auger to provide substantially even distribution of materials moving into the trough and to restrict the amount of materials that move into the trough during rotation of the drum, and means located below the hopper to allow materials discharged by the auger from the trough to selectively flow back into the mixing chamber or flow out of the drum to a selected location.
