Abstract
A particulate material mixer has a rotatable drum with an inclined longitudinal axis. A conveyor having an open top trough and auger is located longitudinally in the drum and operates to move mixed material from the drum chamber into a hopper or alternatively back into the chamber. A drive transmission simultaneously rotates the drum and operates the conveyor. A flexible circular seal interposed between an annular end wall and a circular wall of the drum prevents material from spilling out of the drum. The conveyor trough is mounted for angular movement to regulate the volume of material discharged from the mixer. A manually operated liner actuator allows the operator to select the angular position of the trough. The hopper has a discharge door and chute to direct mixed material away from the mixer to a desired location.
