A material discharge regulating gate, for a rotating material processing drum, having a vertical circular member having a diameter larger than the discharge end of the drum, the circular member having a continuous surface with a material discharge opening therein, and means for rotatably mounting the circular member adjoining the discharge end of the rotatable drum. Apparatus comprising a rotatable material processing cylindrical drum having a substantially horizontal axis and a circular discharge open end, a material discharge regulating gate adjoining the discharge end of the drum, said gate comprising a vertical circular member having a diameter larger than the discharge end of the rotatable drum, the circular member having a continuous surface with a material discharge opening therein, and means for rotatably mounting the circular member adjoining the discharge end of the rotatable drum to rotate independent of the drum. A method of regulating and controlling material flow or discharge from a rotating drum by positioning a vertical circular member at the discharge end of a rotatable drum, the circular member having a continuous surface with a material discharge opening therein and also having means for rotatably mounting the circular member adjoining the discharge end of the rotatable drum, rotating the drum, feeding material to the rotating drum for processing, and after processing discharging the material from the rotating drum with controlled flow by rotating the circular member to position the opening at a stationary location to effect controlled flow material discharge from the rotating drum through the opening in the circular member.
