Abstract: A system for conditioning bulk material comprising a mixer having a mixing chamber and motor means driving a rotary mixing element in the chamber; an automatically controlled discharge system for discharging material from the chamber at a selected constant rate, the discharge system comprising an outlet opening formed in the mixing chamber, a discharge door adjacent the opening mounted for reciprocal vertical movement between a closed position covering the opening and an open position uncovering the opening, and a fluid motor for normally maintaining the door in a fixed neutral position partially uncovering the opening and operable to move the door out of the neutral position when a selected variation in load on the motor means is exceeded and to return the door toward said neutral position when the variation is no longer exceeded.
