摘要： Apparatus for feeding balls to a grinding mill. The apparatus includes a downwardly inclined chute (12) adapted to receive balls from a bin or hopper, the chute for delivering the balls to the grinding mill and means (20) for sequentially feeding the balls, one-at-a-time, to the grinding mill. The feeding means includes a first actuator (22) and a second actuator (26). Each of the actuators preferably includes an extension arm (24 and 28 respectively) mounted for rotation along the longitudinal axis of the chute. The first actuator is for restraining balls from traveling down the chute and works in conjunction with the second actuator for isolating the lowermost ball in the chute to be fed next to the grinding mill. The second actuator is for releasing the isolated ball. The feeding means may include a computer controller (90) for operating each of the actuators at a predetermined time interval corresponding to the ball attrition rate of the grinding mill. A magnetic sensor (84) may be positioned inside the chute downstream from the actuators for sensing passage of the isolated ball through the chute for providing feedback to the controller.
