As grinding media gradually depletes in the ball mill, so does the power draw. Deviation for a set point then activates the machine to dispense grinding media into the weigh hopper, where it is reordered prior to a pneumatic gate opening and allowing it to discharge in the feed hopper to compensate for the weight of balls required to restore ...
In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.

— SAG mills have a higher installed power density for a given plant footprint relative to AC mills. With the combination of finer grind and a lower installed power density (based on the lower density of the mill charge), a typical AG mill has a lower throughput, a lower power draw, and produces a finer grind.
