As mentioned earlier, pebble mills are widely used in the North American taconite iron ore operations Since the weight of pebbles per unit volume is 35-55% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower.
The ore is then conveyed to a covered storage building that is lo-cated along the entire northern portion of the grind-ing and concentrator facility When the ore is ready to be processed, it flows by gravity into the facility onto one of 12 conveyors lines which brings the ore up a slope that feeds a primary grinding.
