dard Circuit, assume m diameter overflow mills, and use a rod mill F80 of 16,000 µm and a rod mill P80 of 1,000 µm. Note that—in order for no correction factor for ball mill product fineness to apply—the ball mill circuit P80 should be no less than approximately 70 µm (Bond, 1962). This
How to Calculate the Mill Rate | Sapling
Calculate your mill rate to determine the amount of property tax you owe. This tax amount is expressed as one dollar for every 1,000 of assessed property value; mill or per mill means per thousand. Property taxes are often expressed this way by municipalities, so it can be useful to understand how the mill rate is calculated.
