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.

If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.Mill Assessment Office,Mill Assessment Office About the Mill Assessment.
