Ball Mill  an overview ScienceDirect Topics
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.

How to Calculate the Mill Rate Sapling
A mill rate determines the amount of property tax each homeowner is responsible for paying. 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.
