Abstract - USGS

OPERATING COSTS. Operating costs are based on daily capacity (st/d) and are expressed in dollars per short ton ($/st). The open pit models are based on X = st/d of ore and waste moved. This allows for the wide variability in stripping ratios found among different open pit operations.

Small Ball Mills for Sale - 911Metallurgist

The calculated liner and ball wear is expressed in kilograms per kilowatt-hour (kg/kWh), and when multiplied by the specific power (kWh/t), the wear rates are given in kilograms per ton of feed. The wear in dry ball mills is approximately one-tenth of that in wet ball mills because of the inhibition of corrosion.
