Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

Turbine power and efficiency. The turbine power calculator outputs the power output of your small turbine in watts and milliwatts. All you need to do is measure your voltage across a known resistor. If you know how much power you are generating, the wind speed, and how long your blades are, you can calculate the efficiency of your turbine.

from 5 effect to 6 effect and of $3.3 million from 5 effect to 7 effect. The payback calculation will be different based on the specific mill conditions. If the mill is self-sufficient in steam from the recovery boiler and while firing only wood waste in the power boiler, then the steam saved can be used to produce additional power.

In general, therefore, the required mill power is calculated using the following equation. where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill size and type can be selected.
