### Ball Mill Motor Power Draw Sizing and Design …

The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A. Rowland and D.M. Kjos @ Allis-Chalmers

### CALCULATION OF THE POWER DRAW OF DRY …

calculate the power that each ball mill compartment should draw. The total power is the sum of the power calculated for each of the separate compartments. Although, Bond’s method has been widely used, the required link to classification is missing. Therefore, it is not possible to calculate circuit performance when any of the design and operational parameters are changed (Napier-Munn et. al ...

### Wind Turbine Power Calculator - Rechneronline

Wind Turbine Power Calculator. Calculates the power of a wind turbine from size, wind speed and air density. The radius is the length of a rotor blade. The wind speed refers to one point in time, not to an average speed. Air density, which is the mass of air per space, depends on air pressure, temperature and humidity. 1.2 is a good average value at sea level (air density calculator in German ...

### How to Calculate Water Wheel Power | Sciencing

Multiply the hydro power by the units efficiency rating, usually listed as a percentage in its specifications. In the example, if you had an efficiency rating of 60 percent, then you would divide that number by 100 to convert it to decimal format. Then multiply that number by the hydro power of 4,905 watts to calculate the water wheels power of 2,943 watts.
