Ball Mill Design/Power Calculation
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed ...
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.

Calculating Power Draw when sizing Ball Mills - …
Calculating Power Draw when sizing Ball Mills (16 replies and 1 comment) (unknown) 5 years ago (unknown) 5 years ago. I’m interested to know when sizing a new ball mill, as to why recirculating load has no effect on the power calculation, although it will have effect on volumetric capacity naturally. For instance a mill of 300tph with a 300% recirculating load would have 1200 tph going ...

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 ...

Optimization of mill performance by using
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
