### Power Consumption In Sag Milling

A Mill Power Equation For Sag Mills NIZZI SARA Modelling SAG milling power and specific energy. Two new SAG milling models are developed in this work, able to predict power or specific energy consumption, including the usual design variables such as mill size balls charge level, solids concentration in the SAG mill feed and of critical speed

Ball Mill - Slideshare. Nov 18 2008 Equations of the design By knowing the capacity quot;Cquot; {ton} of the feed; we can get approximately the length quot;Lquot; {mm} and diameter quot;Dquot; {mm} of the batch ball mill form D 124.2C 485.7 L 85.71C 1854 Volume of mill 2 The bulk volume of balls charge ratio to the volume of mill is known as {Filling ratio} and its range is {30-45} 2 Note

Equipment Design Equation Ball Mill

The milling process – definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters
