Read MoreJan 23, 2020 For a rough idea, start by adding 50 to 70 to your cost figure excluding timber of 450. You can then subtract that total from the estimated price you can charge for lumber 800 in our above equation. For example 450 x 1.5 675 per thousand board feet. 450 x 1.7 765 per thousand board feet..For overflow ball mills, the charge should not exceed 45 of the mill volume . For grate discharge mills, the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
