Introduction

How is the cross-sectional area of a sphere calculated? - QuoraA cross-section of a sphere is just a circle, so you would use the equation A=(pi)*r^2, where r is . is clear that r = RSin(t/2) from which the area can be derived, i.e. pi.(RSin(t/2))^2. The area of the cross-section is therefore a function of R and t.cross sectional area of ball mill,SAG Mill Grinding Circuit Design - Mineral Processing & Extractive .Jun 6, 2016 . AG mills (or SAG mills with low ball charges) are often used in .. typical mill lengths) while the available cross-sectional area grow's only as the.
