Effect of mill type on the size reduction and phase

Sep 29, 2015 · Samples were degassed at 400 °C for a total of 4 h prior to analysis. BET particle sizes were estimated from specific surface area (SSA) by use of d particle (nm)=6/(ρ⁎SSA) where d particle is the particle size in nm, ρ is the density in gm −3 and SSA in m 2 g −1 is the specific surface area derived from BET (Rozita et al., 2013).

Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
