System Design Variables For a dust collection system to function ade-quately engineers must design and operate the system to maintain the (4) key design parameters of CFM, FPM, Vacuum Pressure and Air to Cloth Ratio (or A/C). Changes to any of these key sys-tem parameters will result in systemwide perform-ance issues.

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 …

2.1: Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used.

feed stream in hammer mills for grinding tough materials. However, liquid nitrogen is seldom used in jet milling opera-tions due to the swift heat exchange between the material and the grinding gas. The grinding gas heats up the super-cooled feed stream, and the material loses its brittleness when it absorbs this heat. Stickiness.
