gold, iron, and molybdenum ores, may require as much as a tertiary crushing. To design a good crushing plant one has to follow these three steps: crusher selection, crusher layout and process design. 2.4 Crushers . A crusher is a tool or machine that is used to reduce the size of a large solid particle to a smaller solid particle. The
emission factors for the crushing, screening, and handling and transfer operations associated with stone crushing can be found in Section 11.19.2, "Crushed Stone Processing." In the absence of other data, the emission factors presented in Section 11.19.2 can be used to estimate emissions from corresponding sand and gravel processing sources.

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.

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.

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 …
