Although there is no limit set, the downsizing process over 3 mm is considered as "crushing" and the ones below 3 mm are considered "grinding". Even though the ore is reduced below 3 mm with conical and some impact crushers, this process is called crushing. The process of size reduction is defined by below conversion formula:
