Crushing. Once gold-rich ore is excavated, it needs to be crushed into a fine powder before it can be processed. The initial crushing is done by hand with makeshift hammers, almost exclusively by women. Ball mills- tumblers full of steel balls- complete the final stage of crushing, producing finely ground ore-powder.
The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 26 and 220.
