  • Crushing, Grinding and Reduction in Flour Milling

    Grinding gap and particle size are reduced towards the end from roller mills which the grinding begins. The reason for this is that each process has disintegration and contraction while making gradually cutting, sorting and scraping actions during the separation of endosperm and bran. Therefore the grinding gap will be less in the next crushing process. This range varies depending on the

  • Ore processing Waihi Gold

    The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel
