1 Introduction. In mining, a Semi-Autogenous Grinding mill (SAG) is the equipment used at mineral processing plants in the size reduction process, making the ore suitable for the next stage of flotation. Its use lies in significant processing and reduction capability offered by this kind of mill, where maximize the operational continuity and ...

Replacing the SAG's worn-out liner can occur every six to nine months and cost between $30,000 U.S. and $200,000 U.S. per hour, and each repair takes between 40 hours and 120 hours. Obviously, optimizing liner design along with operating processes can result in significant savings. To achieve SAG mill equipment optimization, you should ...
