SAG Mill Ball Charge The SAG mill was simulated to require a 10-12% ball charge with a top size of 125mm. During the commissioning phase no balls were required to be added to the SAG mill to achieve the target throughput of 575tph. This allows for great flexibility in the future and significant security for the future. Ball Mill Power

autogenous mills grind by impact, whereas ball mills do so by attrition. As a consequence, SAG mills have been designed and operated to generate a large number of impacts by the falling load, without paying much attention to the place where these impacts are occurring. A second consequence has been that as long as the mill is consuming
