The mine is closed and now you need to know how to put the SAG or Large Ball Mill in care and maintenance does not have to be complicated to the point where you need bridge erection equipment for lifting a Mill (AG/SAG/Rod/Ball). You actually need to lift a car higher than a mill. All you need to do is jack the mill up about 1/2″.
If you have done proper test work and assumed your Work index is as you provided above quickly I can estimate that your SAG throughput is around 517 t/h and if the total % of mill charge is 25 % of the total mill volume, then you can assume the following assumption .i.e. mass proportion of grinding body to ore be 15% steel balls and 10 % ore (1 ...
In all ore dressing and milling processes, including flotation, cyanidation, gravity concentration, and amalgamation, it is necessary to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent …
mill. As such, primary ball mills should be designed with the rod mill work index, and single-stage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, & Williams, 2006). On
How do you know if a larger SAG ball will increase your tonnage and how to select it? When is it time to change to a larger Ball in your SAG Mill? It's difficult to generalize on SAG mill ball size selection as it depends on a number of factors: Ore properties; Level of impact breakage in the mill (speed, lifter design, ball load) Grate …
