Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.
A SAG mill of diameter m and width m was charged to 40% of the mill volume with ore of SG when the porosity was 38%. With grinding time the ball load changed from 10% to 5% and the bed porosity to 12%. Estimate the change in power due to the change in mill conditions. The mill was run continuously at 70% of the critical speed.
On hard material the, power consumption, for a reduction ' ratio of 4:1, will average approximately one horsepowerhour per ton of hourly output; for example, a machine producing 50 TPH, handling 2″ feed, and set to ″ discharge spacing, will require approximately 50 HP drive it.

The optimization of comminution circuits has traditionally relied on wellaccepted comminution laws and ore hardness and grindability indices for ball/rod mills [9,10] and SAG mills [11,12,13].These comminution models are routinely used for optimized grinding circuit design, using averages or ranges of ore hardness tests of the mineral deposits to be extracted.
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^ where D m = the diameter of the singlesized balls in = the diameter of the largest chunks of ore in the mill feed in mm. dk = the P90 or fineness of the finished product in microns (um)with this the finished product is ...
