feed size distribution is different to a standard Bond ball mill work index test. A series of 10 samples for an Andean copper project were treated to both the SAGDesign (and Sd_bwi) test and the standard Bond ball mill work index test with 180 µm closing screens. The SAGDesign results (with the non-standard ball mill feed) are given in Table 1.

The ball charge of a SAG mill is about 29% to 30%. By friction and influence of tumbling balls inside rotating cylinder grinds the raw material to the required fineness. The internal machinery of ball mill grinds the raw material into the powder-like material, And if extreme fineness and refinery are required then rotation go on continue.
The ball mill consists of a large cylindrical shell, typically made of steel or other materials, and lined with abrasion-resistant materials to protect it from wear and tear. Inside the shell, grinding media, usually steel or ceramic balls, are filled, the size and quantity of which can vary depending on the milling process.
