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 biggest feature of SAG mills is the large crushing ratio, which can crush and grind the materials to 0.074mm at one time, accounting for more than 20% to 40% of the total product. The crushing ratio can reach 4000 ~ 5000, which is more than ten times higher than that of the ball mill machine and rod grinding machine.

The design of ball mill drives is, in many ways, more difficult than for AG and SAG units. This stems from the fact that the ball mill is generally smaller in diameter, so that the notional tangential force at the shell is higher for a given power input (although this effect is somewhat offset by the ball mill's higher rotational speed).
