The crushed ore is transferred to a grinding mill, which contains heavy-duty steel balls or rods. As the mill rotates, the balls or rods crush and grind the ore, resulting in the formation of a fine powder. The purpose of crushing and grinding the gold ore is to liberate the valuable gold particles from the surrounding rock and minerals.
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …
