For instance, high energy ball milling is a top-down method using planetary ball mills. To obtain optimized milling parameters in a planetary ball mill, many trials are needed. Hence optimization of the milling parameters through modeling tools is necessary to reach economically efficient and time-saving synthesis of nano-fertilizers.

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

The design of ball mills was described back in the 18th century—and the principle of their operation has not changed; the only significant changes are the increased diameter and some new solutions for the mill's drives introduced. Energy consumption in ball and rod mills reaches up to 10–20 kWh per ton of rock.
