ball milling for nanoparticle synthesis. For instance, high energy ball milling is a topdown 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 timesaving synthesis of nanofertilizers

Most nanofertilizers are synthesized by a bottom-up approach, which is a complex and requires sophisticated instruments. The top-down approach is an alternative method for large scale and low cost of production. For instance, high energy ball milling is a top-down method using planetary ball mills.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
