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.

The ball milling method: A ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum). The powder of a material is taken inside the steel container. This powder will be made into nanosize using the ball milling technique.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

Boron nitride nanosheets (BNNS) exfoliated by physical or chemical methods frequently exhibit poor dispersity in common solvents due to incomplete exfoliation and a low degree of functionalization, which has severely impacted BNNS application performances as polymer and lubricant additives. In this work, we mechanically exfoliated the bulk boron nitride into nanosheets through a ball-milling

To predict ball mill grinding behavior using the dis-crete element method, we must first be able to repro-duce the balls’ motion in the ball mill using simula-tions.

High Energy Ball Milling. It is one of the simplest ways of making nanoparticles of some metals and alloys in the form of powder. There are many types of mills such as planetary, vibratory, rod, tumbler etc. Usually one or more containers are used at a time to make large quantities of fine particles.

The major use of the conventional ball milling is to fracture the particles and to reduce the size, which is different from the newly established high energy ball milling (HEBM) method. In this new method a magnet is placed close to the cell to apply a strong magnetic pulling force on the magnetic milling balls, and therefore the impact energy
