TopDown Method: Production of nanoparticles with ball mills Nanoparticles are created with the TopDown method by colloidal grinding using a suitable dispersant to keep the particles from agglomerating. To reduce small particles with mechanical force to even smaller sizes, a high energy input is required. The

The synthesis of silica nanoparticles using the mechanical milling method was observed by Wahyudi et al. [Citation 30]. Highgrade results were achieved by using the planetary ball mill for 30 hours with an average particle size of 80 nm. Although the method generates a very fine particle size, it produces particle agglomeration which can ...
The macrosized particle formation can be done using different mills such as ball mills, hammer mills, colloid mills, fluid energy mills, and roller compression mills. But, for nanoparticles, it is best suited using ball mills based on energy requirements which are further classified as mentioned in Table (Sherif ElEskandarany et al., 2021).
There are various techniques for the synthesis of nanostructure materials (and/or nanoparticles).
