Ultrafine Grinding - an overview | ScienceDirect Topics

Ultrafine grinding or nanosizing terms were frequently used for the process, when the size of the particle lies in the range of nanometers compared to the other synthesis method. Mechanical attrition methods lead to higher production rates (tons of nanomaterials can be produced in an hour) and widely used in industrial production like metal, clay, and coal powders [22–28] .
