High-energy ball milling is a type of mechanical grinding of materials. This process can be conducted in a dry (without solvents) or wet (with solvents) fashion. Laboratory-scale ball milling (5–100 mL scale) is a batch process, whereas industrial ball mills can be operated in a continuous mode, thus offering a very high synthesis throughput.
For the glass processing, a ball mill comprises of a rotating ceramic-lined drum, with several other durable material inside the drum forming the grinding medium, typically – alumina or zirconia etc. . In the process, the glass is added to the drum and then the drum rotates which causing continuous attrition and impact between the balls and …
