Ball mill diameter, media size and mill revolutions per minute (rpm) control the process of powder mixing and particle size reduction (Upadhyaya, 1998). For given mill size and media, too low an rpm extends the process time, whereas too high an rpm leads to poor cascading of media, leading to inefficient particle size reduction.
