  • Ball Mills - an overview ScienceDirect Topics

    3.6.1.1 Ball Milling A ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.
