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.
Ball mills have the following advantages: • Universality and high capacity. • Permanence of a prescribed milling fineness by certain capacity over long periods of time (with periodical addition of balls for compensation of their wear). • Reliability and safety, simplicity of servicing.
Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
