    Chemical Mixing Methods Azomcom

    Jun 22, 2017 Ball mills, in essence, are a high-speed shaker. If you were to take a small sample vial and shake the contents along its vertical axis then you would do the same job as a ball mill mixer, albeit with a much-reduced efficiency. Ball mill mixers are generally used for small-scale R&D laboratories, be it in an academic or industrial setting.
