Ball mills, in essence, are a highspeed 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 muchreduced efficiency. Ball mill mixers are generally used for smallscale RD laboratories, be it in an academic or industrial setting.
