Chemical Mixing Methods

A ball mill mixer is less commonly found in a laboratory, but can be useful for mixing, homogenisation, cell disruption and DNA recovery. 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 much ...

The ball mills usually operate at 65 % to 75 % of the critical speed. This will lead to less efficiency in grinding process so it must be avoided. The efficiency of the ball mill also depends on the type of grinding balls that has been used. For this experiment, we only use one type of ball which is stainless steel grinding balls.
