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.

PROCEDURE. Kept 100 gm of rice and charge it to series of sieves to get pregrinding size distribution. Continuous sieving for 10 minutes. Weigh the mass of rice retained on each sieve. Load the rice into ball mill along with metal balls. Run the ball mill for 30 minutes at a speed of 1 rpm. After 30 minutes take out rice powder from the ball mill.
