Cell disruption: Ball mills are used to disrupt cells and release intracellular materials for downstream analysis. This technique is widely used in biotechnology and biochemistry for the isolation of proteins, DNA, and other biomolecules.
Bead milling or bead homogenization is a mechanical cell disruption process with some degree of complexity. Through this technique, cell disruption is induced through shear forces produced during the rotary movement of the cells and the beads and cell grinding between beads [12] (Figure1). Beadcell collisions are also purportedly implicated

Beadbased homogenization uses plastic or metal beads combined with highspeed shaking to create shearing forces. This technique is wellsuited to whole animal, insect (, Drosophila melanogaster) or plant specimens, which requires disruption of sturdy cell drawback of beadbased disruption is that it requires the proper selection of bead material and diameter.
High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.
