Comprehensive understanding of grinding aids

The milling media (balls) in Figure 1, which are coated by ground particles, represent a state of minimum energy of a system without grinding aids. Likewise the clean milling media in Figure 2 represent a state of minimum energy of a system with grinding aids. Presence of grinding aid leads to a different minimum energy state [3].

Grinding vials differentiation and sample .

Grinding media must be able to move freely to impact the sample; therefore, homogenization vessels must not be overfilled with a combination of sample, beads and/or buffer. Generally, the samples should take up no more than a sixth of the volume of the vessel, and grinding media should take up no more than a third of the volume of the vessel.
