How to deal with material agglomeration when drying after wet-grinding by planetary ball mill?


We know wet grinding is superior to dry grinding in terms of grinding effect or grinding efficiency. But the problem is sometimes the materials will agglomerate when drying after wet-grinding.


If materials agglomeration occurs, you can use a vibration sieve .


Serious agglomeration may occur when the drying temperature is too high which high temperature will enhance the activity of the powder, leading to easy agglomeration. It may also occur when the grinding aids are not chosen properly. Different materials use different grinding aids, using water, alcohol or other solvents, which will have different results depending on the material properties.
