How to choose between sand mill and ball mill?

The results show that the sand mill is far superior to the ball mill in terms of grinding efficiency and preparation cost. The sand mill can produce a powder with an average particle size of less than 0.5μm, which is far smaller than the particle size of the product obtained by the ball milling mechanism. Next, we use an experiment to compare ...
