For example 0.1 - 0.5 g glycol (ethylene glycol) per 100 g of sample = 5 - 25 drops cause (with an already existing adhesion) a good flow characteristic; the sample remains dry, the charge / adhesion powers are reduced and the grinding period can be substantially increased.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

The most obvious difference is the use of water while grinding and the non-use of water, that is where the wet and dry name comes from. The wet concrete grinding process. The concrete wet process uses water, which is relatively accessible. The water cools the diamond tooling by acting as a lubricant to reduce friction.
