2017-2-20  The feed to a dry grinding system must be dried if the moisture content is high. A ball mill is more sensitive to clogging than a rod mill. An air stream through the mill can reduce the moisture content and thus make a dry grinding possible in certain applications. A rod mill has a reduced capacity when used for dry grinding.

Wet Ball Mill for Metal Ores and Non ball mills

Wet ball mill is a kind of equipment which uses grinding medium and a certain amount of liquid (water or anhydrous ethanol) to grind materials. Unlike dry ball mill, wet ball mill adopts the wet grinding method. The characteristic of wet grinding is that the material needs to be soaked in the liquid for grinding. This method can effectively reduce the chance of the material properties changing

Fine grinding of wood Overview from wood

2018-6-1  Fine grinding mills can be categorized into five groups : impact mills, ball media mills, air jet mills, roller mills, and those of some other type, including disc mills. Impact mills and air jet mills are based on single impacts, as presented in Fig. 4a, while ball media mills utilize double impacts between metal surfaces (Fig. 4b).

As the moisture content of wood changes, it's shape usually changes as well. The wood is perfectly happy with this fact, we are often not (I recommend Bruce Hoadley's 'Understanding Wood' for a great technical explanation of all this). When it comes to wooden balls, moisture changes quickly change a round ball into a not-so-round ball.
