Wet rawmills. Wet grinding is more efficient than dry grinding because water coats the newly formed surfaces of broken particles and prevents reagglomeration. The process of blending and homogenizing the rawmix is also much easier when it is in slurry form. The disadvantage is that the water in the resultant slurry has to be removed subsequently, and this usually requires a lot of energy. While
