Now that we have a basic understanding of the industrial milling process, let's examine the difference between wet milling and dry milling. Dry milling typically uses particle-on-particle contact to reduce materials' size, while wet milling involves dispersing the material in a liquid and using solid, grinding elements to reduce size.
Ball mills cab be used equally well for wet or dry grinding. In the case of wet grinding the particles are also dispersed in the liquid medium. For temperature sensitive products, ball mills can be fully jacketed to maintain temperatures of the product. Ball mills scale up well and in fact improve in performed with increasing size.
