Wet Versus Dry Primary Grinding. From the standpoint of operating costs, it is to be expected that liner wear, and, where a small ball charge is used, ball wear would be higher in wet grinding than in dry grinding.

Ball Mills or Rod Mills in a complete range of sizes up to 10′ diameter x 20′ long, offer features of operation and convertibility to meet your exact needs. They may be used for pulverizing and either wet or dry grinding systems. Mills are available in both light-duty and heavy-duty construction to meet your specific requirements.
Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. Wet Ball Milling Vs Dry Ball Milling
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 …
