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.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and …
