Uniform kiln feed size helps reduce tendency to form kiln rings. WET VS DRY Grinding of Cement. Wet grinding is generally more efficient and permits a balanced feed direct to the grinding mill since a thorough mixing takes place during comminution. Since dust is not prevalent this hazard is eliminated and a cleaner plant results.
