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. More efficient classification is possible although due to high …

The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.

The grinding process requires energy, which reduces the eco-efficiency of the products. However, grinding is also a process in cement production, whose impacts add to the other intrinsic impacts not observed in the production of the proposed SCMs (e.g., carbon dioxide emissions from limestone decarbonation).

A coarser CII charge wil have lower grinding efficiency and require a higher design circulation factor. This will give a coarser product at the mill outlet and thus reduce dry coating. The balance between lower grinding efficiency and reduced coating will depend both on the material and the Length/Diameter ratio of the mill.
