The cement clinker is ground as finished cement, in a vertical roller mill for cement or in ball mills similar to those normally used for grinding hard raw materials in dry and semi-dry processes. However, the cement clinker is more difficult to grind than raw materials and must also be finer ground.
Dry ball mills offer extensive application prospects within the mineral processing process, promising enhanced production efficiency, cost reduction, and advancements in environmental protection and energy conservation. This versatile milling method eliminates the need for liquid additives, resulting in finely processed materials …
