Grindingefficiency is the energy utilised to create specific surface ofmaterialhaving same chemical/mineralogicalcomposition. This can be expressed as: Eu = (Specific surface created/specific energy used). Energy utilisation in VRMgrindingis better than ball mill technology.
Raw material preparationaims to preare a mixture that has the right chemicalcompositionand particle size necessary for the clinker production. For plants that receive their rawmaterialsalready crushed, this stage usually involvesgrinding(milling), classification, mixing and storage. Ball mills, tube mills, vertical or horizontal roller mills are commonly used forgrinding.
