Chat OnlineThe final step of the cement manufacturing process is the milling. In this step the clinker is ground together with additives in a cement mill. All cement types contain around 4–5 gypsum to control the setting time of the product. Chemical compounds are used to improve the particle comminution during the grinding of materials (grinding aids).
Chat OnlineAs grinding aids affect both the adsorption layer as well as the grinding mechanism inside the mill (see Section 5.1) particle morphology and surface roughness are possibly changed by the grinding application. Furthermore the layer of the adsorbed molecules does not only affect the surface roughness but also the distance between two particles.
