Grinding, for example in a ball, rod, or hammer mill, is necessary if the gypsum is to be used for high quality plasterwork or for moulding, medical, or industrial applications. Unlike with other cements, such as lime and Ordinary Portland Cement, special mills for mineral grinding may not be required and the relatively soft gypsum could be ...
Gypsum. Gypsum added to the clinker is largely dehydrated by the cement-grinding process, to form the rapidly soluble hemihydrate. From Leas Chemistry of Cement and
Wet grinding of gypsum is an economical method of producing a powder having average particle sizes less than 10 microns. A slurry of gypsum in water flows through a comminution or grinding device, such as a ball mill, and can be recycled through the comminution device as much as necessary to obtain the desired particle size range.
The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4 and in case of Quick setting cement it can be reduced up to 2.5. Role of Gypsum in Cement The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water.
