Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills. Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter grinding in mills.Clinker size and cement grinding. Clinker size is important for the optimization of cement grinding, and is also an indicator of cement quality. Having a high percentage of coarse clinker can be difficult to grind. However, having a high percentage of fine clinker can also be hard to grind and have a negative impact on cement performance.

Apr 22, 2019 2.2 Types of vitrified bond. There are many classification principles for the vitrified bond, mainly introducing the following 2.2.1 There are fused bond, sintered bond, semi fused (semi sintered)bond according to the relationship between the firing temperature of the grinding wheel and the refractoriness of the bond.Grindability and the energy consumption in clinker grinding are influenced by a number of factors as well. If it is defined as the rate of production of fine material for a given energy expenditure, then it is reasonably well accepted that grindability increases with porosity and alite content (3CaO SiO 2 or C 3 S) [1, 2] and decreases.
