Grinding of clinker is the last and most energyconsuming stage of the cement manufacturing process drawing on average 40 of the total energy required to produce one ton of cement During this stage the clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such.
Wet Process and Dry Process Wet Process The wet process of cement manufacturing refers to grinding raw material into slurry after mixing with water and then feeding them into the wet process kiln for drying and calcination and finally forming clinker.
Cement mills are the biggest consumers of electrical energy Good grinding organization and intense monitoring can keep grinding cost under control Regarding cement grinding the focus is on the following topics Different mill types Concepts for grinding plants Cogrinding Mixing Grinding process and cement quality.
The process of manufacture of cement consists of grinding the raw materials mixing them and then burning them in a kiln at a temperature of about 1300 o C to 1500 o C at which temperature the material sinters and partially fused to form nodular shaped clinker The clinker cool sinters and partially fuses to form a nodular shaped clinker.
Gypsum is interground with the clinker in order to control the setting properties of the cement Clinker grinding uses a lot of energy and the cement becomes hot this can result in the gypsum becoming dehydrated with potentially undesirable results see the link at.
In the next state of the process clinker is cooled in coolers The hot air from the coolers is returned to the preheater in order to save fuel in the overall process The clinker is then ground to produce portland cement Gypsum is added during the grinding process to control the set rate of the cement.
