Cement clinker is the semimanufactured material which needs to be ground into powder to make ordinary cement it may present fewer problems than the carriage of cement its biggest advantage is that it does not harden when in contact with water reducing the damage it can cause to the vessel.Inquiry Online
Apr 03 2020 cement production begins with limestone a sedimentary rockOnce quarried it is mixed with a silica source such as industrial byproducts slag or fly ash and gets fired in a kiln at 2700 degrees fahrenheitWhat comes out of the kiln is called clinker.
Apr 07 2020 the final product – cement – is obtained by grinding the clinker to a fine powder in a cement mill together with some 34 of gypsumThe gypsum is a necessary additive in order to retard the setting time of cement.

Cement manufacturing the raw materials required to manufacture the clinker are limestone bauxite ore iron ore and sand.
Clinker and gypsum being mixed together in predetermined proportions are fed to the grinding mills.
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement productsThe lumps or nodules of clinker are usually of diameter 325 mm and dark grey in color.
Clinker is the basic raw material used in the production of all types of cement and the one that bestows upon cement its hydraulic properties.
Fast cooling of clinker is advantageous it makes for more hydraulicallyreactive silicates and lots of small intergrown aluminate and ferrite crystalsSlow cooling gives less hydraulicallyreactive silicates and produces coarse crystals of aluminate and ferrite.
In portland cement manufacturing process the quality of cement clinker directly affects the quality of the finished product cementThe following are several important factors affecting the cement clinker quality.
In the cementmanufacturing process raw materials are heated to high temperatures in a kiln in a fuelintensive process known as pyroprocessing exhibit 2.
It has a production capacity of 1700 tons of clinker and 4000 tons of cementThe clinker produced is not sufficient to make all the required cement and therefore the plant import some clinker to meet the deficit.
More than 50 per cent of cement sector emissions are intrinsically linked to the process for producing clinker one of the main ingredients in cement.
Oct 01 2020 this research focused the role to study the effects and ways to control the chemical composition of clinker for better cement production.
