Composition, Types & Uses, Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln ,.
Process for the production of portland type cement clinker ,, An improved process for producing portland and portland type cement clinker wherein argillaceous and calcareous type materials are ground and blended to form a generally homogeneous mixture and subsequently burned in a kiln at a temperature in the range of about 1200° C to about 1500° C to form cement clinker, the improvement comprising incorporating into the mixture a fluorine containing ,Cement Manufacturing Process: What is Cement made of, and, In the wet process, however, these materials are supplied into the kiln in the form of an intimate mixture with water called SLURRY 1 Dry Process of Manufacture of Cement Following are the main steps in this process of cement manufacturing: i Treatment Of Raw Materials ii Burning of the Dry Mix iii Grinding of the Clinker ivParametric Studies of Cement Production Processes, Moreover, the clinker burning process, which has a decisive influence on energy consumption and the cost of cement production, involves the combustion reaction of fossil fuel and a complex heat exchange between solids from raw materials and hot combustion gases [2, 3] It also involves mixing, as well as separation of solid and fluids at ,Energy and Cost Analysis of Cement Production Using the ,, 40% more cost intensive in cement production than the dry process while at the same time it is cost effective to run production on energy through gas powered plant than the national gr Keywords: Wet Process; Dry Process; Cement; Crushing; Milling; Nigeria 1 Introduction Cement and/or clinker (cement primary input) is a com-Cement, Cement - Cement - Extraction and processing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of blasting when necessary Some deposits are mined by underground methods Softer rocks such as chalk and clay can be dug directly by excavators.
