Clinker replacement | Climate Technology Centre & Network
The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process. Portland cement, the most widely used cement type, contains 95% cement clinker. Large amounts of electricity are used grinding the raw materials and finished cement.

Clinker Production
Clinker cooling is the final step in clinker production. This process aims to recycle heat, preheat the secondary air, and improve the quality and grindability of the clinker. Besides, the rapid cooling of the clinker in this process is convenient for cement storage and transportation.

The Cement Manufacturing Process
Coal is used for heating the raw materials at 1450 degrees centigrade to turn into clinker. The grade of coal supplied in the cement manufacturing industry depends on the grade of limestone used in the cement manufacturing process. If the limestone used in the cement manufacturing process is of high grade then low-grade coal is used and vice versa.

Cement clinker
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

Use of high MgO limestone in Portland cement manufacturing
The limestone requirement for production of 71.28 MT of clinker during 1997-98 was 106.92 million tonnes and in the year 2013-14 it has enhanced to 300.00 MT. From an estimate it has been seen that for production of 500 MT of Clinker (as anticipated) by the end of 2020 the limestone requirement will be around 700 million tonnes.

Understanding Limestone in Cement| Concrete Construction
Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production. The resulting cement will perform at least as well as cements

What is Cement Clinker? | Datis Export Group
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.

Clinker. Clinker is the backbone of cement production. It is essentially a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. When limestone is converted to clinker, CO 2 is released (also known as process emissions). A substantial amount of heat is needed to start and sustain the chemical
