Cement – Analysis - IEA

The direct CO 2 intensity of cement production increased about 1.5% per year during 2015-2021. In contrast, 3% annual declines to 2030 are necessary to get on track with the Net Zero Emissions by 2050 Scenario. Sharper focus is needed in two key areas: reducing the clinker-to-cement ratio (including through greater uptake of blended cements) and deploying innovative technologies, such as ...

Cement – Analysis - IEA

Clinker is the main ingredient in cement, and the amount used is directly proportional to the CO 2 emissions generated in cement manufacturing, due to both the combustion of fuels and the decomposition of limestone in the clinker production process.


Earlier we considered a mixture of which materials is used in cement production. The base of this mixture is a clinker. In this article, we will consider the composition of clinker and its impact on grinding balls deterioration in milling process. Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about ...

Cement clinker - Wikipedia

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.


After cooling, the clinker can be stored in the clinker dome, silos, bins, or outside in storage piles. The material handling equipment used to transport clinker from the clinker coolers to storage and then to the finish mill is similar to that used to transport raw materials (e.g. belt conveyors, deep bucket conveyors, and bucket elevators).

industry. 1. Introduction and Background ... The addition of troctolite in the quantity of 25 % to Portland cement clinker at the grinding stage allows to intensify the process of hydration of the ground to the specific surface area of 450 m2/kg of Portland cement. As a result, calcium, magnesium, iron hydrosilicates are formed as well as their ...

The Cement Production Process

Finish Milling of Clinker. Finish milling is the grinding of clinker to produce a fine grey powder. Gypsum (CaSO 4) is blended with the ground clinker, along with other materials, to produce finished cement. The gypsum controls the rate of hydration of the cement in the cement-setting process.

Cement Production Process - AGICO

Clinker production: The diameter of the clinker ball must between 0.32 and 5.0cm. There are three steps of the high-temperature system: Drying or preheating, calcining, and sintering. The calcining is the core part of the clinker production; the raw meal is weighed and sent into preheater and cement kiln to process clinker.

2006). The clinker is then cooled and is mixed with a small amount of gypsum, and other materials, such as slag. The mixture, whose composition is varied depending on the type of portland cement that needs to be produced, is then ground together in a fine-grinding mill to make portland cement.

Cement Notes | Class 12 Applied Chemistry Unit 19 | NEB Notes

Then the clinkers are grinded into powder in a ball mill along with 2 – 3 % powder gypsum (decrease the setting time) to produce cement. The grinded cement is store in the silos, from which it is marketed by packing in 50 kg bags. Cement industry in Nepal The use of cement in Nepal begins from 1950's but supply of cement was diversified in 1965.

Gray Portland Cement and Cement Clinker From Japan: Continuation of ...

Cement clinker, an intermediate material produced when manufacturing cement, has no use other than grinding into finished cement. Microfine cement was specifically excluded from the Order. Cement is currently classifiable under the Harmonized Tariff Schedule of the United States (HTSUS) subheading 2523.29 and cement clinker is currently ...

Section snippets Experimental work. The same lots of Portland cement clinker and natural gypsum (CaSO 4.2H 2 O) were used in this industrial-plant-scale experimental work to eliminate the potential effects of variations in the feed to the grinding systems. Chemical compositions of the clinker and the gypsum, measured by X-ray fluorescence analysis, are given in Table 1.
