The most notable type of cement produced is Portland cement, but certain active ingredients of chemical admixtures may be added to clinker to produce other types of cement, such as: ground granulated blast furnace slag cement
The addition of oxygen to the air drafting the burners—so-called oxygen enrichment—has been practiced in cement kilns since the early 1960s and results in increased clinker production and reduced fuel consumption. Fuel consumption is reduced in part because nitrogen in the air does not need to be heated up to combustion temperature.
Slag, a waste product of steel manufacturing, and fly ash, arising from coal fired power generation, have cementitious properties and can be used to supplement clinker in cement. The proportion of clinker replaced with slag or fly ash is referred to as the Mineral Addition Rate.
Portland cement clinker overview The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail sketch.
In the rotary kiln itself, a temperature of approx. 1450 ° C causes sintering a chemical/mineralogical process, during which the cement clinker is formed. The clinker formed is then cooled in clinker cooler.
4. Cement production. The clinker is processed into different types of cement. Apart from gypsum and clinker, various additives such as slag sand, trass and fly ash are also ground up with them, depending on the type of cement required. The MULTIDOS® weighfeeder feeds material into the mill, similar to the earlier feeding into the raw mill.

Dangote Cement aims to serve the whole of West Africa with 4Mt/yr of clinker exports from the terminal.
Clinker cooler is also called cement cooler, which set behind the cement kiln for clinker cooling. In cement plants, we usually adopt the rotary cooler and grate cooler for daily production. Inside the cooler, hot 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
The cement clinker calcination is an important step in the cement production process. It mainly occurs in cement kiln and can be roughly divided into six reaction stages, namely drying, preheating,

(India) — The country’s cement industry has been hit by short supply of clinker, the principal raw material, due to its price hike in international market, sending yet another blow to the real estate sector, now experiencing an unprecedented slump.The price hike of clinker
Feb 21, 2019· Clinker (in cement industry) is transitional product in cement production. Upon heating mixture obtained from limestone (about 75%) and clay (about 25%) partial melting occurs and clinker granules are formed. Clinker and gypsum (about 5 %) are mixed and finely milled to obtain cement. Gypsum control the setting properties of the cement.
May 19, 2020· Estonia: Cement producers achieved a total output of 129,000t of cement in the first half of 2020, down by 31% year on year from 187,000t in the first half of 2019. Eesti Statistika has reported that the sharpest decline was in June 2020, by 41% year-on-year to 25,800t from 43,700t. Estonian clinker production ended on 27 March 2020 with the closure of Kunda Nordic Cement

The incentive to ‘reduce the clinker factor’ in cement products is two-fold. The primary motivation is to reduce the energy consumption and CO 2 emissions associated with cement clinker production in rotary kilns. It is generally accepted that the production of 1 t of ordinary Portland cement
Cement is a binder used for construction that sets, hardens and adheres to other materials. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. The cement industry is the building block of the construction industry. Few construction projects can take place without utilizing cement
