Our 2050 Roadmap The 5C Approach Clinker Cembureau

Clinker is produced by heating crushed limestone and a mix of other materials (clay and sand) to 1450 C in a rotary kiln. Clinker is later ground down to a fine powder and mixed with gypsum and other ingredients to make cement. The rotary kiln is the heart of the manufacturing process where raw materials are heated up and decarbonisation of ...

US5572938A Oxygen lancing for production of cement

US5572938A Oxygen lancing for production of cement

Oxygen is lanced into the main combustion reaction of a cement kiln to increase heat transfer to the clinker bed and to increase clinker production. Oxygen is separately lanced along the floor, i.e. the lowest wall of the kiln, to delay mixing with the flame to provide deep staging. The deeply staged oxygen flow is adjusted frequently to control emissions and stabilize the burning zone

Cement kiln Wikipedia

Cement kiln Wikipedia

Rotary kilns of the cement industry and classic incineration plants mainly differ in terms of the combustion conditions prevailing during clinker burning. Kiln feed and rotary kiln exhaust gases are conveyed in counter-flow and mixed thoroughly. Thus, temperature distribution and residence time in rotary kilns afford particularly favourable ...

What is Cement Clinker Composition Types Uses Civil

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 1400C-1500C in the rotary kiln. ...
