The main power consumption of a clinker cooler is its cooling fans. It usually takes 1.9-2.3 m 3 under standard conditions to cool 1 kg clinker from 1400 ℃ to 65 ℃, and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to 1.7 m 3, the air consumption efficiency will be 15% lower than that of other cement ...
A method of cooling cement clinker produced in a rotary kiln, which comprises cooling the clinker discharged from the kiln, returning a portion of the cooled clinker to the kiln at a point beyond the clinkering zone to be mixed with the hot clinker leaving the zone and regulating the amount of the cooled clinker returned to insure that it will effect rapid cooling of the hot clinker to a ...

01-02-2001· 1. Introduction. Portland cement clinker is typically composed of 50–75% alite (C 3 S), 10–20% belite (C 2 S), 5–10% aluminate (C 3 A), and about 10% ferrite (C 4 AF). However, incorrect operation would not only lead to the generation of some unexpected phases, which are harmful to the clinker performance, but also exert a significant influence on the microscopic textures and the crystal ...

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.
In the calcination process of cement clinker, preheating, calcining, and cooling are three inseparable process links. As the supporting equipment of cement rotary kiln, clinker cooler (also called cement cooler) is a kind of heat exchange device that transfers heat from high-temperature clinker to low-temperature gas.It plays an important role in the cement clinker production process and ...
