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. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement

Cement Kilns: Grate Coolers

Grate coolers for use with cement kilns. The cooler at Rodmell replaced the original Edgar Allen reflex planetary cooler, and was in turn replaced in 1957 with a Fuller 633S reciprocating grate.. The buckets and paddles were very susceptible to wear, and the dead material lying on the grate surface tended to blind it.

Grate Cooler in Cement Plant Cement Clinker

The grate cooler belongs to the family of air quench cooler (AQC). The clinker fed into the grate cooler can be quenched from 1300-1400 ℃ to below 100 ℃ in just a few minutes. The grate cooler can be further divided into three types: the rotary cooler, the traveling grate cooler, and the reciprocating grate cooler.

How Does Clinker Cooler Reduce Cement

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 ...

Fan (machine) - Wikipedia

A fan is a powered machine used to create a flow of air.A fan consists of a rotating arrangement of vanes or blades, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner.Usually, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades.

GRATE COOLER - Page 1 of 1

In addition, lower grate speed has had a positive effect upon grate wear rates. High undergrate pressures and airflows adversely affect the conveying action of a reciprocating grate. High air pressures can reduce the friction between the clinker and the grate, which in turn can speed up the movement of the clinker toward the cooler discharge.
