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 will direct contact with the cooled air blown from the air blower to realize fast cooling.

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 1400 c-1500 c in the rotary kiln. .

Clinker is discharged red-hot from the lower end of the kiln and generally is brought down to handling temperature in various types of coolers. the heated air from the coolers is returned to the kilns, a process that saves fuel and increases burning efficiency. after the clinker is cooled, cement plants grind it and mix it with small amounts of .

Clinker produced by early static kilns was in the form of large pumice-like lumps. rotary kiln clinker on the other hand, because of the rolling action of the kiln, emerges as fairly regular roughly spherical hard nodules of diameter typically 5-50 mm, together with a certain amount of dust abraded from the nodule surfaces.. clinker minerals react with water to produce the hydrates that are .

Clinker, of which 0.46 tons are attributable to fuel combustion. combustion emissions include co2, n2o and ch4 emissions that result from the combustion of carbon-based fuels in the cement kiln and other onsite combustion equipment. the cement kiln is the most significant of these combustion units and typically is fueled with coal.

Cyclone preheater in cement plant . cyclone preheater can make full use of the heat in the kiln, reduce the heat consumption of clinker burning, reduce the floor space of the burning equipment, fully utilize the heat in the kiln, reduce the heat consumption of clinker burning, and reduce the floor space of the burning equipment.
