Clinker Cooler

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 Get price

Cement 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 Get price

Clinkerization

2020/05/16Rapid cooling of clinker can mitigate the expansion problems, however higher MgO causes ball formation in kiln, increases melt phase etc. and therefore, can disturb kiln operation. Alkalies A part of alkalies Na 2 O and K 2 O combines chemically with clinker minerals, while as the major part remains as water soluble and affects adversely cement strength (28 Day Strength).Get price

Cement kiln

In the cooler the air is heated by the cooling clinker, so that it may be 400 to 800 C before it enters the kiln, thus causing intense and rapid combustion of the fuel. The earliest successful rotary kilns were developed in Pennsylvania around 1890, based on a design by Frederick Ransome, [4] and were about 1.5 m in diameter and 15 m in length.Get price
