A dry process kiln might be only 70m long and 6m wide but produce a similar quantity of clinker (usually measured in tonnes per day) as a wet process kiln of the same diameter but 200m in length.

Cement kiln

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant. As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been th

The use of the dry process for cement production has increased significantly in the last couple of decades (Figure 1), partially due to the lower fuel requirements for the dry process (discussed further below). In 1975, dry kilns comprised 38% of all kilns, whereas in 2001, dry kilns

Cement Manufacturing Process: How the Cement is Made?

All the cement plants set up after 1980 use the dry process for the manufacture of cement. In this process, the calcareous materials such as limestone are crushed and stored in silos or storage tanks. The argillaceous material such as clay is thoroughly mixed with water in a container known as the wash mill. This washed clay is stored in basins.

CEMENT MANUFACTURING PROCESS AND ITS SELECTION:

Heat consumption foe wet process is higher (1350- 1500 kcal / kg clinker) whereas for the dry process it may vary from 720- 1100 kcal / kg clinker depending upon the type of kiln being used. There is a higher wear rate of equipment kiln chains, liner plates etc. in the wet process. Semi wet Process

Additionally, to evaporate the water contained in the slurry, a wet kiln consumes nearly 33 percent more kiln energy when compared to a dry kiln. Wet-process kilns tend to be older operations as compared to dry-processes where raw materials are fed into the process as a dry powder.

Fundamental Aspects of Kiln Drying Lumber Oklahoma State

Kiln schedules are used to determine the temperature and relative humidity needed in the kiln to dry specific wood products at a satisfactory rate without causing objectionable drying defects. A typical kiln schedule is a series of temperatures and relative humidities, which are applied at various stages of drying as can be seen in Table 1.
