Manufacturing - the cement kiln - Understanding Cement

Wet process kilns. The original rotary cement kilns were called 'wet process' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.

In addition, the raw material slurry can also be dehydrated into raw material blocks and put into the kiln to calcine clinker. This method is called the semi-wet process, which still belongs to the cement wet process production. Advantages: the wet process of cement production has the characteristics of simple operation, low dust and easy conveying. Because the slurry has fluidity so that its homogeneity is good and the quality of clinker is improved.
