Depending on the process type, kilns have length-to-diameter ratios in the range of 15:1 to 40:1. While some wet process kilns may be as long as 210 m (700 ft), many wet process kilns and all dry process kilns are shorter. Wet process and
Read MoreWet process cement manufacturing method can be used to produce various types of Portland cement, such as ordinary Portland cement, white Portland cement, oil well cement, etc. It can help your cement plant to achieve high quality and
Read MoreCement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

The slurry has good fluidity, good homogeneity, and the quality of the clinker is improved. In addition, the energy consumption of raw material grinding in wet
Read MoreRaw Materials of Cement. Most important raw materials (what is cement made of) required in the manufacture of Portland Cement are: Limestone, Clay, Gypsum, Fuel, and Water (in wet method). 1. Limestones: These are sedimentary, calcium carbonate rocks (CaC0 3 ). Most commonly they contain a small amount of magnesium carbonate also.
