Raw mills for all requirements | Gebr. Pfeiffer

Depending on its deposit and composition, the cement raw material may contain a more or less big portion of water. Especially with high feed moistures, drying is of particular importance because the existing surface moisture has to be evaporated almost down to zero in the raw mill. The thermal energy required for this purpose is made available in the form of hot gases which are drawn through ...

Portland Cement Manufacturing

· Cement raw materials are received with an initial moisture content varying from 1 to more than 50 percent. If the facility uses dry process kilns, this moisture is usually reduced to less than 1 percent before or during grinding. Drying alone can be accomplished in impact dryers, drum dryers, paddleequipped rapid dryers, air separators, or autogenous mills. However, drying can also be ...
