Types of Cement Processes • Wet Process. • Dry Process - 74% of cement produced. • Preheater/Precalciner Process. 16. Evolution of the cement Process • Wet process easiest to control chemistry & better for moist raw materials. • Wet process high fuel requirements - fuel needed to evaporate 30+% slurry water. • Dry process kilns less fuel requirements • Preheater/Precalciner …

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. It has to be long because a lot of water has to be evaporated and the process of heat ...

Cement - Fuels & Technologies - IEA

Globally, the energy intensities of thermal energy and electricity have continued to gradually decline as dry-process kilns replace wet-process kilns, and as more efficient grinding equipment is deployed. Fossil fuels continue to provide the majority of energy in the cement sector, with alternative fuels such as biomass and waste accounting for very small portions.

Use of Alternative Fuels in Cement Manufacture: Analysis ...

Wet process rotary kilns are more energy-intensive and have been rapidly phased out over the past few decades in almost all industrialized countries except the US and the former Soviet Union. In comparison to vertical shaft kilns, rotary kilns consist of a longer and wider drum oriented horizontally and at a slight incline on bearings, with raw material entering at the higher end and traveling ...
