The rotary kiln requires no pregrinding before being fed to the kiln and it deals better with higher moisture contents.Its disadvantages include more limited alternative fuel usage, lower temperatures from secondary air for drying raw materials and grinding after calcination.

The rotary kiln WTE system was conceived to address the following criteria: (1) to accept and process mixed, unsorted municipal waste materials, (2) to minimize process energy required through careful heat management and use of hydraulics, and (3) to integrate into contingency utility systems by using standard diesel generators.

Therefore, the wet method rotary kiln needs to evaporate additional material moisture, about 30% to 40%, which consumes more heat and energy.However, due to the homogeneous composition of the slurry raw meal, the clinker calcined in the wet method rotary kiln usually has high quality, high strength grade and less dust pollution.
