energy consumption at cement clinker mill

Clinker is transferred to the finishing mill, where it is ground and mixed with gypsum to produce the final product. While cement production expends energy at every step, the kiln is one of the most difficult to optimize. Modern cement plants typically use dry rotary kilns with calciners.
