Cement. gypsum and pozzolana are going to be used for final cement grinding together with clinker produced from kiln. in this unit there are three crushers few meters away from the quarry; two limestoneshale crushers (one for line 1 and one for line2) and one additivecorrective crushers common for both lines.

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.
