The cement production is one of the most energy consuming processes, typically accounting for 50 to 60% of the production costs. However, there are several ways of heat recovery opportunities to achieve better energetic and exergetic efficiencies for the whole system. In this paper, energetic and exergetic analyses of an existing rotary kiln ...
For this purpose, influences of 250, 350 and 450 g/t of dosages of an amin-based commercial GA on the cement grinding circuit was compared with the condition in which GA was not used. The effects of GA dosage on the ball mill and air classifier were examined in detail considering the change in the residence time of the material.
Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set. Water spray is controlled with mill outlet gas or material temperature. A hardware interlock is recommended with mill main drive to avoid accidental spray in …
