Abstract The three times of clinker nodulation in cement kiln during collaborative treatment of hazardous solid waste was analyzed, the chemical composition and physical properties of clinker ball were tested, and the effects of chemical composition of raw material and clinker in kiln, control of raw material decomposition rate, chemical composition of hazardous solid waste and trace heavy metal content of cooperative treatment and addition of calcium fluoride sludge on clinker calcining process were analyzed. To solve the problem, it was optimized by stabilizing the chemical composition of raw material and clinker, appropriately reducing the content of Fe2O3 of raw material and the decomposition rate of raw material in hot kiln, strengthening the control of harmful components such as Cl-, R2O, etc. At the same time, the influence of adding dangerous solid waste to improve the burnability of raw material was fully considered in the process of mixing and calcination. At last, it effectively solved the problem of frequent clinker agglomeration in the cooperative disposal process of cement kiln.
