Abstract:

In order to overcome the dificulty in the estimation of material amount and the parameter identification ofthe“equal mass equal energy”model proposed in the project of lithopone rotary kiln control,a new method of calculating material amount and identifying parameters is put forward based on the analyses of a large number of historical data and manual experience of workers.In the utilization of this method.the control of material amount iS brought into the control of ACC(Ability of Clearing Color),and the ACC estimated by the workers are used as the basis of the parameter identification.Moreover,the process of parameter identification is presented in detail,and the control effect is finally discussed.The proposed method is successfully applied、to the control of rotary kiln,with the yields and ACC of lithopone improved.

Key words: lithopone, rotary kiln, ability of clearing color, control model, param eter identification, equal energy
