Blending expert system for raw mix slurry in production of alumina with sintering process

Based on the blending theory of raw mix slurry in production of alumina with sintering and on the knowledge from experts, the predictive model of quality of raw mix slurry was presented, and a blending expert system adapting productive features of raw mix slurry in production of alumina with sintering was developed. According to the actual production and blending theory, the knowledge expression form of production rule and the classified principle of rule collection were used, and a blending expert knowledge base of raw mix slurry was designed. Then the inference engine was realized through the hybrid of heuristic search among the rule collections forward chaining in the interior rule collection and Hash algorithm between the precondition and the conclusion of the rule, which implements the match computation. The blending expert system was put in plements t slurry and to service in an alumina smeltery. The actual running results show that the system implements the computation of blending ratio fast and efficiently, improves the quality of raw mix slurry and stabilizes industrial production.
