Cement raw material ingredient control system and method

Abstract

Provided are a cement raw material ingredient control system and method. The cement raw material ingredient control system comprises a grinding control system, a raw material automatic sampler, an on-line analyzer and a raw material quality control system. The raw material automatic sampler is arranged at a grinding machine raw material outlet, carries out grinding powder sampling, and conveys the grinding powder sample to the on-line analyzer, component analysis is carried out, the on-line analyzer sends the analysis result of the grinding powder sample to the raw material quality control system, the raw material quality control system carries out self-adaptive adjustment of raw material ratios according to the analysis result of the grinding powder sample and a raw material object rate value, and the adjusted raw material ratio values are sent to the grinding control system. Component analysis of raw materials is carried out on the on-line analyzer, the matrix semi-tensor product theory and the fuzzy control theory are employed to carry out self-adaptive adjustment of raw material ratios according to the raw material object ratio values, therefore real-time and self-adaptive adjustment of raw materials is carried out, fluctuation of the raw material ratio value is lowered, and the raw material quality is ensured.

Description

technical field [0001] The invention relates to a cement raw meal batching system and method, in particular to a cement raw meal batching control system and method, belonging to the technical field of cement production technology. Background technique [0002] The cement production process can be briefly summarized as "two grindings and one firing", wherein "two grindings" refers to grinding raw materials into raw materials and grinding clinker into cement, and "one firing" refers to calcining raw materials to form mature cement. material. The whole process is a typical continuous process. The quality of the previous stage has an important impact on the quality of the next link, and the raw material powder into raw material is the most important link in the entire cement production. The raw material composition determines whether the three rate indicators are qualified. , is the premise to ensure the stable production of the whole cement production line. Therefore, the qual...

Problems solved by technology

Its disadvantages are: because people are prone to fatigue, the accuracy of the timing of sampling by laboratory personnel and the accuracy of laboratory operations cannot be guaranteed; secondly, the operator in the central control room adjusts based on experience rather than strict calculation, which is relatively subjective and the adjustment is difficult. The effect is difficult to guarantee; in addition, in the actual production process, in general, the raw material composition will fluctuate, sometimes the fluctuation is relatively large, and the adjustment is made according to the results of the hourly sampling laboratory, and the fluctuation of the raw material rate value will be relatively large
