A method of developing intelligent grading controller for grinding balls

Abstract

The invention discloses a method for developing an intelligent grading controller for grinding balls, which comprises the steps of rationally selecting the types and specifications of ball mills; determining the dynamic ball supplementary parameter engineering model and programming it, and inputting storage model programs, computing controllers, Known conditions and parameters; design the main and auxiliary control circuits and components, and form the internal and external structure of the developed intelligent grinding ball grading controller; verify and improve the on-site operation performance of the developed grinding ball intelligent grading controller . The present invention is developed through the synthesis of many factors, the mathematical model created through long-term research and development as the theoretical basis, and the programming and setting of electrical and instrumentation devices. It will enable the operator of each ball mill to use the ball intelligent grading controller to achieve a scientific and maximum application of the balls in the ball mill, thereby achieving maximum energy saving and saving indicators of cost.

Description

technical field [0001] The invention relates to the field of grinding balls, in particular to a method for developing an intelligent grading controller for grinding balls. Background technique [0002] The market size of China's wear-resistant materials industry has grown rapidly, and the overall manufacturing level has continued to improve. With the steady development of the national economy, the demand for wear-resistant ball segments in my country's thermal power generation, metallurgical mines, building materials, cement and other fields has also maintained a steady growth trend. Only the domestic demand for wear-resistant ball segments reached 2.0874 million tons in 2015. The table lists the growth of domestic demand for such products from 2010 to 2015: [0003] 2010-2015 domestic market demand for wear-resistant casting grinding balls (10,000 tons) [0004] [0005] According to incomplete statistics, in recent years, my country's annual export volume of various ty...

Problems solved by technology

[0008] 2. Orthogonal experiment method (experiment period, high cost, and cannot handle large samples);

[0011] In foreign countries, in recent years, in the field of grinding ball manufacturing and use, we have begun to explore the third-level and fourth-level scientific research methods and use related technical means and tools to formulate and improve the process, and the manufacturing, use and monitoring reflect the "essence" of the process. Beautiful installation, but good and bad, progress is slow

[0012] In China, it is still in the second stage of scientific research and production application using the orthogonal experiment method, resulting in a large number of dynamic change factors that cannot be effectively controlled and predicted, and the long-term waste and efficiency of product manufacturing and product use. The problem of low cost and high cost has not been solved; the rapid development of information technology, automation and intelligent technology cannot be effectively used to accelerate technological progress in this field, and the pressure to play a leading role in science and technology is increasing

For a long time, in order to extend the service life of grinding balls, people have independently carried out the improvement of production and manufacturing experience and the improvement of the experience of using grinding balls in the two fields of grinding ball manufacturing and ball mill use. Although it is effective, the effect is It is not obvious, so that it causes great energy consumption, great environmental pollution and high cost, and lacks the competitiveness of products
