Cast grinding ball grading mathematical modeling method based on visual platform

Abstract

The invention discloses a cast grinding ball grading mathematical modeling method based on a visual platform. According to the mathematical modeling method, on the basis of an optimal grading scheme of four kinds of grinding balls with different diameters, a most economical grinding ball material and an optimal loading capacity of the grinding balls, the optimal grading scheme of the grinding balls with the different diameters is adopted for establishing a dynamic ball supplementing parameter engineering model, and ball supplementation is carried out on a mill according to a ball supplementing scheme corresponding to the dynamic ball supplementing parameter engineering model so that dynamic grading of the grinding balls in the mill can keep the same level. A visual method, the optimal grading scheme of the grinding balls and the high-precision dynamic ball supplementing parameter engineering model are applied in combination with a practical site situation for establishing a grinding ball loading and supplementing system, it is ensured that grading of the grinding balls can be stably and reliably at the optimal grading level of the engineering state in the running process of the ball mill, and the bottleneck that application and popularization cannot be realized due to the fact that the energy conservation, consumption reduction and production cost reduction effects achieved by the application of the grinding balls are unremarkable and unstable is broken through.

Description

technical field [0001] The invention relates to the field of grinding balls, in particular to a visual platform-based mathematical modeling method for gradation of casting 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 volu...

Problems solved by technology

[0008] 2. Orthogonal test method (test period, high cost, and unable to 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

In China, it is still in the second stage of scientific research and production application using the orthogonal test 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

The installation of grinding balls in traditional coal mills is mainly based on the current of the coal mill, and the method of regularly adding large-diameter grinding balls (φ60mm) is adopted, which may easily lead to an unreasonable proportion of grinding balls with different diameters inside the coal mill cylinder, causing damage to the coal. The crushing force of lumps and coal particles is sufficient, but the grinding force is insufficient; under this working condition, the dynamic distribution of grinding balls with different diameters is not conducive to efficient pulverization; Increased unit consumption
