Problems solved by technology

[0002] The powder industry is the basic raw material industry of China's national economy. Almost all modern emerging technologies and industrial development originate from the progress of powder preparation technology. Pulverization technology is an indispensable new technology for modern industrial production and scientific research. With modern engineering With the development of technology, many basic industries have put forward higher requirements for the characteristics of powder materials, such as the particle size, particle size distribution, and particle shape of processed materials should be finer and more uniform, because these characteristics of powder materials not only determine the processing of materials Performance and absorption performance, but also affect the application range and effect of materials; ball mill is an indispensable machine in crushing technology, and has been widely used in the processing of pharmaceuticals, chemicals, food, electronics, pesticides and various mineral powders. Whether the ball mill can work safely and efficiently is the key to the whole crushing process, so it is very necessary to optimize the control of the ball mill. It is necessary to accurately detect the internal load parameters of the ball mill, such as medium filling rate, material-to-ball ratio and abrasive concentration. The most important measure to realize the optimal control of the ball mill. Realizing the optimal control of the ball mill can improve the working efficiency of the ball mill and the quality of the ball mill, and can prolong the service life of the ball mill and reduce maintenance costs. However, when the existing ball mill is working, the ball mill cannot be detected. Therefore, when the ball mill adds medium, feed and water, it is generally added regularly and quantitatively, which cannot achieve the goal of optimal control of the ball mill.
