ZHANG YARU et al: AN INTELLIGENT CONTROL SYSTEM FOR COMPLEX GRINDING PROCESSES

The beneficiation process contains a number of links which are closely related to all aspects of the quality of products in a process which has a direct impact on the next one, thus influencing the product quality of all processes. Grinding operations form a critical stage in the middle position of the beneficiation process and is the most important part. Grinding operations here refers to ore processing to meet the requirements of smaller particles,the purpose is to make all or most of the ore to reach monomer separation, and flotation to provide a stable product for the next job with strict overflow granularity. But grinding processes involve complex, large equipment, not easily manipulated, influenced by many factors, and coupled with the objective it is clear the grinding operation is difficult to achieve the desired working condition. Therefore, automation control of the grinding and classification operations become an important research topic. In this paper, the background to grinding and classification control is given first, followed by an analysis of the grinding process details to describe the basis of priorities, difficulties and complexities of control and the proposed programs to use intelligent fuzzy logic as the core technology.
