KMRI-500 grinding sorting multi-parameter dynamic control system operation

Honeywell Distributed Control System is the United States launched the latest generation of control system, the system by the controller, the operator station. Flood high-speed communication networks. Monitoring station and special interfaces and other components, using the hardware level CPU processor, data acquisition, logic control, loop control, regulation-in-one, can easily generate bar chart, trend chart. Statements and other images, its function is strong, flexible configuration. High reliability. Small and medium ideal for automated process control. 4.2PLC5/15 and ONSPEC composed of small D 【: S control system produced by the United States AB PLC5/15, with modular structure. Rejection users can configure their own needs to be thrown under the system, the 1 / O capacity of 512 points, with 8K bytes of EEPROM. Heuristics ONSPEC control software is the United States launched the industrial control software system, from 1 to 886 or PC486 and other environments run and fifty wide range of industrial machines can communicate, to achieve color graphics display, the operator trends, alarm secret files records, control functions, historical data analysis, real-time calculation and other functions, the entire system configuration 6 Ye He Mine Design and Construction 2, 1998 Yun, reliable quality. Anti-interference ability. Convenient operation and maintenance, the failure rate is low. 5 system function and performance (】) on the host computer system process loop to achieve dynamic display, real-time parameter alarms, historical data and trends in real-time data display, control, go the same way show that optimization of control parameters and settings. Warning statements and other reports and print production. (2) system to achieve the main process equipment of the chatter stopped opening sequence, with bulging belly and an empty stomach mill town of automatic protection and treatment. (3) the system can realize the sorting processing plant operating grinding the main process parameters: mill load 'grinding concentration, the overflow concentration, relaxation pump level, concentrate grade and recovery rates of the automatic monitoring and control. (4) The system is flexible control, with manual control. Fixed value control. Cascade control, model control, and self-optimizing control, can be used flexibly according to actual conditions. (5) system through the final quality (concentrate grade and recovery) indicator feedback, adjusting the process parameters to achieve optimal control of the whole process. (6) and grade of precision (relative error); concentrate for the disability z%. Ore is ± 3, ± 5 for the Niger mines. (7) abuse of the system flow measurement and control accuracy of the concentration of persons seized 1.5 (solid weight). (8) the amount of control precision mill to the mine who 1t / h. (9) the concentration of control error grinding of soil 2. (10) mill load control accuracy of ± 2%. (11) pump tank liquid level measurement and control accuracy of ± 2. (12) effects of the control system can control the overflow by 3 or more fineness, with a pass rate is normally close to 100, the operating rate increased by 1, concentrate grade increased 0.5N, table and processing capacity increased by 5 or more. 6 Application Overview KMRI - 500 control system since 1992, the company has been in the Jinchuan concentrator, Queensland actinium Roots of iron ore, Jiaojia Gold, Steel processing plant application. Pat achieved significant economic benefits. Practice has proved that the system concentrator grinding and classification process and sorting operations aroma control is effective. Has great promotional value. Income of 19,971,030 of B {Zhang Shouming blind. Kunming Metallurgy Research Institute of Automation of the original room engineer. Management has been that the Department of Automation, Kunming University, Kunming, Yunnan 650093, China Beihuan work} 38. Greater efforts to rectify the mining industry in Liaoning Province, Liaoning Province on the -4 order, 'that small coal mines, a small quarry. Little Zhi Jin Xuanye points post are rectification. Yielded good results. Mining order markedly improved. Tan is the mineral resources in Liaoning province. In some areas there are undocumented exploitation, indiscriminate, excessive digging and fruit, the same question illegal. Geology and Mineral sector to take blocking and sulfur, the whole combination of Qi and enabling approach. Temporary force against a larger reorganization. Three small mines. Exploitation of undocumented, the more layers the more give her a permit to open down dinner r Fu and depression behavior of products direct violation of Department, for the revival of most of the Fang only three small 'mines to be sealed. Confiscation of equipment. Street J} E undermine the reproduction of pieces of property owners. Pat on the small mining of a certain size have some pieces of mine Xi. Deadline for correction. 『Lead mines to the United bow sound type, stock. Development of intensive morning in his direction. Mining enterprises in Liaoyang City, the city inspection found 23 undocumented mining, with mining operation conditions of the formalities promptly. Feng Ting Yu firm mushroom. Some grant floor for Chen smaller character sets for iron ore mining gold and other conditions of small mines. To the \order to further improve. (magazine correspondent)
