subject: Introduction Of Automation Of Mineral Processing [print this page] China's mineral processing industry is the traditional basic industries; already have a considerable scale, many practitioners. Outstanding problem is the high energy consumption, low efficiency, low level of automation and labor-intensive beneficiation technical and economic indicators, but also very unstable with the ore properties and operating conditions change. Concentrator is difficult to rely on manual production to be maintained at the optimal state. Is one important way to solve these problems is developed to study the key technology for the beneficiation of industrial production process, equipment, instrumentation and achieve beneficiation automation of industrial processes.
European Steel Industry and Technology Development guidelines state that: "to reduce production costs, improve product quality, reduce environmental pollution and resource consumption only through the whole process automatic control system optimal design to achieve the optimization of the whole process automatic control system is through the production execution system MES and process control system PCS optimal operation can be achieved. According to reports, the dressing automated processing plant to improve the metal recovery rate of 1% -2%; appropriate by the granularity of control grinding, control the means of the magnetic field strength, the concentrate grade increased by 0.4% -2%; by broken best load control of the ore mill ore operations, can be crushing capacity increased by 10% -15%, grinding the handling capacity of 2% -10% 5% -10%, save energy, reduce production costs by 3% -5% labor productivity increased by 25% -50%. The role of automatic control product quality and stability, achieve downsizing to improve efficiency is self-evident. (Crusher)
The beneficiation of industrial production process automation, which includes: crushing operations, grinding and classification operations, and sorting operations, dehydration filter operations and thickener concentrate, tailings delivery operations, and other automatic control of the production process of the whole process of beneficiation. Optimize production scheduling and management of online computer network system, so that the whole dressing production process at its best to maximize the economic indicators of production, concentrate grade and metal recovery technology to achieve high yield and quality, energy saving purposes. (Mill)
In the field of mineral processing automation, the most widely, the technology is basically mature, significant effect of several technologies including PLC control of the process of crushing, grinding process of multi-parameter control, new and efficient separation column, column flotation choose the automatic control of other devices, liquid level automatic control of flotation process based on the grade analysis of automatic dosing, mine paddle. Parameter detection, in addition to the regular amount of ore, flow, level, power, pH, substandard, automatic monitoring of the beneficiation process key parameters such as mill load, the grade of ore oar, slurry particle size, flotation froth image analysis etc. can play a good role in guiding the process operation. In addition, the energy saving effect of frequency control technology dressing production. Expert systems, fuzzy control, combined with application optimized to control self-optimization, neural network control and advanced control and stabilization, but also can significantly improve the beneficiation process control application.
