Automatic Controlling Application Research Of The Mineral-piling System Of Ore Dressing-press

The mineral-piling system of ore dressing process mainly undertakes the loading and transportation of minerals, it's an important link in the production of limestone, it also decides the success or failure of mineral-providing. The research topic aims at the realization scheme of the automatic controlling, to change the present situation of man-controlled limestone and the low-level automatic controlling, it lays the solid foundation for the overall data and automatic process.The mineral-piling controlling system of ore dressing process applies collecting and distributing controlling, the whole system sets up a set of PLC as the controlling core of the system, and a set of operating station as its controlling and operating management. It joins as a small collecting and distributing controlling system through computer software in industry The process mainly involves the mineral-piling system's distributing of belt conveyer, it ends product storehouse and the work of automatic controlling design for loading.The research topic uses the mineral-piling working procedure of the ore dressing process of The China Aluminum, Guizhou Branch, as the worksite controlling unit. Through 2 basic platforms, by PLC and operating station, the PLC linked by the worksite general line and display operating end, it assembles the production controlling, data collecting, affairs dealing as a unified system, it consists the foundation of the business management and business information, it realizes the data collecting, storing, calculating, displaying, alarming and typing of the limestone's transporting industrial process, it reveals by the flow diagrams, tendency diagrams, stick-like diagrams and charts. Through the monitor of the major industrial procedure, product equipment and aid-product equipment, it finishes the basic management of industrial process. It helps the controlling system meet the real conditions of mining production. Only the systems operate stably and safely, it can conveniently adjust the controlling tactics according to the changing of the technology, it also reduces the production costs. So it has profound historic significances both in technical meaning and social meaning.
