INTELLIGENT SYSTEM FOR AUTOMATIC MONITORING OF QUALITY AND QUANTITY OF ORE FLOW IN PROCESS OF PREPARATION FOR CONCENTRATION

摘要

FIELD: measurement technology; mining.;SUBSTANCE: invention relates to automatic continuous monitoring of qualitative and quantitative characteristics of ore flow during its preparation for concentration. Device contains automatic ore weighers and camera with video driver. Camera eyepiece is directed onto ore surface on vehicle. There is also video camera image processing unit, magnetic sensor of iron concentration in supplied ore, marking scanner of ore for decoding of qualitative and quantitative compositions of delivered ore corresponding to product passport. There is complex data unit in form of digital cluster decoding of markers of ore supplier. Device includes recording unit of ore chemical composition, automatic weighers of supplied ore, at least one unit of ore size assessment, at least one movable X-ray spectrum analyzer of chemical-mineralogical composition of ore. There is computer system evaluating nature of splices and calculating average number of target minerals in crushed ore particles and calculating percentage of desired minerals in ore flow. Device comprises at least eight elements of comparison of measured signals of parameters' character generated at output of said means of continuous and testing monitoring of quantitative and qualitative characteristics of processed ore. Video camera output through camera image processing unit in sequence via unit for estimating size of pieces and particles of ore is connected to one of computer system inputs. Output of markings reading scanner of supplied ore is connected to input of digital cluster decoding of markers by qualitative and quantitative composition of supplied ore by passport, corresponding decoding marker of supplier. Wherein one output of unit of registration amount of supplied ore is simultaneously connected to first input of comparison element and one input of computer system. Other output of chemical composition unit of supplied ore is connected to first input of comparison element and another input of computer system. Output of automatic weighers is simultaneously connected to another input of comparator for comparing quantitative values of weights of ores and one of inputs for taking accounting quantitative values of ores.;EFFECT: increased efficiency of monitoring and reliability.;1 cl, 2 dwg
