Control algorithms and signals of the pnevmotransport system stations at the enterprises of the mining and metallurgical complex

Automatic control of any technological process provides for continuous or periodic monitoring of the parameters that determine this technological process. For mining, processing, metallurgical plants and factories, such a parameter is the chemical composition of the feedstock, fluxes, reagents used, intermediate products, finished products, dump tailings and discharged wastewater. Information about the chemical composition of these products is obtained by selecting and then analyzing representative samples. The purpose of this work is to develop a container delivery system for technological materials based on the use of unified nodes operating under the control of a universal microprocessor system. The solution of this task makes it possible to simplify the process of adapting the system to a specific technological process, increase its reliability through the use of unified nodes and simplify maintenance during operation. The scheme of the container delivery system of technological materials, which includes stations serving the process of container transportation, has been developed. The stations are made on the basis of unified nodes and elements. Such nodes of the stations include: pneumatic cylinders, electropneumatic valves, distributors, magnetic sensors.
