The construction features of the modern automated system of selection, dosing, dispatch and delivery of dry concentrate samples implemented at JSCo “Lebedinsky GOK” are presented in the article. The generated system allows to fully automate the process of representative sampling, dosing, bagging in a shipping container, dispatch and unloading container with particulate iron ore concentrate having a temperature up to 100 оC. The system works in automatic and manual modes, has series of locks in low-pressure compressed air, finding a shipping container on the road, power outages and other emergency situations. In order to control the passage of shipping container used for pneumotrack sensors passing the container are applied, there are also position sensor actuators with visualization of the operations at the workstation operator at the station of sending and receiving containers. Diverter valves located at opposite ends of pneumotrack provide deceleration of transport container at the last part of the trajectory of motion and reduce buff load onto transport container. At all stages of selection and delivery, tightness of taken sample is ensured, and the high speed of its delivery allows embodying the operating control of moisture content of loaded concentrate. The functional diagram of a system is presented, original technical solutions describing used to develop the system is given. The article may be appealing to technical and analytical control services’ workers, experts in the field of automation of production processes.
