  • Automated Control System for Magnetic Desliming

    The desliming process plays a key role in mineral processing technology, ensuring efficient particle separation based on their magnetic properties. The article examines the issues arising from the use of traditional magnetic deslimers under elevated slurry temperatures. One of the main drawbacks of existing methods is the decrease in magnetite density as temperature rises, which impairs separation quality and leads to losses of the valuable product. The article explores the physical aspects of this problem and proposes methods for its mitigation, including control of the magnetic field strength to optimize flocculation. It also considers the possibility of upgrading deslimers by replacing permanent magnets with electromagnets, enabling more precise process control. Magnetic field modeling with ANSYS Maxwell software confirms the effectiveness of the proposed solutions. The work’s primary focus is the development of a hybrid intelligent control system for the desliming process. The proposed system consists of three control loops: water supply, electromagnet excitation current, and desliming discharge. Each loop is managed by proportional–integral–derivative regulators, which are automatically adjusted based on data regarding changing slurry parameters and external conditions. Applying these methods can significantly improve the quality of the iron ore concentrate, increase the iron content in the product, reduce losses in tailings, and ensure stable equipment operation under varying environmental conditions.

  • Development of a circuit with pulsating circulation of liquid coolant in the circuit of a plate heat exchanger

    A laboratory circuit of the installation with a heat exchanger-supercharger in the hot water circuit of the boiler has been developed. The conducted studies have shown that the temperature of hot water at the outlet changes depending on the oscillation frequency of the electromagnetic valve at a given flow rate, and the highest efficiency of water heating is observed at a frequency of 1.75 Hz. Calculation of the heat transfer coefficient showed that at a steady-state flow rate, the heat transfer coefficient of the heat exchanger-supercharger is 180 W / (m ^ 2 ° C). Then, with increasing frequency, the heat transfer coefficient smoothly decreases and reaches a minimum of 173 W / (m ^ 2 ° C) at 1.0 Hz. With a further increase in frequency, the heat transfer coefficient begins to increase and reaches a maximum of 188 W / (m ^ 2 ° C) at 1.75 Hz. As a result of the experiment, it was also found that with increasing frequency, the flow rate in the hot water circuit increases and reaches a maximum at a frequency of 1.75 Hz Q = 0.6 l / sec. That is, at such a frequency, the heat exchanger-supercharger, due to the oscillations of the liquid flow in the first circuit (cold water circuit), most effectively transmits the oscillations of the flow to the second circuit (hot water circuit), which can be used to reduce the power of the pump in the hot water circuit at this frequency.

  • Approaches to optimizing the production process management system at the enterprise

    Finding ways to improve the efficiency of the production process at precast concrete plants is a relevant area in production management. It is necessary to take into account the specifics of the entire production process. Identifying opportunities to improve the production process management system is critical for any organization seeking to increase efficiency, reduce costs, and improve overall productivity. Production process management involves taking into account many variables, such as labor, equipment, raw materials, workflow, and more. Production management is aimed at optimizing production and finding a balance between the quality and productivity of manufactured goods, as well as the time and resources spent on their production. When studying ways to improve the production process, managers focus on two key parameters: productivity and product cost. When setting goals to reduce costs and increase productivity, managers must take into account these closely interrelated elements. But despite the obvious connection between productivity and cost, attempts to improve these parameters are often made separately. The purpose of the article is to identify approaches to optimizing the production process management system at an enterprise. The study is practically significant due to the fact that the development of approaches to optimization of the production process management system at the enterprise will help to use these approaches in the production process management system.

  • A software complex for modeling the control system for the pasteurization of canned fish

    During the production of delicatessen canned fish, the control system should ensure a gentle heat treatment regime with a decrease in the degree of temperature exposure to the product. Changing the modes requires reconfiguration of the type and parameters of temperature regulators in the autoclave, carried out based on the results of processing modeling. The software complex for modeling the object and control system during pasteurization provides for calculating the degree of sterilizing effect. The complex contains system and application softwares. The application modules implement the functions of a graphical interface, a virtual controller, numerical simulation of product temperature changes and data transmission. The virtual controller allows select controllers: positional, proportional-integral-differential, and states. The novelty of the model lies in the display and the possibility of changing both the parameters of the regulator and the coefficients of the desired polynomial, taking into account the sign of the derivative of temperature during heating and cooling. The practical value of the work is to reduce the time for reconfiguring the autoclave control system, ensuring a reduction in the degree of temperature exposure when a given sterilizing effect is achieved by selecting the type and parameters of temperature control rules.
