Information Control System for the Production of Mineral Fertilizers in the Granulator with a Fluidized Bed

A temperature control information system has been developed to ensure the production of high-quality granules with low moisture content. The study of the granulation and dehydration process, the main factors influencing the production of quality fertilizers, namely: temperature of heating air, temperature of granules, moisture content of granules, viscosity of the binder and its concentration.Based on the mathematical model, the transfer function of the granulator was obtained with the help of the Matlab software package, information control systems based on PI and PID controllers were developed, which should output and maintain the temperature of the granules at a given level. Their comparison is made to determine the system that better copes with the task. It is recommended to use a information control system with a PID regulator in the production, because it allows to reduce the consumption of gas used during the dehydration process, due to the faster achievement of the set temperature of the granules.
