Development of an automated control and management system for a fertilizer mixing plant

Abstract

Relevance. The use of complex multicomponent fertilizers in some cases is unjustified economically and can often lead to soil degradation. In such cases, in order to ensure the plantʼs need for the necessary nutrients, it is advisable to use fertilizer mixtures with a given number of components. Thus, in order to comply with the exact proportions of the components of the created fertilizer mixture, the task of creating an automation system becomes urgent, which includes not only a machine for mixing with a high coefficient of unevenness of the resulting fertilizer mixture, but also a software package for determining the component composition of the fertilizer mixture depending on the conditions of the economy, as well as an automated system of weight control and control of metering dampers working together.Methods. The technologies of production of flour mixtures are considered, the main types of mixing used in their creation are determined. To implement the project on automating the processes of flour mixing at the developed technological installation, the methods of analytical, comparative, information and logical analysis of the initial information were used.Results. А system of automated control of the technological process of fertilizer mixture was obtained at the developed fertilizer mixture plant, which allows using the joint work of all components in it to calculate the necessary composition and formulation of the fertilizer mixture, to obtain high-quality fertilizer mixtures due to accurate dosing of components and their biological modification.
