The paper presents a proposal to reduce the cost of the pipeline transport of hydromixture in the lime production process. The purpose of the research was to reduce the energy and water demand during the flow of lime hydromixture with a deflocculant of a specific composition in a selected pipeline. Since the addition of an appropriate deflocculant significantly reduces the effect of particle size on the flowability of the suspension, the selection of optimal transport conditions is a fundamental issue. To provide the most efficient transport condition of the hydromixture tested in the analysed pipeline, a mathematical model has been developed that assumes the most influential factors in the operation of the investigated enterprise technology. The input parameters are proposed using a statistical method. In the article, the consumption costs of the components (materials and energy) in the process of piping a lime hydromixture of different mass concentrations were compared. The analysis carried out aimed to reduce the amount of electrical energy needed to drive the pump during the flow of a hydromixture of four different mass concentrations and its volumetric flow rate in the pipeline, while maintaining a constant amount of the transported mass of the solid phase in the hydromixture. The results of the analysis revealed that controlling selected operating factors, such as the mass concentration of the hydromixture, the flow rate, and the pump head, improves the energy efficiency of the hydrotransport process in the limestone mine. As a result of the investigation, significant reduction of the total cost of the pipeline transport is possible.
