Abstract
The study focuses on improving the energy efficiency of dewatering finely ground iron ore concentrates to produce raw materials suitable for Direct Reduced Iron (DRI) technology. The aim is to compare the energy efficiency of DU-100-2.5 fabric vacuum filters and KDF-90 ceramic vacuum filters, as well as to determine the optimal operating parameters of the latter to achieve a moisture content in the concentrate within the range of 9.0–9.5% with minimal energy consumption. Experiments conducted at PJSC "CGOK" demonstrated that ceramic filters provide a productivity of 0.7–0.9 t/m² and reduce energy consumption due to the capillary action of micropores and effective regeneration. The scientific novelty lies in the development of a mathematical model for predicting residual moisture with an average accuracy of 0.17% and a convergence value of 0.9787. The practical significance is the potential implementation of an energy-efficient technology at domestic enterprises to enhance competitiveness in the concentrate markets.
