Abstract: The tailings workshop of the processing plant of JSC Lebedinsky GOK is the highest priority in terms of modernization, improvement and reconstruction, because the most of the equipment used in the workshop is outdated and cannot fully provide the necessary efficiency. Unplanned idle time of P-50 thickeners due to equipment malfunction is up to 50 hours per month or up to 7% of their monthly operating time. The purpose of this paper is to substantiate the necessity of reconstruction of a P–50 radial thickener with a peripheral drive using design and an improved drive of a thickener with a central drive C-50. The main methods used for the applied research include an analysis of technical solutions, selection of design characteristics, technical and economic comparison of options. The identified shortcomings of the P-50 thickener are proposed to be eliminated by installing improved drive equipment and metal structures of the C-50 thickener into the P-50's bowl. Replacing different types of mechanical gears with a planetary gearbox with a large gear ratio will increase the reliability and efficiency of the drive of the C-50 thickener. The calculation of economic efficiency shows the feasibility of implementing the project, since the payback period is 1.1 years. The results of applied research can be useful in the reconstruction of tailings workshops of ore processing plants, most of which still use similar thickeners.
