Abstract
Abstract The processing of industrial raw materials, the development and implementation of new technologies for their beneficiation, and the use of the resulting products are among the most important factors influencing the development and recovery of Ukraine, and are of paramount importance not only for economic growth but also for our environment. The active use of industrial mineral waste will generate billions of dollars in profits annually. Studies were conducted on the fractional composition and properties of wet (with a moisture content of 30%) and dry coal sludge from the storage pond of the Pavlohrad Central Coal Processing Plant. It was established that fine classification using a vibro-impact screen can produce marketable products from high-ash sludge with characteristics that meet the regulatory standards for coal supplied to thermal power plants. The completed studies on the processing of dry and wet sludge from storage ponds demonstrated the potential and feasibility of their processing using the new vibrating impact screen. Involvement in the processing of industrial waste will ensure: profit generation and increased profitability of enterprises; the release of land occupied by waste; and an improved environmental situation around existing enterprise.
