Metinvest Group’s Central Mining and Processing Plant (CMP, Kryvyi Rih, Dnipro region) has modernized its pellet production equipment.
According to the company’s press release, the pelletizing plant has completed a major overhaul of the OK-324 roasting machine.
It is specified that the pelletizing plant’s process equipment operates continuously, around the clock, for more than 7.5 thousand hours a year, so its technical condition is of high priority. The repairs were carried out as part of the pellet production process optimization program.
“One of the key areas was the restoration of the refractory masonry of the roasting machine’s furnace and the repair of six nozzles. This is crucial for maintaining the thermal insulation of the roasting machine’s furnace space and will help avoid the destruction of the brickwork and ensure continuous operation during the overhaul period,” explained Andrey Ivanov, Deputy Head of the pelletizing plant at the Central Enrichment Plant.
Reportedly, an experimental solution was also implemented during the repair to apply shotcrete to the surface of the No. 9 and No. 10 tanks. This can significantly increase the resistance of refractory insulation by reducing the impact of biofuels. Additionally, the drip traps of smoke exhausters D2 and D5 were repaired, and three sections of drip trap No. 2 of smoke exhausters D2 were completely replaced. This will help reduce emissions and improve the gas dynamics of the heat flow.
The installed shaft rotation of the D3 smoke exhauster will reduce the equipment’s operating time during the plant shutdown for scheduled repairs, help reduce energy consumption, and increase equipment reliability. In addition, the conveyor transport was maintained, including the replacement of rollers, seals, and lining of the reloading units.
