    Raw materials Steel production. Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then purified or carbonised in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100 C in the absence of oxygen for 12-36 hours.

    Coal Global Energy Review 2020 Analysis IEA

    We expect global coal demand to fall by about 8 in 2020, the largest drop since World War II, with coal use declining in virtually every sector of every region in the world. In China, coal demand will decline in 2020 by around 5, despite the gradual recovery since February lockdown. Coal-fired power generation will be hit especially hard, because the power system is crowded by low variable ...

  • Vertical Roller Mills FLSmidth

    Vertical Roller Mills FLSmidth

    When it comes to grinding raw coal, savings in specific energy consumption can be achieved with vertical roller mills. Specific energy consumption depends on the grindability of the raw coal and the coal meal fineness required. A dynamic separator that ensures high separation efficiency also helps to reduce specific energy use.
