The average kiln in use today is capable of producing 89.9 percent more clinker than an average kiln produced 20 years ago: 678,000 metric tons in 2012 compared with 357,000 metric tons in 1992. The cement industry has boosted efficiency by concentrating new capital investment in plants that use the dry process of cement manufacture, and by phasing out operations that rely on the more energy ...
RAW GRINDING Raw grinding and burning 2. BURNING 2. BURNING : The raw mix is preheated before it goes into the kiln, which is heated by a flame that can be as hot as 2000 °C. The raw mix burns at 1500 °C producing clinker which, when it leaves the kiln, is rapidly cooled with air fans. So, the raw mix is burnt to produce clinker : the basic material needed to make cement. conveyor Next Raw ...
