LOESCHE GmbH has for decades been involved in the research and development of coal processing plants with roller grinding mills. By intensive research work the engineers and technicians at LOESCHE GmbH, Duesseldorf, have successfully provided new coal processing technologies for the varied needs of industry. One of the first PCI Plants in Europe was equipped in 1985 by LOESCHE with two central coal grinding plants for the ironmaking plant at Dillingen, Germany. These two plants use hot stove waste gas in conjunction with blast furnace gas fired in a hot gas generator, as a heat source for coal drying. Further plant configurations have been developed and put into operation. Experience with self-inerted grinding plants (i.e., plants that do not make use of hot and dry waste gases) has been gained for various applications, such as coal gasification, liquefaction and pulverized coal injection into blast furnaces. In this paper experience and development of self-inerted, foreign-inerted and air-operated plants will be discussed.
