Roller grinding mills are increasingly being used to produce the pulverized coal required for injection into blast furnaces which has become an accepted technology worldwide for lowering coke consumption. Coal is now being injected into blast furnaces at the rate of 80 to 200 kg/ton of hot metal and this results in a coke saving of 72 to 180 kg/ton of hot metal. The pulverized coal needed for coal injection is produced in coal grinding and drying plants. At present these plants range in capacity from 15 to 240 tons/hr. As an example, the coal grinding plant with Loesche roller grinding mills in operation at the ILVA steelworks in Taranto, Italy will be described in detail.
