to depend on coal quality. PCI rates of 200 kg/t HM are just like that practicable, earning you a little fortune of 180 kg coke/tHM plus the carbon footprint involved. What is more, stateoftheart technology by Küttner enables you to markedly increase PCI rates and benefit from lower raw material costs and higher productivity.

Grindability Index around 80. As these coals are very easy to mill, there will be savings from reduced mill power consumption for a given coal throughput. Low volatile coal also allows the mill capacity to be increased up to 40% above that of a 50 Hardgrove Grindability Index coal, thus allowing the steelworks to increase

Terence Bell. Updated on August 21, 2020. Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking. Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces.
