how coal is used to manufacture 1 ton of cement; What is the use of coal in the cement manufacturing , Primarily for cement grinding plants in India, coal (generally of bituminous grade) is used in the slag-dryer The wet slag arrives at the stack on wagons from some nearby steel plant, or it may be brought via a trolley-system (primitive mode) .
Sustainable Manufacturing As cement producers continue to search for alternative fuels, many people wonder what types of fuel can be used in the combustion process The average energy input required to make one ton of cement is 44 million Btu—the equivalent of about 389 pounds of coal
Since the quality of coal is poor (high ash content) and inconsistent, this leads to problems of quality control for cement plants Sometimes, although coal is available, rail transport is not, which forces cement manufacturers to transport coal using trucks, or purchase coal from neighbouring consumers who have not used their coal allocation
