These have been used for many years for the less exacting raw-milling process, but recently roller mills, in combination with high-efficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption

The ground coal allows more efficient combustion, because in the process one will achieve two important purposes on coal: * The dehydration since moisture reduction has a positive effect on the rate of heat transfer. * The increase of specific surface area, i.e. the carbon surface exposed to combustion per unit volume.

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). But, this wet slag cannot be directly put into the ball-mill (where grinding is done) as

Presently we use coal from China and South Africa, maintaining volatile matter in fine coal below 32 per cent. We use cooler exhaust gas (ambient) for coal mill drying. We want to use coal from Indonesia having about 42 per cent volatile matter. Is it safe to grind in the coal mill having hot gases from cooler?
