grinding mill for blast furnace slag liberia Top equipment of blast furnace slag composite dust and limestone largescale processing High Capacity Advanced Technology High Efficiency HLM series vertical grinding mill is a kind of advanced pulverizing equipment integrated with drying pulverizing powder selecting and conveying
The blast furnace uses both high calcium andor dolomitic limestone A few trials have been made using iron oxide stabilized dolomitic lime in an attempt to reduce coke consumption and to increase the production rate
Blast furnaces produce pig iron from iron ore by the reducing action of carbon supplied as coke at a high temperature in the presence of a fluxing agent such as limestone Ironmaking blast furnaces consist of several zones a crucibleshaped hearth at the bottom of the furnace an intermediate zone called a bosh between the hearth and the stack a vertical shaft the stack that extends from the bosh
Ironmaking Blast Furnace Iron is made by reacting iron ore iron oxide and impurities coke a reductant and limestone CaCO3 in a blast furnace Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities
The sintering technology was originally developed for the purpose of utilizing in the blast furnace the iron ore fines and the iron present in the metallurgical waste of a steel plant But currently the focus has changed Now the sintering process aims to produce a high quality burden for the blast furnace
Blast Furnace During ironmaking agglomerated iron ore is combined with prepared limestone si lica and coke and placed into a blast furnace Heated air is blown into t he furnace and causes the limestone and sili ca to form a fluid slag which combines wi th other impurities
