Cement. While attempting to develop his ore milling process to concentrate lowgrade iron ore, Edison found that he could sell the waste sand to cement manufacturers. In 1899, he decided to investigate how he might transfer his rockcrushing technology to the production of Portland cement.
2) System shows the length of the roasting zone and the time of high temperature for pellets, so the system provides a theoretical basis to guide rotary kiln Issue 4 Temperature Field Simulation Model for Rotary Kiln of Iron Ore Oxidized Pellet 19 ' production.
Jul 29, 2010· The reduced iron ore SPONGE IRON with unburnt char from rotary kiln gets discharged into a Rotary Cooler. The heat will be dissipated indirectly by water spraying into the outside of Cooler Shell. The material gets cooled to around 1200C.
Iron Ore Processing for the Blast Furnace ... grab the iron particles and the rest is discarded. For every ton of iron retained, two tons of waste, or tailings, are discarded. ... From this point, the pellets are charged into the large rotary kiln where they are heathardened at 2,400 degrees Fahrenheit.
Rotary Kilns are commonly used for heat processing of minerals and aggregates such as lime, cement, and iron ore. To achieve consistent quality results, it is important to maintain a uniform product temperature at the kiln entry, mid zone, and discharge.

Sponge iron being magnetic gets attracted and gets separated from non magnetic char. The iron ore and coal crushed and screened to respective sizes are fed to rotary kiln through feed tube in predetermined ratio. The rotary kiln is slightly inclined at an angle deg and rotated by
The simultaneous effects of three major processing variables upon the extent of reduction of iron ore pellets and the physical properties of the reduced product have been investigated under closely controlled conditions in a small rotary kiln.
Rotary kiln process for iron ore oxide pellet production is hard to detect and control. Construction of onedimensional model of temperature field in rotary kiln was described. And the results lay a solid foundation for online control.
Rotary kiln is cylindrical in shape and is 80m long having internal diameter. This is the reactor of the process where reduction as well as combustion reactions are carried out. The role of kiln is to convert the raw material (iron ore, coal and dolomite) into the sponge iron [8]. Detail reaction mechanism of the process is discussed below:
reduces iron oxide (ore) to iron. So, in a kiln, there are two sources of energy, one in the lance injecting coal particles from one end and the second is the coal in charge bed where reduction of iron ore occurs. The air tubes are located along the length of the kiln and they inject air into the kiln.
Iron ore is the main form of iron oxide, and iron ore rotary kiln is mainly used in calcining, the production of iron orebased metal mineral raw materials, the main equipment, through the redox reaction, the iron ore raw materials purification, processing and utilization, the whole machine production is stable, the kiln product quality is high ...
Sponge iron is the product generated by direct reduction of iron ore with aid of either carbon or natural gas under controlled temperatures and pressures within a rotary kiln. However the performance of rotary .
