Jan 26, 2020 Sponge iron plant rotary kiln and cooler list of machinery spare parts and casting and forging technical procurement specifications budgetary cost for coal based, gas based, electric based sponge iron plant for 50 TPD, 75 TPD, 100 TPD, 150 TPD, 175 TPD, 200 TPD, 300 TPD, 350 TPD, 500 TPD, 600 TPD Tons per day.
The overall process of direct reduction takes about 10 to 12 hours inside the kiln. During this time, iron ore is optimally reduced and the hot reduced sponge iron along with semi-burnt coalchar is discharged to a rotary cooler for indirect cooling to a temperature of between 100 C to 120 C.
Thirdly, the flammable part of the hazardous waste can be decomposed into harmless gas after being fully burned the harmful dust in the flue gas is collected by the rotary kiln and after the treatment dust can achieve safe discharge standards the indirect rotary kiln can fix most of the heavy metals in the waste in the clinker to avoid re ...
rotary kiln operations. Regardless of rotary kiln size or configuration the basic principles outlined in this manual govern the reliable operation of every rotary kiln, calciner, dryer, incinerator, digester and cooler application.

Sep 01, 2015 In conventional coal based sponge iron plant, Fig. 1, kiln feed Stream no. 1, which consists of iron ore, feed coal and dolomite, is fed to the rotary kiln RK.A separate conveyor collects different size fractions of coal Stream no. 5 for injection into the kiln with the help of pressurized air Stream no. 4 from discharge end side.
6. The product i.e. Sponge Iron and semi burnt coal are discharged from the kiln through a rotary cooler. The cooler is 12M in length and water is sprayed directly as well as indirectly for cooling the material. The material is cooled down to 100oC and fed to magnetic separator for separating the sponge iron and non-magnetic char. The Sponge ...
The hot product discharged from the kiln is indirectly cooled in a rotary cooler by spraying water on the shell of the cooler. The discharge from the cooler is conveyed through a belt conveyor screened and magnetically separated. Sponge iron and non-magnetic components are separated and stored in separate bins for further transfer.
