The coal based direct reduction rotary kiln process wasdeveloped for converting iron ore directly into metallic iron without the melting of the materials. The process has the advantage of low capital expenditure and no requirement of coking coal.Get Price
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
This series of jaw crusher belongs to stone crushing equipment which is widely used in the works of metallurgy, mining, cement, chemistry, refractory and ceramics as well as highway construction and water conservancy.
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
The sand washer is a kind of highly efficient sand washing plant, taking the advanced techniques and the domestic physical conditions together into consideration.
Coal Based Rotary Kiln for Direct Reduced Iron / Sponge Iron (100 TPD, 350 TPD, 500 TPD) Solid state reduction ofIron Oreusing either coal/gas as a medium of reduction to produce a substitute raw material for steel making is termed as Direct Reduced Iron (DRI). Since DRI is produced by removing oxygen from iron ore, its structure is just like sponge with a network of connecting pores.

During the sintering process in a rotary kiln, adjusting thecoal feeding rateis the main way to keep the sintering temperature stable. In this paper, a novel method named PSR-PCA-HMM is proposed to predict the coal feeding state by integrating principal component analysis and the hidden Markov model based on phase space reconstruction.
Sep 01, 2015· In conventional coal based sponge iron plant, Fig. 1,kiln feed (Stream no. 1), whichconsists of iron ore,feed coal and dolomite, isfed 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.
The coal-based processes can be grouped into four categories according to their reduction reactors. The rotary kiln processes includeACCAR/OSIL,DRC,Krupp-CODIRandSL/RN processes.Kinglor Metor...
