Rotary kiln Wikipedia

A rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include: Cement · Lime · Refractories · Metakaolin · Titanium dioxide · Alumina · Vermiculite · Iron ore pellets. They are also used for roasting a wide variety of 

Tunnel Kiln Based Sponge Iron Plant Horizon Consultants

The nonconventional method of making sponge iron is done in the tunnel kiln process as compared to the old rotary kiln process. In the conventional process of tunnel kiln process, the iron ore and coal are fed in the crucibles or saggars of silicon carbide and loaded on the trolleys. These trolleys are then fed to the tunnel

(I) Solid iron DRC etc. Sponge/ . DRI Iron Rotary Hearth Fastmet etc.,. (b) Natural gasbased Shaft furnaces, Midrex,. Fluidised beds 

Coal based Direct Reduction Rotary Kiln Process ispatguru

Feb 14, 2017 The coal based direct reduction rotary kiln process was developed for converting iron ore directly into metallic iron without the melting of the materials. The process has the The reduced product having high degree of metallization shows a 'honeycomb structure' due to which it is often called sponge iron.

Rotary Kiln Process of Making Sponge Iron New Age International

As touched upon earlier, sponge iron is mainly produced from ore by two different routes – (a) by reducing gases (CO and H2) in a shaft furnace, and (b) through direct treatment with coal in a rotary kiln. 2.2 IMPORTANT FEATURES. The coal based rotary kiln process of making sponge iron is the focus of the present write.

2 D Model of Sponge Iron Rotary Kiln Developed Using CFD IJEDR

Abstract: The present paper deals with 2D CFD model of rotary kilns employed in sponge iron process. Using this model the effects of variations of input parameters, such as angle of inclination, number of rotation and mass flow rate of iron ore are studied on output parameters like Fe content, and temperature profile.

Simulation of Rotary Kiln Used in Sponge Iron Process Using IJET

Index Terms—Sponge iron process, rotary kiln, temperature profile alternative to steel scraps in iron and steel making processes. With the along the length of the kiln. To produce sponge iron, iron ore and coal are used as raw material. In the kiln coal is injected from feed side, which is called feed coal as well as.

Energy Audit Methodology of Sponge Iron Manufacturing Units

Further, the average heat to power ratio (kWth/kWe) of sponge iron plants ranges from (25:1) to (31:1). This shows that the manufacturing process mostly uses thermal energy and appliion of electrical energy is insignificant. The main & only source of thermal energy is coal and the entire coal is fed to the rotary kiln.

Manufacturing Process Sree Metaliks Ltd

Most solid reductant process use coal as reductant due to abundantly available noncoking coal. The different coal based processes include retort/shaft, tunnel kiln, rotary kiln, Lurgi etc. The process to be adopted is the rotary kiln process using lowgrade coal to reduce sponge grade iron ore. The locally available raw
