This study focuses on sponge iron kiln based process. The chemical process involved in making sponge iron removes oxygen from iron ore by using a reducing agent in the form of non-coking coal Patra et al, (2005). The reduction process is carried out in an inclined horizontal rotary kiln, which rotates at a programmed speed. 5.1 SPONGE IRON PLANT There is a plan to install 4x100 TPD DRI kilns for production of 1,20,000 TPA sponge iron. Manufacturing Process The proposed plant uses the coal based process in which iron oxide in pellet/iron ore will be reduced with non coking coal in a rotary kiln to make sponge iron.

BACKGROUND OF THE INVENTION. 1. Field of the Invention . This invention relates to a process of directly reducing iron oxide-containing material to produce sponge iron in a rotary kiln by a treatment with solid carbonaceous reducing agents having a high content of volatile combustible constituents, e.g., 25 to 50 weight percent in which the charge is moved through the rotary kiln opposite to ... Jun 22, 2018 Rotary kilns run 24 hours a day, and are typically stopped only for a few days once or twice a year for essential maintenance. One of the main maintenance works on rotary kilns is tyre and roller surface machining and grinding works which can be done while the kiln works in full operation at speeds up to 3.5 rpm.

Metallurgical chemical kilns are mainly used for the magnetic roasting of lean iron ore The size of a rotary kiln is not only a function of capacity, but also of the amount of heat that can be generated inside the rotary kiln from the volatizing and/or combustion of the material. The diameter Dams For various reasons, it is often desirable to increase retention time or bed depth in the rotary kiln.

Consequently, sponge iron making in rotary kiln flourished first in South Africa, and now India produces over 70% of coal based sponge iron in the world. It is very easy to reduce the higher oxides of iron to FeO stage. One only needs to meet the heat demand, the May 01, 2013 Sponge Iron (SI) DRI is also known as Sponge Iron because of its spongy micro structure. ore lumps or iron ore pellets with the help of non-coking coal in Rotary Kiln (in Coal based Plants) .. But usually iron content of ores ranges between 50-65/67% (rich ores) and 30-35% (lean ores) . Sinter Plant /Cement Industry More detailed

Mar 01, 2017 Introduction. Rotary kiln is the primary equipment in sponge iron industry, which is used to reduce iron ore to metallic iron i.e. Fe. It is called sponge iron. Rotary kiln is widely used in cement and steel industries. The production capacities of these industries depend significantly on the performance of rotary kiln. Jun 01, 2016 In the sponge iron industry rotary kiln is the primary equipment, which is used to reduce iron ore to metallic iron i.e. Fe. Though sponge iron is a hard solid material, it is called sponge iron due to its honeycomb structure. Rotary kiln is also widely used in cement industry.
