Alibaba.com offers 231 spong iron rotary kiln products. About 75% of these are cement making machinery, 6% are other mining machines, and 3% are industrial furnace. A wide variety of spong iron rotary kiln options are available to you, such as free samples.
Rotary kiln is cylindrical in shape and is 80m long having 4.2m 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 . Detail reaction mechanism of the process is discussed below:
Aug 03, 2011 · COAL INJECTION IN ROTARY KILN K.Ramu, C.Ramesh, A.Rajasekaran During the process of manufacture of sponge iron, coal injection plays a very vital role in maintaining the product quality. Due to highly endothermic nature of Boudouard reaction, heat has to be continuously supplied in entire reduction zone of rotary kiln.
(1) Economical aspect. Crude ferronickel can be produced at a low energy cost, using a rotary kiln after pretreatment of the raw materials. 2. (2) Availability of the product. The crude ferronickel product can be well utilized as the raw material in the AOD stainless steel making process.
