Sir, We are using Bauxite and Iron ore as flux for type 1 clinker.Now that bauxite is costing more when compared to Iron ore Is it possible to reduce bauxite consumption cosiderably and use iron ore in its place..In that case to what extent we go down in bauxite consumption and what are all the operational difficulties we come across??Your valued advice is highly appreciated.

You can try bauxite's residue, i.e. red mud. It has around 45wt% of hematite and there is a track record of industrial trials in India, China and Greece.

hello dear
bauxite and iron ore two different compositions........if you want to reduce the consumption of bauxite , it will be depend upon the chemical analysis of both materials
As I understand,the optimum requirement of Alumina,Iron,lime and Silica in Type1 clinker is predominantly fullfilled by Bauxite, Iron ore, limestone and Sandstone/Clay respectively.
By reducing bauxite and increasing iron ore modullai values LSF,SM and AM will change and likely to have unfavourable impact on clinker properties such as easy burning mix and tendency for balling in burning zone,unstable kiln and cooler operation and lower strength of clinker
