Abstract

As a part of the comprehensive programme for produc avi ty optimisation, energy censer va tion and trouble shooting, The Associated Cement Companies Ltd. (ACC) an organization with 17 factories, 48 kiln s and about 9 milli on tonnes of installed capacity ha ve been taking advantage of plant scale use of minerali sers under eli verse process condi Li ons. This approach has led to ex tensive use of fluori te, compounds os the rnineralisers in wet and semi -dry kiln systems of 300-600 tpd range. In order to reeal the thermo -chemical effec t of differen t mineraliser or. industr ial raw mixes a new technique based on fi ring shrinkage of kiln feed pellets have been developed. The applica tion of this technique for predi - cting the change in the c ourse of lime combinabil i ty reac tion wi th and without use of mineralisern has been repor ted in the present a rtic le . The changes obtained in the quali ty of c linke r with the use of Fluorspar as mineraliser under ac tua l plant co01ditions have been studied. At tempts have been made to find ou t the re tention and dis tribution pattern of minera lising ions in various phases of the indus t ria l cl inkers. An endeavour has been made to cor re late the change in c linker quali ty with dis tribu tion pattern of mine ral ising ions in c linker phases as well as with the course of lime combinabi li ty reac Lions established through the technique of fir ing shrinkage of raw mi x pelle ts. fluorosi l ica te and sulpha te
