Dear Sir,
What are the main reasons for ball formation in kiln as our raw mix analysis as below
LOI = 37.0%
SiO2 = 12.2-12.5
Al2 O3 = 3.4-3.5
Fe2O3= 3.1-3.3
CaO = 41.2-41.5
MgO= 1.8-2.2
SO3 = 0.5-0.6
Na2O =0.4-0.5
K2O = 0.2-0.3
Cl =0.12-.14
LSF = 101-103
SM = 1.9-2.1
AM = 1.0-1.1
Residue on 90 micron = 14-15%
Resisdue on 212 micron = below 1%
We are using the south African coal "A"
Regards
Surendra
