    Q: Why big clinker ball formation happens? Re: High Iron %age in Raw Meal High sulfur %age in fuel Clinker is burning with slow Kiln rpm and filling is more High burning zone temperature High %age of liquid phase High %age of Magnesia(MgO) Q: What are the reasons of feed rush and dusty kiln and what actions can be taken?
