- Abstract
The issue of ring formation in rotary kilns poses a significant obstacle to the efficient and cost-effective production of oxide pellets. This study focuses on sampling and analyzing deposit formation at various points along the longitudinal axis of a 40-m-long, high-silica, pellet coal-fired rotary kiln. The primary factors influencing deposit formation in the kiln are fines generation and liquid phase formation. Through laboratory experiments and utilization of the "FactSage" calculation system, measures to reduce fines generation and inhibit liquid phase formation are analyzed, thereby establishing a foundation for mitigating deposit-forming speed in rotary kilns and increasing pellet production.
