| Abstract Scope |
The quality of sinter depends on its raw material chemistry, size distribution and the sintering process parameters. The flame front speed (bed permeability) has been considered as one of the important operating parameters and it mainly depends on the feed size of the sinter. In present work, pot grate sintering tests and plant trials have been carried out with different size distribution of sinter feed to understand the influence of feed size on productivity, and physical properties of the sinter. Sinter productivity increased with increase in feed mean particle size due to increased flame front speed and improved bed permeability with lower sintering time. With optimized moisture and same granulation condition, sinter with feed mean particle size of 3.2 mm (50 wt% over No. 6 mesh) and less fines (less than 10% below No. 60 mesh) yielded better sinter strength with lower return fines (–1/4 inch). |
