Pellet-Sinter composite agglomerate (P-SCA) is a mass containing acid pellet and basic sinter. In this study, the green pellets (10-15 mm), made up of Noamundi iron ore fines (2150 Blaine No) were mixed with a basic sinter mix of same ore of coarser size (-10 mm). A good quality P-SCA with 27% RDI, 91% shatter index and 70% RI could be …

Smelting of high-carbon ferrochrome from chromium agglomerate produced
In a test melts, high-carbon ferrochrome is produced from chrome sinter and chrome-ore fines in an arc electrofurnace. Two types of sinter with the best performance—the best sintering rate, strength, and product yield—are studied. It is demonstrated by experimental melts that high-carbon ferrochrome can be produced …

A major deterrent to the use of these catalysts, however, is that under reaction temperatures and pressures, the clusters tend to sinter, or agglomerate, leading to a dramatic decrease in activity. In an attempt to make these highly active Au catalysts more stable, mixed-oxide supports have been developed by substituting Ti atoms for Si in a ...

Aggregate Morphology Evolution by Sintering: Number
The mobility-equivalent agglomerate diameter in the free molecular (Meakin, 1988) and transition regimes (Rogak et al., 1993) is the diameter of a sphere having the equivalent projected area as the agglomerate. Additionally agglomerate structure is described by power laws between its characteristic size and mass or number of its primary particles.

ever, how to agglomerate return fines of sinter is a problem because the return fines are comparatively coarse and thus are difficult to agglomerate directly. Furthermore, since the wettability of the return fines with water is poor in compari-son with that of iron ore, it is more difficult to agglomerate return fines of sinter than powder iron ...
