reactions. In this process, a mixture of iron ore fines, flux, and coal particles is heated to about 1300 C– 1480 C in a sinter bed. The strength and reducibility properties of iron ore sinter are obtained by liquid phase sintering. The silico-ferrite of calcium and aluminum (SFCA) is the main bonding phase found in modern iron ore sinters.

Screening Theory and Practice
Allowable surface moisture for unimpaired dry screening of inorganic granular or pelletized particles ranges from bone dry for screen openings below 20 mesh, to 3% for 1/4" openings. Absorbed moisture in permeable soils such as ground clay can block the screen openings with cumulative buildups of extreme fines attached to the screen wires.

Dry and Wet Screening in Mining: What are the Differences?
February 14, 2018. If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you're missing several important points. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water. Extra plant capital is on the agenda when these ...

Screening Methods in Archaeology | SpringerLink
Screening methods have been part of the archaeological discourse for the last 60 years and focus on the analysis of the removed sediments in order to recover smaller artifacts, usually missed during excavation. The methodology varies and can be divided into dry screening (or sieving) and wet screening, implemented by water.
