Briquetting Article about Briquetting by The Free Dictionary

Briquetting was widely used in the second half of the 19th century to nodulize ore fines. The mechanism of the principal stage of briquetting—compressing of the raw material into the desired shape—may be described as follows. At low pressures there is an external compacting of the material caused by reduction of the spaces between particles.

iron ore burden is such that the ascending column of g ases interfaces with the maximum surface area of the iron ore - the higher the content of iron ore fines in the feedstock, the lower the permeability of the burden. The iron ore feedstock (pellets and lump ore) is therefore screened to remove fines before being charged to the furnace.
