EVERYTHING YOU NEED TO KNOW ABOUT .

Kiln feeds with a high liquid phase (easy-burning mixes) have a high content of fluxes: the iron, alu­mina, magnesia, and alkalies. On the other hand, hard-burning mixes (low in iron, alumina, magnesia, and alkalies, and high in silica and lime) donot have a favo able influence on coating formation. Alkalies entrained in the gas stream promote ...
