Preparation Of Calcium Aluminate-Spinel Synthetic Aggregates Using Electrostatic Precipitated Dolomite DustAnd Calcined Alumina [PDF]

open access: yes, 2012
Calcium alumniate-spinel phases have been developed for synthetic aggregate from ESP dolomite dust and calcined alumina. A huge amount of dolomite dust is collected at electrostatic precipitator (ESP) during dead burning of raw dolomite in Rotary Kiln ...
