<p>A dry non-coherent powder having latent hydraulic binding properties is produced by wet grinding granulated blast furnace slag in a mill, continuously discharging the paste produced to a centrifugal atomizer which projects the paste as a spray into an enclosure through which hot gases are passed at a temperature high enough to dry instantaneously the particles of the paste. Specified temperature is between 300 DEG C. and 500 DEG C.</p> |
