Abstract
To permit a continuous production of foamed blast furnace slag, a revolving conveyor is provided, which is continuously supplied with a stream of slag from a slag feeder in a trough which comprises a bottom and side walls rising from the bottom. Adjacent to the slag feeder, stationary tubular lances extend in said trough closely above the bottom in the direction of conveyance and are formed in a predetermined length portion with radial outlet orifices for a discharge of water into said trough.
