Abstract

Provided below the funnel-shaped outlet opening of a receptacle filled with wet slag sand is an outlet funnel which is closed to begin with and forms a conical annular gap around the receptacle.
This gap fills with slag sand, as a result of which dewatering occurs according to the principle of the siphon effect.
