ABSTRACT:
An arrangement for the production of vitrified slag includes a rotating cooling drum provided with an internal cooling and on whose surface molten-slag-receiving recesses are provided. The site of impact of the slag is approximately at the uppermost point of the cooling drum. In order to ensure the vitrification of the slag with the flowing of molten slag off the cooling drum being reliably prevented, and an economic production of solidified slag being ensured, the recesses are separated by webs in the circumferential direction of the cooling drum and in the end region of the cooling drum are designed to be closed in the axial direction thereof. A plurality of cooled counter rolls contacting the webs by their surfaces and aligned with their axes parallel to the cooling drum are provided. They are arranged after the site of impact of the slag in the rotation direction of the cooling drum and one behind the other in its circumferential direction.
