Abstract (en)
[origin: EP0342457A2] Apparatus and method for manufacturing impervious mineral materials, in particular from clay or similar cohesive materials for a surface seal, in which soft to very hard cohesive impervious materials, possibly in large-clod form, are continuously manufactured in a system which comprises a charging box (12), a roller-type crusher (19) and a double-shaft mixer (23) with pressure zone and shredding mechanism for kneading the cohesive materials and other constituents and subsequently granulate this sealing compound. Using the apparatus and the method, cohesive sealing compounds of the most widely varying consistency can be manufactured in a manner such that seals can be produced therefrom which are impervious even to waters polluted with noxious substances even over a prolonged period. <IMAGE>
