Abstract

A method of producing a foundation bed (1) for a granulator mill includes the steps that the foundation bed is cast from a plastic- or concrete based casting material in a mold (13) manufactured from thin sheet metal, the mold being given surfaces (16) for cooperation with a granulator mill housing (2) with high precision. In order to avoid after-treatment of the surfaces (16) of the mold intended for cooperation with the granulator mill housing, these surfaces are clamped during the casting process against a common, configurationally stable clamping member.
