Abstract

A method for preparing raw material in the production of paper, board or fibreboards comprises processing raw materials to an aqueous fiber suspension that is subsequently grinded in a mill. Nitrogen is added to the raw material and/or the fiber suspension in supercooled form before the grinding process. The raw material and/or the fiber suspension are locally cooled by the addition of nitrogen and subsequently subjected at above 0º C. Waste paper is used as raw material and the nitrogen is added to the waste paper before the preparation of the fiber suspension for better removability of printing inks. A device for processing of raw materials for the production of paper, cardboard or fiber plates is disclosed.
