A B S T R A C T The invention relates to a device for the production of mechanical pulpfrom a lignocellulose material, comprising a grinding disc (1) rotating round a shaft (2) running at right-angles through the centre of each end surface of the disc, and means (10-13) for holding and pressing one or more pieces of the material to be processed against one or both of these end surfaces, which are given the form of grinding surfaces, the fibres of the material to be processed being essentially oriented in the plane of the grinding surface, and water, which may contain chemicals, being introduced during the grinding-process. The grinding disc is enclosed in a housing (5) kept at above-atmospheric pressure. The means for holding the material to be processed is so designed as to hold the pieces of such material with their fibres largely pointing in a direction outwards from the centre of the grinding device. The means (7) for introducing water into the grinder is so designed as to carry water to the centre of the grinding device.
