Abstract of the Disclosure Frame construction for a pressure grinding machine of press type, which frame construction comprises a gas- tight, pressure-proof grinding chamber, bearing housings for a grinder member revolving in the grinding chamber, as well as at least one press chamber for the pulpwood and a press device limiting the press chamber on one side. The frame construction consists of two separate parts, namely a pressure frame, which constitutes the said grin- ding chamber and press chamber and which substantially receives the pressure forces resulting from the positive pressure prevailing in the grinding chamber, and a power frame, which connects the press device and the bearing housings of the grindstone to each other and which sub- stantially receives the tensile and circumferential forces resulting from the grinding and from the pressing of the wood against the grindstone.
