Abstract
Frame construction for a pressure grinding machine of press type, which frame construction comprises a gastight, 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 grinding 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 substantially receives the tensile and circumferential forces resulting from the grinding and from the pressing of the wood against the grindstone.
