Abstract: A blank for a rotary tool for chip removing machining, such as a helix drill or an end mill is formed by advancing a mixture of hard metal powder and carrier through an extrusion passage. The mixture is fed past a core having pins secured thereto for forming respective internal holes through the mixture. Then the mixture is advanced through a rotary part that is rotating about a center axis of the extrusion passage, wherein the rotary part and the internal holes become twisted to a predetermined pitch. The mixture is also advanced past a plurality of shaping parts which project transversely into the extrusion passage for shaping exterior chip flutes in the mixture, e.g., by embossing or cutting. The mixture is allowed to harden into a green body, and the green body is then sintered to form a blank.

Abstract: The method is for separation of lignin from original black liquor (BLIN) and has the following phases in sequence. A first precipitation phase (PR1) for precipitation of lignin by a first acidification of the original black liquor by adding a first acid or mixture of acids (G1a) followed by a first storage phase wherein precipitated lignin particles are allowed to increase in size, followed by a second precipitation phase (PR2) for precipitation of lignin by a further acidification of the original black liquor by adding a second acid or mixture of acids (G1b). By retaining the acidified black liquor for at least 25 minutes in the storage phase are the precipitated lignin particles allowed to grow in size and the filterability is improved considerably.
