Stirrer, comprising a spindle (1) provided with a drive, to which spindle a disc or plate (2) is affixed, cut into star-shape and extending perpendicular to the axis, to which, on one or both sides of said disc or plate a plurality of stirring blades (4) is affixed, lying substantially in radially d
Stirrer, comprising a spindle (1) provided with a drive, to which spindle a disc or plate (2) is affixed, cut into star-shape and extending perpendicular to the axis, to which, on one or both sides of said disc or plate a plurality of stirring blades (4) is affixed, lying substantially in radially directed axial planes and having the form of substantially right-angled triangles having the longer base directed radially and the shorter perpendicular, parallel to the axis, lying as the extreme edge at the greatest distance from the axis, where moreover the number of stirring blades on one disc side amounts to at least 8, the height (h) of the extreme blade edge is equal to 0.5 to 2 times the perpendicular distance (a) of the extreme end of one blade to the successive blade, and the length (L) of the blades, measured along their hypothenuse, amounts to at least twice the height (h) thereof. Preferably the number of blades on one disc side amounts to 12 or even 18. It is advantageous when the height (h) of the extreme edge of the blades amounts to 0.8 to 1.25 times the said perpendicular distance (a), and when the height of the extreme edge of blades is substantially equal to the said perpendicular distance.
