Abstract
The mixer tube for low viscosity fluids contains plate-shaped elements which at one or at several points of the tube partially cover or block off its cross-section. The constrictions left free through the elements each comprise at least one gap-shaped region, with a longitudinal extent of this gap extending from tube wall to tube wall through the tube axis or from the tube wall through the tube axis to a second partial region. The gap subtends an angle with the tube axis in the range between about 20.degree. and 60.degree., preferably between 35.degree. and 45.degree.. A mixing path is provided after the constriction in the direction of flow. The fluid to be mixed can contain solid substances in suspension.
