Process for manufacturing a sifting device (or strainer baskets) for use in, e.g., in the paper industry for sorting and/or filtering fiber pulp suspensions. Sorter slits may be created between a plurality of substantially parallel rods inserted into respective insets formed in a support element. The rods may be securely held in place by first inserting the rods into the insets and then by permanently bonding the placement of the rods in the support elements with a bonding agent, e.g., as hard-soldering or brazing.

The invention concerns a rotor with impulse elements running in the vicinity of a rotationally symmetric screen basket and with blade elements which are run radially within the impulse elements with or by the rotor, notably for use in screen graders. The invention is characterized in that a pump impeller is formed by the mutual coordination and design of the blade elements.

A flotation cell with at least one injector for introducing a fluid and aspirating air therethrough has a multi-hole aperture plate. Premixing tube sections are disposed in the injector downstream from the aperture plate at a distance from the plate of at least 0.1 times the diameter of a hole in the aperture plate. The tube sections are oriented perpendicular to the aperture plate and open into a mixing tube.
