ABSTRACT:
A device for the simultaneous continuous feeding of pulverulent solids and of liquids into a treatment machine wherein the casing of the machine is provided with an orifice for feeding in liquids and solids. A feed branch extends upwardly from this orifice and leads into a ring passage. Positioned on the inner wall of the feed branch is an orifice for feeding liquids to the treatment machine and located in the center of the ring passage is a device for feeding solids to the treatment machine. The free cross-sectional size and shape of the orifice is adjustable and may be varied, in a simple manner, by modifications to the structures of the ring passage and orifices. In the cylindrical section of the feed branch several annular rows of bores, having differing diameters in each of the rows, form an orifice for the liquid feed. The bores within one row are arranged offset tangentially relatively to the direction of the adjacent bores in the other rows. The orifice may also comprise axially extending slots which are formed in the cylindrical section and which widen toward the base of the slots in the shape of a wedge. In another embodiment, an adjustable annular gap is provided between the upper and lower sections of the feed branch by means of a threaded connection provided between the upper and lower section parts. A clamping screw is provided to maintain any selected adjustment of the gap unchanged during any desired period of use of the treatment machine.
