Opening chamber 14 is the piston slide 4 in the open position. The nozzle openings 8 can now lie below the recesses 9 and all, including those previously from the piston valve 4 closed recesses 9 are now in open connection with the outside space. At the same time When washing water is supplied, all solids are flushed out of the drum through the annular gap 16.

The drum according to FIG. 2 differs from that according to FIG. 1 essentially only in that during the movement of the piston valve 4 into its open position over the entire circumference of the concentrating space 10 extending annular gap between the piston valve 4 and drum cover 2 released will. The concentrate passing through this annular gap then passes through ejection slots 17 in the lower part of the drum 1 outdoors.

In this embodiment, the connection remains the inlet openings 8 of the nozzles 5 with the concentrating space 10 also in the open position of the piston valve exist.

The drum according to FIG. 3 is with several tubes evenly distributed around the circumference 18 equipped, which lead from the outer part of the concentrating space 10 to discharge nozzles 5, which in lesser Distance from the axis of rotation are arranged. The piston valve 4 is in a known manner

controlled by means of a control fluid, which in corresponding Quantities of the gutter 11 is supplied. In the closed position of the piston valve 4 the drum works as a nozzle drum. The concentrate is continuously discharged through the nozzles 5

ίο spins. Empty after blocking the inlet; the drum is up to the level line A, which is the same distance from the axis of rotation as the discharge bores of the nozzles 5. After moving the :: piston valve 4 into its open position, is there?

The concentrate remaining in the drum radially outside the level line A is ejected through the annular gap 16 created between the piston valve 4 and the sealing ring 7 and the ejection slots 17 in the lower drum part 1.

ao The drum according to the invention represents a new type of drum made of elements known per se., . During operation it works as a normal nozzle drum, but can be used without dismantling when it is full Speed completely emptied and cleaned.
