Description: THE EMBODIMENT OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:

1. Apparatus for discharging solid materials, comprising: (a) a vessel having a lower portion with an outlet through which materials are discharged, (b) obstruction means located adjacent to the lower portion of the vessel in a position to obstruct partially the flow of material through said outlet, (c) means vibrating said obstruction means in directions having components axially aligned with said outlet at a given frequency, (d) means producing relative movement transverse to the axis of said outlet between said obstruction means and said lower portion of the vessel, which relative movement has a frequency less than said given frequency, and (e) means mounted on said obstruction means for introducing a flushing liquid into that portion of the vessel adjacent the obstruction means.

2. Apparatus according to claim 1 having means for rotating said obstruction means about a substantially vertical axis which is unequally spaced from peripheral portions of the obstruction means in order to produce the aforementioned relative movement.

3. Apparatus according to claim 1 in which the means vibrating said obstruction means produces vibrations in the range of 5,000 to 12,000 cycles per minute.

4. Apparatus according to claim 3 having means for varying the frequency of the means vibrating the obstruction means within the specified frequency range.

5. Apparatus for discharging solid particulate materials from a vessel containing liquid and solid particulate materials, said apparatus comprising: (a) a vessel having a lower portion with an outlet through which materials are discharged; (b) obstruction means located adjacent the lower portion of the vessel in a position to obstruct partially the flow of material through said outlet; (c) means vibrating said obstruction means in directions having axially aligned with said outlet at a given frequency, (d) means at said outlet for introducing flushing liquid into a zone adjacent said obstruction means, and (e) means producing relative movement transverse to the axis of said outlet between said obstruction means and the lower portion of the vessel, said relative movement having a frequency less than said given frequency.

6. Apparatus according to claim 5 in which said given frequency is from 5,000 to 12,000 cycles per minute.

7. Apparatus according to claim 6 in which the transverse movement of said obstruction means is at a frequency of from 400 to 1000 cycles per minute.
