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 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, and, (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, (e) the axis of said outlet being substantially vertical, said outlet being defined by a downwardly and inwardly tapering wall which has portions horizontally displaced from and surrounding said obstruction means, (f) the means producing relative movement between the obstruction means and the lower portion of the vessel producing relative movement at a frequency of from 400 to 1000 cycles per minute, (g) the means vibrating said obstruction means producing vibrations in the range of 5,000 to 12,000 cycles per minute.

2. Apparatus according to claim 1 having mutually independent means for varying the frequency of the means vibrating the obstruction means and the means producing relative movement.

3. Apparatus according to claim 1 in which said obstruction means has an upper surface which is sloped downwardly and outwardly.

4. Apparatus for discharging solid materials, comprising: (a) a vessel having a lower portion with an outlet through which materials are discharged, (b) an obstruction means located within the lower portion of the vessel and spaced horizontally from the walls thereof to obstruct partially the flow of material through the outlet, said obstruction means being symmetrical about its central axis, (c) means for rotating said obstruction means about an axis spaced from and substantially parallel to said central axis, and (d) means vibrating said obstruction means in directions having components axially aligned with said outlet at a given frequency.

5. Apparatus according to claim 4 in which said given frequency is greater than the frequency of rotation of said obstruction means.

6. Apparatus according to claim 4 in which said given frequency is from 5, 000 to 12, 000 cycles per minute.

7. Apparatus according to claim 6 in which said obstruction means rotates at a frequency of from 400 to 1000 revolutions per minute.

8. Apparatus according to claim 7 having mutually independent means for varying said given frequency and the frequency of rotation.
