An apparatus (10) for the passage and conveyance of compressible material, the apparatus (10) comprising at least two arrays (14) of substantially parallel first screw conveyors (16) each arranged at an outlet (56) of a vessel (12) from which the material is to be conveyed such that the material is
An apparatus (10) for the passage and conveyance of compressible material, the apparatus (10) comprising at least two arrays (14) of substantially parallel first screw conveyors (16) each arranged at an outlet (56) of a vessel (12) from which the material is to be conveyed such that the material is conveyed to respective second screw conveyors (18) arranged in generally transverse relation thereto, wherein the material to be conveyed bears directly on the first screw conveyors (16) from above and does not bear directly on the second screw conveyors (18). A method for the passage and conveyance of compressible material is also described.

1. An apparatus for the passage and conveyance of compressible material, the apparatus comprising at least two arrays of substantially parallel first screw conveyors each arranged at an outlet of a vessel from which the material is to be conveyed such that the material is conveyed to respective second screw conveyors arranged in generally transverse relation thereto, wherein the material to be conveyed bears directly on the first screw conveyors from above and does not bear directly on the second screw conveyors. 2. An apparatus according to claim 1, wherein there are provided two arrays of first screw conveyors arranged to feed material to the respective second screw conveyors. 3. An apparatus according to claim 2, wherein the two arrays of first screw conveyors feed material in substantially opposite directions toward the respective second screw conveyors. 4. An apparatus according to claim 2, wherein the two arrays of first screw conveyors abut at a mid-point of the outlet of the vessel such that each array of first screw conveyors is exposed to about half of the material presenting at the outlet of the vessel. 5. An apparatus according to claim 1, wherein the first screw conveyors each comprise a tapered shaft about which is provided a single helical flight, the shaft tapering towards an outer end thereof. 6. An apparatus according to claim 5, wherein the flight terminates towards the outer end thereof, providing a bare outer portion of the shaft. 7. An apparatus according to claim 5, wherein the helical flight increases in pitch relative to the shaft as it progresses towards the outer end thereof. 8. An apparatus according to claim 5, wherein a partial flight of reverse orientation is provided about the shaft adjacent the outer end thereof. 9. An apparatus according to claim 1, wherein the first and second screw conveyors are sealed and able to withstand and operate at elevated fluid pressures. 10. An apparatus according to claim 1, wherein the vessel from which the material is to be conveyed has an upper portion of generally cylindrical form and a lower portion that is provided in the form of an inverted cone, whereby material therein is funnelled into the inverted cone and a circular outlet provided at a base thereof. 11. An apparatus according to claim 10, wherein the apparatus for the passage and conveyance of compressible material is provided at the base of the inverted cone of the vessel. 12. An apparatus according to claim 10, wherein the inverted cone of the lower portion of the vessel is such that an arched or radial stress field is formed therein, thereby reducing the load that may be transferred to the apparatus for the passage and conveyance of compressible material. 13. An apparatus according to claim 12, wherein the arched or radial stress field is formed with a radius that centres on an imagined central point of the inverted cone of the lower portion of the vessel. 14. An apparatus according to claim 10, wherein the lower portion of the vessel describes an angle of between about 12 to 20° to the vertical. 15. An apparatus according to claim 10, wherein the lower portion of the vessel describes an angle of about 15° to the vertical. 16. An apparatus according to claim 1, wherein the arrays of first screw conveyors are provided in a housing, the housing allowing the material bearing thereon to flow radially into it across the arrays. 17. An apparatus according to claim 1, wherein the screw conveyors have associated therewith one or more screen means by which the material being conveyed is dewatered. 18. An apparatus according to claim 17, wherein each second screw conveyor has associated therewith a screen means by which the material being conveyed is dewatered. 19. An apparatus according to claim 18, wherein the screen means is provided in the form of a 180° screen. 20. An apparatus according to claim 19, wherein each second screw conveyor has associated therewith a further screen means by which the material being conveyed is further dewatered. 21. An apparatus according to claim 20, wherein each further screen means is provided in the form of a 360° screen, each being positioned within a dewatering housing. 22. An apparatus according to claim 21, wherein the dewatering housings are positioned at an end of the second screw conveyors to which the material is conveyed. 23. An apparatus according to claim 21, wherein the dewatering housing, housings for each of the first screw conveyors and second screw conveyors, and any inspection hatches provided thereon are sealed and able to withstand substantial internal fluid pressures. 24. A method for the passage and conveyance of compressible material, the method comprising the method steps of conveying that material bearing on at least two arrays of first screw conveyors, each array of first screw conveyors conveying laterally to a respective second screw conveyor arranged in transverse relation to its respective array of first screw conveyors, whereby the material does not bear directly on the respective second screw conveyors. 25. A method according to claim 24, wherein the material is conveyed by two arrays of first screw conveyors in substantially opposite directions toward the respective second screw conveyors. 26. A method according to claim 24, wherein the material being conveyed is dewatered as it is conveyed by the second screw conveyors. 27. A method according to claim 26, wherein the dewatering is effected by one or more screen means.
