Abstract
A feed apparatus (10, 90, 160) for introducing particulate material into a fluid conduit includes a particulate material feed member (12) having first and second planar sides (16, 18) spaced apart laterally from one another and a row of material accommodating pockets (14) formed in the feed member (12). Each pocket (14) is in the form of a tube having open opposed ends, one of said open opposed ends being located in the first said planar side (16) of t he feed member (12) and the other of said open opposed ends being located in th e second planar side (18) of the feed member (12). A fluid inlet port (46) is opposed to said first planar side (16) and a fluid outlet port (48) is oppos ed to said second planar side (18). The inlet and outlet ports (46, 48) are located in alignment with one another and said row of pockets (14) such that the inlet and outlet ports (46, 48) are in fluid communication with one another via one or more of said pockets (14). An oversize material discharge port is opposed to said second planar side (18) and a mineral reducer (98) i s located between the oversize material discharge port and an input into the feed member (12). The feed member (12) is movably mounted in a direction parallel to the planes containing said planar sides (16, 18) to move successive pockets (14)in said row from a material deposit location (ML), into registry between said inlet and outlet ports (46, 48) to discharge material up to a predetermined size through said fluid outlet port (48), and to said oversize material discharge port to discharge material in excess of said predetermined size, to said mineral reducer (98), through said oversize material discharge port.
Claims (22)
1. A feed apparatus for introducing particulate material into a fluid conduit, the apparatus including:
a particulate material feed member having first and second planar sides spaced apart laterally from one another and a row of material accommodating pockets formed in the feed member, each pocket being in the form of a tube having open opposed ends, one of said open opposed ends being located in the first said planar side of the feed member and the other of said open opposed ends being located in the second planar side of the feed member;
a fluid inlet port opposed to said first planar side and a fluid outlet port opposed to said second planar side, the inlet and outlet ports being located in alignment with one another and said row of pockets such that the inlet and outlet ports are in fluid communication with one another via one or more of said pockets;
an oversize material discharge port opposed to said second planar side;
and a mineral reducer located between the oversize material discharge port and an input into the feed member, said feed member being movably mounted in a direction parallel to the planes containing said planar sides to move successive pockets in said row from a material deposit location, into registry between said inlet and outlet ports to discharge material up to a predetermined size through said fluid outlet port, and to said oversize material discharge port to discharge material in excess of said predetermined size, to said mineral reducer, through said oversize material discharge port.
a particulate material feed member having first and second planar sides spaced apart laterally from one another and a row of material accommodating pockets formed in the feed member, each pocket being in the form of a tube having open opposed ends, one of said open opposed ends being located in the first said planar side of the feed member and the other of said open opposed ends being located in the second planar side of the feed member;
a fluid inlet port opposed to said first planar side and a fluid outlet port opposed to said second planar side, the inlet and outlet ports being located in alignment with one another and said row of pockets such that the inlet and outlet ports are in fluid communication with one another via one or more of said pockets;
an oversize material discharge port opposed to said second planar side;
and a mineral reducer located between the oversize material discharge port and an input into the feed member, said feed member being movably mounted in a direction parallel to the planes containing said planar sides to move successive pockets in said row from a material deposit location, into registry between said inlet and outlet ports to discharge material up to a predetermined size through said fluid outlet port, and to said oversize material discharge port to discharge material in excess of said predetermined size, to said mineral reducer, through said oversize material discharge port.
2. A feed apparatus according to Claim 1 wherein the feed member is in the form of a disc which is rotatable about a central axis and said row of pockets is in the form of an annulus centred on said central axis.
3. A feed apparatus according to Claim 2 wherein said central axis is inclined, the disc being housed in a closed casing which is open only at an open-topped hopper communicating with said material deposit location.
4. A feed apparatus according to Claim 3 wherein said central axis inclined at an angle of 45° to the horizontal.
5. A feed apparatus according to Claim 2 or Claim 3 wherein said material deposit location partially overlaps with said oversize material discharge port to permit a portion of material being deposited at said material deposit location to discharge through said oversize material discharge port.
6. A feed apparatus according to any one of Claims 2 to 5 wherein opposed sides of each pocket are defined by radially extending vanes.
7. A feed apparatus according to Claim 6 wherein the vanes are inclined relative to said direction of movement of the feed member.
8. A feed apparatus according to any preceding claim including a fluid feed location for filling each pocket with fluid prior to the pocket moving into registry between said inlet and outlet ports.
9. A feed apparatus according to Claim 8 wherein said fluid feed location is positioned between said material deposit location and said inlet and outlet ports.
10. A feed apparatus according to Claim 8 wherein said fluid feed location coincides with said material deposit location.
11. A feed apparatus according to any one of Claims 8 to 10 wherein said fluid is heated to a temperature in the range of 40-70°C.
12. A feed apparatus according to any preceding claim wherein the outlet port is closed by a sizing grid which serves to retain said material in excess of said predetermined size within a pocket in registry with said inlet and outlet ports.
13. A feed apparatus according to any preceding claim wherein said oversize material discharge port defines a fluid outlet for excess fluid.
14. A feed apparatus according to Claim 13 further including a pump and return conduit between said mineral reducer and particulate material feed member to pump crushed material and fluid to said material deposit location.
15. A feed apparatus according to Claim 14 wherein said return conduit includes a discharge nozzle which discharges a jet of crushed material and fluid into an airborne stream of particulate material being delivered to said material deposit location.
16. A feed apparatus according to Claim 13 further including a pump and return conduit between said mineral reducer and particulate material feed member to pump crushed material and fluid to said fluid inlet port.
17. A feed apparatus according to any one of Claims 14 to 16 wherein said pump is a vaned centrifugal pump.
18. A feed apparatus according to any preceding claim wherein an outlet pump is located in close proximity to said fluid outlet port to create suction at said fluid outlet port, and said fluid inlet port is formed into a jet nozzle.
19. A feed apparatus according to Claim 18, when dependent on Claim 2, wherein said jet nozzle is in the form of a slot which extends radially relative to said disc.
20. A feed apparatus according to Claim 19 wherein the cross-sectional area of said slot is the same as the cross-sectional area of an inlet conduit of said fluid inlet port.
21. A feed apparatus according to any one of Claims 18 to 20 wherein said outlet pump is a vaned centrifugal pump.
22. A process for forming a slurry for conveying particulate material along a pipeline, the processing including mixing said particulate material with a conveying fluid using a feed apparatus according to any preceding claim to form said slurry and subsequently pumping said slurry along said pipeline.
