Abstract

A vibratory separator comprising a basket (12) having screening apparatus (30) mounted therein, the screening apparatus having at least a first portion (32) and a second portion (31), the first portion (32) lower in the basket than the second portion (31). A method for screening material comprising the steps of introducing material to be screened into a basket of a vibratory separator, said material landing on a screen having a first portion and a second portion, the first portion at a lower height in the basket than the second portion.

Claims (27)

1. A vibratory separator comprising a basket (12) having screening apparatus (30) mounted therein, the screening apparatus having at least a first portion (32) and a second portion (31), the first portion (32) lower in the basket than the second portion (31).
2. A vibratory separator as claimed in Claim 1, wherein said screening apparatus is a single screen.
3. A vibratory separator as claimed in Claim 1 or 2, further comprising a collection receptacle below the screening apparatus for receiving material components flowing through the screening apparatus.
4. A vibratory separator as claimed in Claim 1, 2 or 3, wherein said basket (12) has two sides (13,15) spaced-apart by a first end (16) at which the material is introduced into the basket (12) and a second end spaced-apart from the first end (16), wherein in use, components separated from material being separated exit the basket from the second end.
5. A vibratory separator as claimed in Claim 1, 2, 3 or 4, vibrating apparatus (14) connected to the basket (12) for vibrating the basket.
6. A vibratory separator as claimed in Claim 1 to 5, wherein said first portion (32) is at the first end (16) of the basket (12).
7. A vibratory separator as claimed in any preceding Claim, wherein said first end (16) of the basket (12) and parts of the two spaced-apart sides (13,15) define a space in which a pool of the material is formable above the first portion (32) of the screening apparatus.
8. A vibratory separator as claimed in any preceding Claim, further comprising a third portion (33) lower in the basket (12) than the second portion (31).
9. A vibratory separator as claimed in any preceding Claim, further comprising wherein the basket (42) has an exit end spaced apart from the first end (46), the basket (42) further comprising a secondary screen (60;73) located at the exit end, the secondary screen (60;73) having a portion thereof disposed beneath the exit end of the screening apparatus so that material components flow from the screening apparatus onto the secondary screen.
10. A vibratory separator as claimed in Claim 9, wherein the secondary screen (60) is a substantially flat screen.
11. A vibratory separator as claimed in Claim 9, wherein the secondary screen (73) is a curved screen viewed from the side.
12. A vibratory separator as claimed in any preceding Claim, wherein the screening apparatus is curved (30;72;125) when viewed from the side.
13. A vibratory separator as claimed in any preceding Claim, wherein, in use a pool of material (22;59;69;122) forms above the first portion (32;52;72b;123) of the screening apparatus.
14. A vibratory separator as claimed in Claim 13, wherein the pool of material (22;59;69;122) extends across the basket (12;42) from a first side (13;43)of the basket to a second side (15;45) of the basket at a first end (16) and at any distance from the first end has a substantially similar depth from the first side of the basket to the second side of the basket.
15. A vibratory separator as claimed in Claim 12, 13 or 14, wherein said basket has side walls and an end wall, at least one of which has screening material (142,154) therein, such that fluid and small particles can flow therethrough and into a collection receptacle.
16. A vibratory separator as claimed in Claim 15, wherein at least one of said side walls and end wall has an aperture therein, said aperture covered in said screening material.
17. A vibratory separator as claimed in Claim 16, wherein the aperture (152) is through the end wall.
18. A vibratory separator as claimed in Claim 16 or 17, Wherein the aperture (142) is through one of the two spaced-apart side walls.
19. A vibratory separator as claimed in any preceding Claim, further comprising apparatus (160-163) for maintaining height of a portion (72a) of the screening apparatus.
20. A vibratory separator as claimed in Claim 19, wherein the apparatus comprises an inflatable bladder (163).
21. A vibratory separator as claimed in Claim 20, Wherein the inflatable bladder (163) is selectively adjustable to adjust height of a portion (72a) of the screening apparatus.
22. A vibratory separator as claimed in Claim 21, further comprising control apparatus (60,61) to control adjustment of the inflatable bladder (163), and monitor apparatus (160,161) for monitoring height of a portion (72a) of the screening apparatus.
23. A vibratory separator as claimed in any preceding Claim, Wherein the screening apparatus is two-dimensional.
24. A vibratory separator as claimed in any preceding Claim, wherein the screening apparatus is three-dimensional.
25. A basket of the vibratory separator as claimed in any preceding claim.
26. A screen apparatus of the vibratory separator as claimed in any of claims 1 to 25.
27. A method for screening material comprising the steps of introducing material to be screened into a basket of a vibratory separator, said material landing on a screen having a first portion and a second portion, the first portion at a lower height in the basket than the second portion.
