Abstract: 1. A washing liquid distribution system for distributing liquid to a plurality of flights of a separator comprising a liquid flow distributor including a housing which receives fluid therein to be distributed, a plurality of spaced members having a respective generally vertical passages communicating with fluid in said housing for permitting fluid to flow through said passages into said members, a plurality of fluid passageways respectively communicating with said members to provide the same or differing amounts of liquid to each of said flights. 2. The system of Claim 1 wherein said housing includes a central liquid receiving chamber, and wherein said members include a plurality of spaced compartments located in proximity with said chamber and said plurality of generally vertical passages communicate fluidly between said chamber and said compartments, said plurality of passageways including a plurality of pipes respectively coupled to said compartments, each of said compartments delivering the same or differing amounts of liquid to each of said pipes. 3. The system of Claim 2 wherein said housing includes a movable flow controller disposed inside said chamber to vary liquid flow to each of said compartments when said flow controller moves from one position to another. 4. The system of Claim 3 wherein said controller having a slanted upper edge and having cylindrical shape substantially conforming to said chamber, said chamber being rotatable therein to expose different portions of said passages at every rotation thereby varying the liquid flow to each of said compartments. 5. The system of Claim 1 wherein said passages are substantially vertical, and further including a tilting means for slanting said distributor from horizontal to vary exposed areas of said passages thereby varying the amount of liquid flowing into said compartments. 6. The system of Claim 1 wherein said housing is elongated, and further including a rotatable cam disposed underneath one end of said housing and a hinge joint disposed underneath another end of said housing, said cam being rotatable for changing slope of said housing to change exposed areas of said passages to liquid in said chamber thereby varying amounts of liquid flowing through said passages into said compartments. 7. The system of Claim 1 further including a liquid supply providing liquid to said housing, a control mechanism for controlling flow of liquid flowing inside said members, and a stream analyzer for analyzing composition of a stream of particles traveling through a spiral separator. 8. The system of Claim 1 wherein said plurality of fluid passageways being disposed about a support column and pass through openings in the support column to deliver a washing liquid therefrom, said system further including a dampening receiver disposed about the support column and adapted to receive washing liquid from said plurality of fluid passageways to dampen energy of the liquid and deliver the liquid adjacent an inner side of a flight in a spiral separator. 9. The system of Claim 8 further including a plurality of dampening receivers disposed directly opposite from each other about the support column. 10. The system of Claim 1 wherein said members include a plurality of spaced pipes disposed vertically inside said housing and having a height less than that of said housing, said pipes having respective passages for receiving liquid from said housing into said pipe, and said system further including means for tilting said housing to vary liquid flow through said passages thereby changing amounts of liquid flowing to said plurality of flights. 11. The system of Claim 1 wherein said passages are elongated. 12. The system of Claim 1 wherein said passages are elliptical. 13 The system of Claim 1 wherein said passages are V-shaped narrowing toward a bottom of said housing. 14. A washing liquid distribution system comprising a distributor housing, a central chamber, a plurality of compartments located in proximity with said chamber and having a plurality of passages having an elongated axis extending generally vertically communicating fluidly with said chamber, a plurality of fluid passageways respectively coupled to said compartments, means for simultaneously varying flow of liquid to each of said fluid passages for delivering the same or differing amounts of liquid to each of said fluid passageways. 15. The system of Claim 14 wherein said means include a hinge joint disposed underneath one end of said distributor and a tilting member disposed underneath another end of said distributor for tilting said distributor and to vary exposed areas of said passages to liquid thereby varying amounts of liquid flowing to each of said fluid passageways. 16. The system of Claim 14 wherein said means include an elongated cam disposed underneath one end of said distributor, a hinge joint disposed underneath another end of said distributor, said cam being rotatable from one position to another to vary exposed areas of said passages to liquid in said chamber thereby varying amounts of liquid flowing to each of said fluid passageways. 17. The system of Claim 14 further including a liquid supply providing liquid to said distributor, a control mechanism for controlling flow to said fluid passageways, a stream analyzer for analyzing a composition of a stream of particles traveling through a spiral separator. 18. The system of Claim 14 wherein said plurality of fluid passageways being disposed within a support column and pass though openings in said support column to deliver washing liquid therefrom, said system further including dampening receivers spatially disposed about the support column to receive liquid from said plurality of fluid passageways to dampen energy of the liquid and deliver it adjacent an inner side of a trough surface of a flight in a spiral separator. 19. A washing liquid distribution system comprising a distributor having a central chamber, a plurality of hollow members in proximity with said chamber and having a plurality of passages communicating fluidly with said chamber, a plurality of fluid passageways coupled to respective said members, each of said compartments having an outlet communicating fluidly with said fluid passageways, and a flow controller movable from one position to another for exposing different portions of said passages in each of said positions of said controller thereby varying amounts of liquid flowing into each of said members and into each of said fluid passageways. 20. The system of Claim 19 wherein said chamber having cylindrical shape, said controller being cylindrical in shape substantially conforming to said chamber and being disposed inside it, said controller having a slanted upper edge exposing different portions of said passages in each of said positions thereby varying amounts of liquid flowing into each of said members. 21. The system of Claim 19 wherein said controller includes a tilting member disposed underneath said distributor for tilting said distributor to change exposed areas of said passages thereby varying amounts of liquid flowing to said members. 22. The system of Claim 19 wherein said distributor is elongated, said controller including a longitudinal rotatable cam disposed underneath one end of said distributor, a hinge joint disposed underneath another end of said distributor, said cam being rotatable for changing slope of said distributor to change exposed areas of said passages to liquid thereby varying amounts of liquid flowing therefrom. 23. The system of Claim 19 further including a plurality of receivers disposed around a support column of a spiral separator to receive washing liquid from said fluid passageways and deliver liquid to a trough surface of a flight in the separator. 24. The system of Claim 19 further including a plurality of spiral separators having a plurality of flights, said distributor distributes differing amounts of liquid to each flight of a spiral separator. 25. The system of Claim 19 further including a spiral separator for separating heavier particle concentrations from lighter particles and having a plurality of flights, said controller delivers differing amounts of washing liquid to each flight for enhancing efficiency of separation of the separator.
