Det beskrives en fremgangsmåte for å anbringe en siktsammenstilling på en siktmonteringsstruktur til en vibreringsseparator for effektivt å forsegle siktsammenstillingen på plass, der fremgangsmåten i visse aspekter innbefatter å anbringe siktsammenstillingen på en siktmonteringsstruktur på separatoren, og posisjonere siktsammenstillingen slik at tverrelementene til en firesidet hovedsakelig rektangulær støtte for siktsammenstillingen alle enten er parallelle med eller på tvers av materialflyten tvers over siktsammenstillingen, noe som tvinger to sider av støtten til siktsammenstillingen nedover med en kroningsapparatur for å forårsake kroning av siktsammenstillingen, der støtten er tilstrekkelig fleksibel slik at to sider av den unntatt de to nedtvungne sidene forseglende kontakter en overflate på siktsammenstillingen langs det vesentlige av deres lengde. Disclosed is a method for positioning a screen assembly on a screen mounting structure for a vibreringsseparator to effectively seal the screen assembly in place, the method in certain aspects includes placing the screen assembly on a screen mounting structure of the separator, and positioning the screen assembly such that the cross members to a four sided generally rectangular support for screen assembly all are either parallel to or across the flow of material across the screen assembly, forcing the two sides of the support for the screen assembly down with a kroningsapparatur to cause crowning of the screen assembly, where the support is sufficiently flexible so that two sides thereof except the two nedtvungne sides sealingly contacting a surface of the screen assembly along substantially their length.
