An indexable separator screen for use with a rotatable centrifugal separator device in which the screen is adapted to be moved relative to the bowl so that one or more wear areas on the screen can be moved from at least a first position to a second position relative to the bowl.
Claims8
The method of reducing wear on the surface of a screen used in a centrifugal separator device which device comprises a rotatable bowl having one or more blade assemblies fixed in an rotatable with said bowl said blade assemblies having a blade having a leading surface and
- a screen releasably attached to the top of said bowl, according to the steps of:
- (a) assessing said screen for wear on the surface of said screen;
- (b) disconnecting said screen from said separator bowl;
- (c) moving said screen relative to said bowl so as to move a wear area on said screen surface from at least a first position to a second position relative to said bowl where the wear area of said screen is spaced away from said blade;
- and,
- (d) releasably connecting said screen to said bowl whereby said screen is fixed to and rotatable with said bowl at said second position.
The method of increasing the wear life of a screen used in a centrifugal parts separator wherein said separator comprises;
- a rotatable separator bowl disposed within said separator, the bowl including a bottom wall and an inclined vertical wall;
- means for rotating said bowl;
- at least one blade assembly disposed within said bowl, said blade assembly including a blade positioned along at least said inclined bowl wall;
- a separator screen releasably joined to said rotatable bowl and adapted to rotate with said bowl;
- said method comprising the steps of:
- (a) assessing said screen for a worn area in the region of the screen located contiguous to said blade;
- (b) releasing the screen from said bowl whereby said screen is adapted to be moved from a first position where said worn area of the screen is contiguous with said blade;
- (c) moving said screen to a second position where the worn area of the screen is spaced away from said blade and,
- (d) releasably fastening said screen to said bowl when said screen is in said second position.
