Abstract
A method for producing a screen body for a screen used in a screw press, which screen body comprises one or more openings on a screen surface, In order to achieve a particularly long service life, it is provided that the screen body is formed by a sintering process and/or an additive manufacturing process, in particular a 3D printing process. Further embodiments include a screen, in particular for a screw press, having a screen body which has openings on a screen surface.
Claims29
A method for producing a screen body for a screen used in a screw press, the screen body including one or more openings on a screen surface, the method comprising:
- forming the screen body is formed by a sintering process and/or an additive manufacturing process, and
- at least partially forming the screen body from a material which is dimensionally stable at a temperature of at least 45° C. and a pressure load of 1.5 N/mm2.
A screw press for separating liquid out of a transport material, comprising:
- a worm shaft together with a screw conveyor arranged helically on the worm shaft;
- a housing shell surrounding said conveyor,
- wherein a transport corridor for the transport material to be conveyed is embodied between the worm shaft and the housing shell, and
- wherein the housing shell comprises at least one screen that includes one or more openings on a screen surface and is composed of a material that is formed in a sintering process and/or an additive manufacturing process and which is at least partially formed from a material that is dimensionally stable at a temperature of at least 45° C. and a pressure load of 1.5 N/mm2, so that the liquid separated out of the transport material is conveyable through the housing shell.
