  • Screen media element having ceramic sections with apertures
    Patent number: 8813975
    Abstract: A screen media element having at least one apertured section. The apertured section has a first surface intended to receive and carry material to be screened, a second surface opposite the first surface, apertures extending from the first surface to the second surface and a circumferential surface connecting the first and second surfaces. The apertured section is surrounded by an outer frame along the circumferential surface, characterized in that the apertured section is made from ceramic material and that the outer frame is made of elastomeric material. The invention further relates to a method for manufacturing such a screen media element, and a screen comprising such screen media elements.
