Abstract

RESUMEN Se proporcionan métodos y aparatos para cribado. Las modalidades incluyen un aparato de cesta de cribado para un material de cribado, que comprende un estructura de rejilla que tiene una pluralidad de aberturas dispuestas en una cuadricula y una pluralidad de ensambles de cartucho de cribado fijas a la estructura de rejilla para cubrir las aberturas respectivas de la estructura de rejilla. El ensamble de cartucho de cribado incluye una caja y un ensamble de cribado fijo en la caja, y se puede fijar a un ensamble de miembro transversal del marco de rejilla. La caja se puede formar de una pieza moldeada por inyección individual integralmente formada por moldeo por inyección de uno de un poliuretano o un polímero termoendurecible. Los elementos de cribado forman conjuntamente una superficie de cribado generalmente continua a través del exterior de la estructura de rejilla, lo que reduce el cegamiento y es resistente al desgaste y desgarramiento.SUMMARY Methods and apparatus for screening are provided. The embodiments include a screening basket apparatus for a screening material, comprising a screen structure having a plurality of openings arranged in a grid and a plurality of screen cartridge assemblies fixed to the screen structure to cover the openings. respective of the grid structure. The screen cartridge assembly includes a box and a screen assembly fixed in the box, and can be attached to a cross member assembly of the screen frame. The box can be formed from a single injection molded part integrally formed by injection molding one of a polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across the outside of the grid structure, which reduces blinding and is resistant to wear and tear.
