Abstract

Un aparato de cribado que incluye una sub-rejilla, y un elemento de criba acoplado a la sub-rejilla mediante soldadura láser en una pluralidad de posiciones de acoplamiento de manera tal que, bajo excitación vibracional, el elemento de criba tiene un perfil predeterminado de movimiento vibracional con respecto a la sub-rejilla. El elemento de criba se puede acoplar en un número máximo de posiciones de acoplamiento a la sub-rejilla para minimizar el movimiento relativo del elemento de criba y la sub-rejilla bajo excitación vibracional, o el elemento de criba se puede acoplar un sub-conjunto del número máximo de posiciones de acoplamiento para permitir el movimiento vibracional del elemento de criba con respecto a la sub-rejilla. Un método divulgado puede incluir acoplar una pluralidad de elementos de criba a una respectiva pluralidad de sub-rejillas, acoplar la pluralidad de sub-rejillas entre sí para formar un pre-montaje de cribado, y cortar los bordes del pre-montaje de cribado para formar el montaje de cribado teniendo un perímetro con una forma predeterminada.A screening apparatus including a sub-grid, and a screen element coupled to the sub-grid by laser welding at a plurality of mating positions such that, under vibrational excitation, the screen element has a predetermined profile of vibrational motion with respect to the sub-lattice. The screen element can be coupled in a maximum number of coupling positions to the sub-grid to minimize relative movement of the screen element and sub-grid under vibrational excitation, or the screen element can be coupled to a sub-assembly of the maximum number of coupling positions to allow vibrational movement of the screen element with respect to the sub-grid. A disclosed method may include coupling a plurality of screen elements to a respective plurality of sub-grids, coupling the plurality of sub-grids together to form a screen pre-assembly, and cutting the edges of the screen pre-assembly to forming the screening assembly having a perimeter with a predetermined shape.
