Abstract

LA INVENCION SE REFIERE A UNA CRIBA ROTATORIA RECTANGULAR O CUADRADA (17), LA CUAL PRESENTA UNA GRAN CANTIDAD DE PILAS DE CRIBAS (16), CON, POR EJEMPLO, HASTA 20 CAJAS DE CRIBAS (1). SE PROPONE FORMAR LOS BASTIDORES DE LA CRIBA (3) SIN PARRILLA PORTANTE Y DISEÑADOS DE TAL FORMA QUE SEAN INTERCAMBIABLES EN ESTADO TENSADO Y COLOCADOS DENTRO O SOBRE LAS CAJAS DE CRIBAS (1). POR ELLO SE FORMA ENTRE EL TEJIDO DE LA CRIBA (10) ASI COMO UNA PLACA DEL SUELO PLANA (4), UN ESPACIO ABIERTO (11) PARA PERMITIR QUE EL MATERIAL CRIBADO CAIGA A TRAVES O SEA DESCARGADO. LOS LIMPIADORES DE LA CRIBA (6,6'') SE COLOCAN SOBRE LA PLACA DEL SUELO PLANA (4). EN UNA REALIZACION PARTICULARMENTE PREFERIDA, SE FORMAN LOS BASTIDORES DE LA CRIBA (3) COMO MARCOS DE METAL. LOS LIMPIADORES DE LA CRIBA (6,6'') LIMPIAN EL TEJIDO DE LA CRIBA (10) Y EVACUAN EL PRODUCTO DE LA PLACA DEL SUELO PLANA (4), PAA LO CUAL SE PROPONEN FORMAS DE 2, DE 3 O DE 4 BRAZOS.
