Abstract

Un tamiz mecánicamente limpiable destinado a separar virutas, grumos y pulpa del líquido de circulación durante la producción de pasta química o pasta papelera por un método continuo, caracterizado porque el tamiz comprende dos elementos de tamiz independientes dispuestos en un bastidor (3) uno tras otro en la dirección de flujo del líquido a filtrar, un tamiz primario de filtrado (1) y un tamiz secundario (2) que limpia el tamiz primario.
