Abstract

L'invention a pour objet un tamis pour essoreuse centrifuge à panier conique dont la surface est divisée en plusieurs secteurs. Ce tamis est caractérisé en ce qu'il est divisé par des cercles concentriques en zones successives dont les perforations sont différentes et comporte, en allant de sa petite base vers sa grande base, une première zone percée de trous ronds et à faible pourcentage de vide et plusieurs zones percées de fentes dont l'inclinaison croît dans chaque secteur de la petite base vers la grande base. L'invention est applicable aux essoreuses centrifuges utilisées pour l'essorage et le lavage de suspensions cristallines et notamment en sucrerie pour l'affinage poussé du sucre.The subject of the invention is a sieve for a centrifugal wringer with a conical basket, the surface of which is divided into several sectors. This sieve is characterized in that it is divided by concentric circles into successive zones the perforations of which are different and comprises, going from its small base to its large base, a first zone pierced with round holes and with a low percentage of void. and several zones pierced with slits the inclination of which increases in each sector from the small base to the large base. The invention is applicable to centrifugal dryers used for the drying and washing of crystalline suspensions and in particular in the sugar industry for the extensive refining of sugar.
