Abstract
Machine pour le compactage de matériaux solides comprenant au moins une paire de cylindres (1,2) creux côte à côte contre-roulants et engagés au moyen de dentures hélicoïdales respectives (10,20), en correspondance de la zone de prise (Z) des dentures (10,20) par effet de la rotation en direction opposée des cylindres (1,2) autour aux axes respectifs (a-a): chacun desdits cylindres étant pourvu, en correspondance des gorges (6) délimitées par les dentures (10,20), d'une pluralité de trous passants aptes à delimiter des canaux correspondants (100) à travers lesquels les matériaux à façonner sont obligés à passer par effet de la compression exercée par les dents (10,20) en prenant la forme de barrettes cylindriques (B) de section fondamentalement correspondante à celle de sortie des canaux (100) et orientées vers la cavité (CA) intérieure des cylindres (1,2). Machine for compacting solid materials comprising at least one pair of counter-rolling hollow cylinders (1,2) side by side and engaged by means of respective helical teeth (10,20), in correspondence with the gripping area (Z) teeth (10,20) by the effect of the rotation in opposite direction of the cylinders (1,2) around the respective axes (aa): each of said cylinders being provided, in correspondence with the grooves (6) delimited by the teeth (10, 20), a plurality of through holes capable of delimiting corresponding channels (100) through which the materials to be shaped are forced to pass by the effect of the compression exerted by the teeth (10,20) in the form of bars cylindrical (B) with a cross section basically corresponding to that of the outlet from the channels (100) and oriented towards the interior cavity (CA) of the cylinders (1,2).
