Abstract

An improved method of wet pelleting a powder material comprising wetting a powdered material with a pelleting amount of a liquid pelleting means, stirring the resulting mass of wet powder into an elongated pelletizing zone having: two trees rotationally extending axially through said zone, a multiplicity of agitator members fixed at spaced intervals along the entire length of each shaft and extending radially outwardly therefrom, moving the agitator members of each tree to and out of interdigitated relationship with the agitator members of the other shaft when both shafts rotate, a wall that limits the longitudinal periphery of said zone and which is close to the ends of the tips of the agitator members that are outside an interdigitated relationship, a dust inlet towards a end of said area and a nodule exit, towards the other end of the same, spin rapidly said trees and thus agitate, and pelletize, the powder moistened in said mass while the mass is also advanced axially, through the pelletising zone, to swirl said mass of powder against said wall of the zone of pelletizing, and moving the agitator members that are out of interdigitated relationship through the powder mass, against said wall, then cutting through said mass, by the movement of the agitator members that are in an interdigitated relationship, and repeatedly circulating the wet powder of said mass from said wall of the pelletizing zone, through the spaces between the interdigitated members, and back to the wall, as the powder mass advances axially towards said outlet of the pellet. Zone. (Machine-translation by Google Translate, not legally binding)
