Twin Screw Granulation is the material through the feed port into the conveying area, spiral along the axial conveying to the mixing area, through the pinch disk exerted by the strong shear mechanical action, all the materials mixed evenly, compaction, and crushing a part of the large material mass, and then conveying the material to the shear area, knocking toothed disk again mixing and crushing, and through the die mouth molding, to obtain the particles in line with the requirements. Twin-screw extrusion granulation can shorten the production cycle, improve production efficiency, save manpower, materials and floor space, with high degree of automation and closure, product quality consistency and other advantages, can realize continuous production.
