Abstract: A biomass granulator is described herein. In some embodiments, in the biomass granulator, the primarily molded particles extruded from the ring-shaped die are subjected to an orderly, quantitative and uniform reformation via a rotating scraper provided, as well as timely delivery of the finally molded particles out of the biomass granulator.

Abstract: A biomass granulator comprises a granulation chamber having a feed inlet and a discharge outlet and divided into a primary molding chamber, inside with a pressing wheel mechanism comprising a wheel seat having at least two symmetrical eccentric pressing rollers, and a secondary molding chamber, surrounding the outside of the primary one, by a ring-shaped die; the rollers are disposed with threads on the surface and a guide groove between adjacent threads; the die is provided outside with several scrapers taking the axis of the main shaft as the rotation axis, and the contact point of the roller and the is always between adjacent scrapers. The invention allows the primarily molded particles extruded from the die to be subjected to an orderly, quantitative and uniform reformation via a rotating scraper, and timely delivery of the finally molded particles out of the biomass granulator, thus solving the technical problems herein.
