  • flax, hemp, sisal, jute and wood fibers are particularly suitable.
  • the granules according to the invention can contain up to 98% plant fibers, the binding of the plant fibers to one another being achievable via the additives contained. This means that particularly light granules can be obtained here.

  • a major advantage of the method according to the invention is entered in the further development according to claim 12, in which the starting mixtures used as plant parts do not have to be pretreated, but can be subjected to the method immediately in non-or even roughly comminuted form.
  • known additives such as dyes, adhesives, flame retardants, fillers and antibiotic agents can be added so that the granules obtained can be used directly, for example in an injection molding process. As a result, the finished products are created without further post-processing.
  • a pressing pressure is advantageously generated by the configurations according to FIG Claims 16 to 18 in connection with the formation of the press channels of the dies according to claim 30.
  • the method according to the invention advantageously allows the addition of thermoplastic substances both in the first granulation stage and before the second granulation stage to be made possible by the configuration according to claim 19.

  • a sawtooth profile is applied to the surface of the roller 208. The higher the proportion of plant fiber in the starting material, the steeper and deeper the flanks of the sawtooth profile are.

This clearly shows that a lower pressure builds up when the profiling is symmetrical and weak (FIG. 2, pressure curve la).

This granulate can now be removed for further processing. However, if the proportion of the plant constituents in the starting mixture is more than 60%, the quality of the granules produced with the pre-granulator 216 can be significantly improved by a downstream end granulator 211. The pre-granules are therefore transferred immediately or after further mixing, if necessary, in a mixing chamber (not shown separately) with other additives via a pre-granulate outlet 213 into the final granulator 211.

Abstract

L'invention concerne un granulat ainsi qu'un procédé et un dispositif pour la production de granulats. L'objectif de l'invention est de permettre l'obtention d'un granulat à base de matières premières renouvelables, qui puisse être utilisé comme matériau à mouler par injection et dont on puisse faire varier les caractéristiques mécaniques et d'autres caractéristiques physiques sur une large plage, par incorporation d'additifs. Le procédé selon l'invention offre l'avantage résidant dans le fait que la production du granulat peut se faire sans prétraitement particulier des éléments végétaux utilisés. Pour la mise en oeuvre du procédé, on utilise un dispositif qui peut être constitué d'un prégranulateur et d'un granulateur terminal, et éventuellement seulement d'un prégranulateur. On obtient un granulat particulièrement propre grâce aux différentes configurations du granulateur terminal, lequel peut être pourvu, par exemple, de matrices tournant l'une contre l'autre ou bien de matrices tournant l'une dans l'autre.
