Claims20
An equipment for producing polymer pellets comprising one or more polymer components and one or more further components, which equipment comprises at least one first mixing apparatus for introducing at least one of said further component(s) onto polymer pellets, which said first mixing apparatus comprises:
- an inlet for feeding polymer pellets into said first mixing apparatus,
- a first mixing section provided with mixing means for moving and mixing said pellet stream along said section,
- at least one means for applying said at least one further component(s) onto the fed polymer pellets at one or more positions selected from prior to said apparatus, at said inlet of said apparatus, and/or within said section of said apparatus, and
- an outlet for removing the mixed pellet stream from said first mixing section,
- wherein said means for moving and mixing said pellet stream in said section is selected from the group consisting of one or more of a vibration means, oscillation means and fluidisation means.
