Abstract
Method for continuously mixing polymer materials by means of a continuous mixing machine having a mixing chamber provided with at least one opening for supplying the polymer and at least one mouth for discharging the mixture and having arranged inside it a pair of rotors parallel with one another, the method includes the stages of: supplying the material and any additives to the mixing chamber through the supply mouth; and mixing and feeding the materials towards the outlet, by pre-mixing performed by axial sections of rotors rotating tangentially with respect to one another, and subsequent mixing performed by axial sections of the rotors rotating in a mutually intermeshing manner.
