Method and apparatus for mixing and continuous extrusion of polymer materials with dry pre-mixing of the material

摘要

Method for mixing polymers and fillers by means of a continuous machine (1) of the horizontal type with two parallel shafts (5,6), which comprises the following stages: supplying of the raw material to the said machine; feeding of the raw materials to a pre-mixing zone; dry pre-mixing of the raw materials; feeding of the mixture to a first mixing zone; mixing of the mixture; feeding of the homogenized mixture to the outlet of the machine and associated machine for implementing the method. <IMAGE>
