This plant is designed to provide a complete system for feeding the turbo mixer as well as the extrusion line, for the production of PVC film. The solution consists of storage silos for raw materials from which the PVC and Calcium Carbonate are extracted by means of pneumatic conveyor under suction for transfer to the cyclone filters for dynamic weighing of products. Big Bags emptying stations are present for Titanium dioxide and specific additives which feed the turbo mixer by means of a similar pneumatic system. The micro additives are added by means of special gravimetric dosing units, while the stabilising oils and plasticisers are taken from drums, dosed and injected into the mixer during the process by means of the special oils dosing station. When the mixing phase ends, the mixture obtained is again taken by suction and sent to a dosing unit which feeds the extruder by means of a continuous process.
