The components of an extrusion line have to interact in an optimum way in order to reliably fulfil their process tasks. Leistritz builds the peripheral equipment that is placed directly at the processing unit in-house (e.g., side feeder, side degassing, vent, etc.). All other up- and downstream components are provided by our long-term partners. Our customers benefit from this proven cooperation, because it guarantees a smooth operation of the plant. In the early engineering phase we already compile all relevant parts for the process and specify important parameters: Which pneumatic conveyor? What kind of feeding system? Vaccum pump? Which pelletizer?
The LVE is a safe and simple alternative to conventional vacuum domes. The two screws, which rotate in the same direction are built into the degassing unit, push the possibly rising melt back into the process chamber, but allow all gases to escape. This prevents blockages or deposits in the degassing barrel. The large free volume in the screw channel (OD/ID = 2) creates optimum conditions for degassing the polymer melt.
This is what the LVE offers:
Old vacuum domes can easily be replaced by an LVE using an adapter.
