bulk densities (venting is achieved by the axially displaced arrangement of the openings). The Argus installation also uses a
Leistritz side degassing system. The large free volume in the screw flight of the extruder in combination with the continu- ous renewal of the product surface are said to create optimum conditions for degassing of the polymer melt. The two co-rotating screws in the degassing unit push any escaping melt back into the process chamber while allowing gases to escape
while preventing blockages or deposits in the degassing barrel.

Flexible options Italy-based Maris developed the TM20 Hi-Tech co-rotating twin-screw extruder for laboratory and small-batch compounding applications, including production of general compounds, techno-poly- mers, polymeric alloys, reactive extrusion, and
colour and additive masterbatches. The company says the extruder has the flexibility to allow fast configuration changes depending on the raw materials used and the type of process. This can be done easily due to the use of interchangeable and modular mechanical components that allows reconfiguration without the intervention of special- ist technicians. The machine is also said to be quiet and suitable for environments such as educational and research organisations. The TM20 Hi-Tech gearbox is lubricated in an oil
bath. Barrel cooling is provided by a closed loop water circuit that cools each part separately. Barrel and screw elements can be constructed from a wide selection of nitrited, anti-corrosive and anti-wear steels. The screw geometry is self-clean- ing and of the two-lobe design. Locating the electrical cabinet inside the
supporting frame means the TM20 Hi-Tech extrud- er is highly compact. The operator panel is mount- ed on a movable arm fixed to the top of the equipment main frame, which makes it easy to access the extruder control parameters. The TM20 Hi-Tech uses a control system based on a Siemens PLC series S7 and a graphic touch control panel.
