1. PURPOSE AND MAIN FUNCTIONS OF THE LINE

The extrusion line for powder coating production is part of a whole production process and is used for the production of polymer powder coatings. The extrusion line includes the following technological processes: formation of a homogeneous melt of heated powder coating by mixing, shaping of the melt, subsequent cooling of the product and its crushing into fine fractions.

2. LINE COMPONENTS

- Twin-screw extruder type XTS

3. DESCRIPTION OF THE EXTRUDER COMPONENTS

3.1. Twin-screw extruder type XTS 35

The extruder for powder coating production consists of:
- 24D hydraulically opening barrels at the top and bottom, providing quick access for cleaning, maintenance and emergency repair of barrel liners and screw element shafts.
- Rectangular loading port for dosing of materials which are difficult to dose.
- Robust high flow water cooled units with 5 electrically heated (aluminium bronze heating plates of 2 kW each) control zones that provide excellent temperature control. Maximum operating temperature is 350°C.
- The barrel on the discharge side is equipped with a cooled discharge adapter and a knife.
- Screws with screw elements. Screw speed 0 - 900 rpm. Water cooled AC motor power of 26kW. The stepless (PIV) gearbox is rated at 139Nm and protected by an automatic torque limiter.
- Latch lock / quick-release coupling of shaft connection and toothed shaft.
