PRF - Twin Screw Extruder

Twin-screw extrusion is used extensively for mixing, compounding, or reacting of polymeric materials. At PRF we have a high-speed co-rotating twin-screw extruder. The processing section of the unit is made up of several modular barrel sections which house the two co-rotating screw shafts. The barrel sections and screw elements can be freely combined so as to get an optimal arrangement matched specific processing needs.

Features and Benefits:

Extruder Specifications: Thorough Put: 40 Kg/hr, Screw Diameter: 30 mm, Length/Diameter Ratio: 16, Main Motor: 7.5 kW, Screw Speed: 0 - 600 rpm, Feeder Motor: 0.12 kW, Heating Power: 3.2kW.

Conveying Elements - The high-speed twin screw shaft is composed of shaft with spline or key, screw bushings for conveying and extrusion and kneading blocks for dispersion and homogenizing. The configuration of screw bushing and kneading block is changeable. High volume feed elements for the screw shafts provide improved material intake for materials with poor feeding characteristics.

Kneading blocks and Dispersive Mixing Elements - The mixing and kneading elements are designed in a variety of lengths, pitches and pitch direction. The result is precise shear, melt and energy control plus homogeneous mixing of the melt and dispersion additives. The machine can be fed with powder, pellets, chips, glass fiber, pastes and liquids.

Electronic Control Box - The high performance electronic control box in this unit has the advantages of high  reliability, good comprehension, compact structure, and can lock the major technology parameters with cipher code.

Extruder Barrel with heating/cooling units - There are a total of three heating/cooling zones in the extruder barrel.
