Used Coperion Werner & Pfleiderer ZSK 58 Twin Screw Extrusion Line

Manufacturer Information

Coperion and Werner & Pfleiderer are established names in twin screw extrusion and polymer processing technology. The ZSK series is widely associated with co-rotating twin screw extruders used for compounding, mixing, and processing polymer materials. Integrated extrusion systems can combine controlled feeding, melting, mixing, side feeding, cooling, and pelletizing operations for industrial plastics processing.

Main Product Description

Used Coperion Werner & Pfleiderer ZSK 58 twin screw extrusion line previously used in a masterbatch application. The system includes a Brabender feeding and dosing arrangement with two pre-dosing units, two gravimetric dosing units, and one volumetric dosing unit, along with a Coperion Werner & Pfleiderer ZSK 58 twin screw extruder featuring two 58 mm diameter co-rotating, intermeshing screws and a 46:1 L/D ratio. The extruder is equipped with ten electrically heated, water-cooled barrel sections, a gearbox-driven screw system rated for a maximum speed of 1,200 RPM, and a die head. Additional equipment includes a frame-mounted Coperion ZS-B 58 twin screw side feeder, complete strand granulation system, cooling unit, and control panel with Siemens S7-300 controller. The line is supplied with pumps, sensors, associated infrastructure, one pair of spare screw shafts with screw set, and miscellaneous spare parts. Previously operated for masterbatch production, this extrusion line may also be suitable for compatible polymer compounding, color concentrate processing, plastics blending, and specialty compound pellet production.
