WiPa develops with the recyclingsystem ZTE a pelletizing unit for most plastics. The most advanced pelletizing system!

The original waste material like film, fiber or blown materials is transported into the crushing unit on a conveyor belt or by means of draw-in rollers. The Reactorunit crushes and compacts the material, then presses it into the compensation screw. The high-power extrusion machine assures melting in a gently way. The melted material is filtered through the continuous operating screenchanger and cutted at the die-head. The granulates produced are cooled down by means of water, with separation taking place in a vibrating table. In the ensuing centrifuge all residual humidity is removed. Depending on the customer´s requirements, the granulates can then be stored in a siling facility, a container, or in bags. The optimum processing of waste material is achieved with minimum investment and production costs using these highly competitive machines.

Cutting Unit TA

The cutting unit consists of an open easily accessible drum with rotating cutting elements that cut, densify and impel the material into the intermediate screw. A range of cutting rotors is available for different applications. The cutting unit can be decoupled from the extruder, thus production changes can be easily done.

Compensation Screw

The special compensation screw acts as a stuffing device for the extruder. This system hedges against material fluctuations and provides a constant material flow. Another benefit is the pre degasing of the material by what the main degasing in the extruder is relieved.

High-Power extrusion machine PME

The densified material is passed through a extruder for further gentle plastification.

Precisely defined parameters guarantee dry and regular granulates. Regrind can be transported into the extrusion hopper immediately without passing the cutting unit and thus be directly converted into plastic material.

Screenchanger WS

Continously working screenchanger with cylindrical filters. The cylindrical filters give a very large screen area in a small machine what saves place. A further benefit is that the screen mesh is in a rectangular form, so it is easily prepared and avoids the off-cuts necessary for circular screens.
