Structure and Components

Modular and individually adaptable

Optimise your production processes or accelerate the development of new products. ENTEX’s unique and pioneering modular system offers unprecedented economic and technical benefits. Its modular construction allows as many as 8 roller cylinders to be connected in series.

01 – Single screw feed cylinder

Feed cylinders serve as an interface between the solid material supply and the process section. The feed screw conveys the raw material into the process zone, which is where the actual compounding process begins.
Alternatively, it is also possible to use the feed cylinder for back venting.

02 – Planetary spindle feed cylinder

Planetary spindle feed cylinders can be used when it is necessary to draw materials with high adhesion properties or very low bulk densities into the process. The material is conveyed directly into the tempered compounding process between the rolling planetary spindles, where it is integrated very effectively.
These cylinders can be installed at any point on the process section.

03 – Injection ring / Spray ring

Injection and spray rings can be equipped with multiple injection bores for the installation of injection valves and/or injectors through which liquids can be injected into the process section.
Liquids can also be injected at other points on the process section.

04 – Roller cylinder (module)

Each roller cylinder represents a process zone that can be controlled through targeted thermal and mechanical regulation.

05 – Side feeder for solids supply

Formulation-specific amounts of solids can be fed into the ongoing process at different points using side feeders. This is advantageous for particularly sensitive materials and for reactive processes.

RETURN TO OVERVIEW

06 – Dispersion ring

Dispersion rings are used for axial fixation of the planetary spindles and for mechanically regulating the melt flow. The melt behaviour in each individual process zone of the process section can be influenced using interchangeable dispersion inserts with different inner diameters. Dispersion rings can also be used for liquid injection.

RETURN TO OVERVIEW

07 – Toothed intermediate ring

If large spatial volumes are required, such as for efficient degassing processes or feeding large volumes of solids with low bulk densities, several roller cylinders can be coupled with toothed intermediate rings to create a single large process zone.

RETURN TO OVERVIEW

08 – Pressure, temperature and colour measurement

Different sensors can be installed at numerous locations to optimise process monitoring. This makes it possible to monitor the melt pressure and melt temperature in every process zone. It is also possible to use colour measurement sensors to monitor product quality.

RETURN TO OVERVIEW

09 – Degassing (via side feeder)

It is also possible to use side feeder connections on roller cylinders for the evacuation of volatile substances such as vapours, gases or degradation products.

RETURN TO OVERVIEW

10 – Discharge elements

Depending on the process requirements, various front rings, discharge adapters and round dies with and without temperature control can be provided.
