Incredibly different COMPEO

COMPEO – Compounder for plastics and elastomers   2020-05-26T11:03:30+02:00       COMPEO

The new compounder generation.
Incredibly flexible.
The polymer industry’s innovation and earnings potential lies in the production of extremely  high quality  compounds.
End products should be rein forced , scratch-resistant, flame-retardant, weather-resistant and at the same time resource-saving.
This requires a compounder which easily and thoroughly mixes in  significant  amounts of additives.
Meet COMPEO, the new state-of-the-art compounder delivering more diversity in its  application , greater flexibility in process engineering, and increased value added in compound manufacturing.
COMPEO – in motion!.
„Incredibly flexible.“ This is  the promise  of our new COMPEO compounder generation for the polymer and plastics industry.
COMPEO is the new.

Ultra-modern compounder with twin screw extruder from BUSS

which offers more variety in application, more flexibility in process engineering and a higher added value in compound production.

COMPEO – the best from all series!

The allrounder among the compounding systems.

COMPEO combines its predecessors’ performance and robustness in a unique

multifunctional series.
The series was developed for all  temperature  ranges up to 400°C.
It has a process window that is unparalleled.
Given the system’s modular construction and novel process geometries.

COMPEO can be used within an extremely diverse application spectrum

extending far beyond previous Buss Co-Kneader applications – from temperature-sensitive thermosets to demanding, technical thermoplastics.
The newly developed machine concept.
Thanks to its modular structure, the COMPEO series can be precisely configured to meet the specific compounding  application .
Systematic  standardization  of the modules used results in considerable investment cost savings.
Maintenance outlay is kept low by using highly resistant surface-hardened materials in  the process  zone.
The ergonomics of the COMPEO system design simplifies operation and simultaneously reduces application errors and downtimes.
Improved raw materials feed.
The new COMPEO series achieves the performance of its predecessor series using lower speeds, but also due to ideal fill levels.
As a standard, raw materials are metered in freefall via an enlarged inlet opening.
Alternatively, inlet screws or side feeders can be used.
Thanks to the operating principle of the twin screw and backventing, they ensure efficient feeding, even if there are high filler contents.
Very operator-friendly and energy-efficient.
When designing COMPEO, emphasis was placed on ergonomics, ease of maintenance, and energy efficiency.
Pipes and lines are laid mostly inside the machine behind easy-to-clean panels.
The gearbox is covered with a soundproofing hood that also improves operational safety.
To minimize energy losses, the process section is thermally insulated.
One design – different sizes!.

COMPEO – new geometries for greater flexibility!
COMPEO’s innovative operating principle

In the basic version with two inlet zones, polymers, additives and some of the fillers are fed through the first intake opening.
The polymers are molten and mixed with the additives in the melting zone.
In the second feed zone, further fillers are added via a side feeder and distributed homogeneously in the downstream mixing zone.
Incredibly flexible.
Incredibly different.
Volatiles and entrapped air are removed in the degassing zone before transfer to the discharge unit.
The processing length, type and number of feeding units, temperature, degassing and process geometries are defined according to the compounding application.
New screw geometries extend the process window.

The new COMPEO series screw geometries ensure high throughputwith up to 20% lower RPM

Increasing the volume-related torque by 15% enables the configuration of longer mixing zones.
That results in more stable process conditions without a higher energy input. The systematic free-form surface design of the screw flights ensures evenly intense shearing of the product and eliminates local overheating.
The configurable process zone of the COMPEO compounder opens up completely new process engineering possibilities through the application of mixing and kneading elements with two to six rows of flights.
The combination of traditional three and four flight elements with newly developed mixing elements allow, for one thing, achieving goals which in the past conflicted with each other, such as high specific throughput with controllable energy input.
For another, .

The COMPEO process window is considerably larger than those of previous models

Throughput can be varied in a ratio of 1:6, increasing both system flexibility and user-friendliness.
The high throughput ratio is particularly advantageous for starting up, for small lots, and for in-line processes, where the downstream unit requires consistent product quality even with greatly varying throughput rates.

COMPEO – efficient down to the last detail!

Innovative discharge concept.
Pressure build-up at the end of the production process is at least just as important for perfect pellet quality as fully homogeneous mixing of the various raw materials in the compounding step.
The discharge unit is decisive for this.
It ensures optimum und reliable pressure build-up required for downstream units such as screen changers and pelletizers, independent of the compounder.
The innovative COMPEO also enables the realization of hybrid systems for processing widely differing products.
Efficiency, quality and user-friendliness.
The new COMPEO discharge unit, based on the principle of a conical twin screw, is designed to run in a metered method.
As a result, the entire pressure build-up takes place in the slowly rotating twin screw, thus reducing temperature increases at the transition from compounder to discharge unit.
The operating principle of the screw pump also guarantees maximum conveying efficiency in case of higher back pressure, enabling minimization of the speed and potential temperature increase.
The COMPEO discharge unit has a wide range of application possibilities and is exceedingly user-friendly.
The retractable housing gives full access to the conveying screws for cleaning and maintenance.
COMPEO – system control 4.0.
Intuitive operation of control panel, Industry 4.0 connectivity.
The touch-screen equipped control system is based on a state of-the-art controller (Siemens or Allen Bradley) and has an OPC-UA interface for connection to higherlevel IT architectures.
This interface makes the system fully Industry 4.0 compliant.
The modular software is structured according to the system configuration and can be operated intuitively.
The control system works with stored formulation parameter sets, which makes it possible to switch between formulations with the push of a button.
All essential system parameters such as fill levels, flow rates or quantities, pressures, temperatures, and outputs are visualized, recorded, and archived.
Defined process parameters such as temperatures, power consumption or specific energy input, and thus the efficiency of the system, are continuously monitored by the control system.
Optionally, the system can also be maintained via remote diagnosis and remote maintenance.
Unique features.
