EXTRUTEX ECK-70 Co-Kneader Extruder
Description
EXTRUTEX ECK-70 Co-Kneader Extruder
EXTRUTEX ECK-70 Co-Kneader Extruder – Professional Low-Shear Compounding System
The EXTRUTEX ECK-70 Co-Kneader Extruder is a professional continuous compounding system designed for medium-capacity polymer processing applications requiring excellent mixing, controlled temperature, low shear and highly consistent material quality.
With a 70 mm screw diameter, 55 kW drive power, maximum screw speed of 500 rpm and an output capacity of approximately 150–250 kg/h, the ECK-70 provides a powerful and flexible solution for industrial masterbatch production, specialty polymer compounds, engineering plastics, high-filler formulations and other demanding compounding applications.
The ECK-70 is based on the proven Co-Kneader principle, combining continuous screw rotation with reciprocating axial screw movement. This movement works together with stationary kneading pins installed inside the barrel to generate intensive but controlled mixing.
Compared with conventional extrusion systems that rely primarily on high mechanical shear, the ECK-70 provides efficient material homogenization while helping control melt temperature and unnecessary mechanical stress.
ECK-70 Technical Specifications
| Parameter | ECK-70 |
|---|---|
| Model | ECK-70 |
| Screw Diameter | 70 mm |
| L/D Ratio | 10–25 |
| Reciprocating Stroke | 10.5 mm |
| Drive Power | 55 kW |
| Maximum Screw Speed | 500 rpm |
| Output Capacity | 150–250 kg/h |
The ECK-70 can be configured according to the polymer type, formulation, filler concentration, additive system, required production capacity and downstream pelletizing equipment.
Advanced Co-Kneader Technology
The ECK-70 uses a different approach to polymer compounding compared with conventional single-screw extrusion and conventional co-rotating twin-screw systems.
The screw does not simply rotate continuously in one position. In addition to its rotational movement, the screw also performs a reciprocating axial movement.
This additional movement creates repeated interaction between the screw kneading flights and the stationary kneading pins inside the processing chamber.
As the material passes through the ECK-70, it is continuously:
- Divided
- Folded
- Stretched
- Recombined
- Redistributed
- Homogenized
This creates highly effective mixing throughout the processing chamber while maintaining controlled mechanical and thermal conditions.
Rotating and Reciprocating Screw
The specially designed screw is the heart of the ECK-70.
During operation, the screw performs two movements simultaneously.
The first is rotational movement, which provides material transport and continuous kneading.
The second is reciprocating axial movement, which moves the screw forwards and backwards through the kneading chamber.
The reciprocating movement changes the relative position of the screw flights and stationary pins, creating additional material displacement and transverse mixing.
This allows the ECK-70 to achieve effective homogenization without depending exclusively on extremely high shear.
The result is a controlled compounding process suitable for many polymers and formulations where temperature and material quality must be carefully managed.
A Different Approach to Polymer Compounding
The ECK-45 is based on a different compounding philosophy from traditional extrusion technology.
A conventional extruder primarily transports material forward through a rotating screw. The ECK Co-Kneader introduces another dimension to the process: the screw also moves backwards and forwards along its axis.
Special kneading flights on the screw interact with stationary kneading pins installed inside the barrel. During operation, the moving screw flights repeatedly pass the fixed pins, creating a controlled combination of longitudinal and transverse material movement.
The material is continuously:
- Divided
- Folded
- Stretched
- Redistributed
- Recombined
- Homogenized
This creates highly efficient mixing without requiring extremely aggressive mechanical shear.
Rotating and Reciprocating Screw Technology
The heart of the ECK-45 is its specially engineered reciprocating screw.
During operation, the screw performs two simultaneous movements:
Rotational movement provides continuous material transport and kneading.
Reciprocating movement changes the position of the kneading flights relative to the stationary pins and creates additional transverse movement of the polymer.
This combination significantly improves the mixing action inside the processing chamber.
Instead of allowing material to travel through a simple forward-flow path, the ECK-45 continuously renews the material around the kneading elements.
This helps produce a highly uniform compound while maintaining controlled processing conditions.
Low-Shear Polymer Processing
One of the major advantages of the ECK-70 is its ability to achieve efficient mixing with relatively low shear.
This is especially important when processing materials that are sensitive to excessive mechanical energy or high melt temperatures.
Some polymers, pigments, additives and specialty formulations can experience degradation when exposed to excessive heat and mechanical stress.
The ECK-70 is designed to provide effective kneading while minimizing unnecessary processing intensity.
Potential benefits include:
- Controlled melt temperature
- Reduced thermal degradation
- Improved viscosity retention
- Better color stability
- Improved additive performance
- Consistent compound quality
- More stable production conditions
The 70 mm processing diameter also provides substantially higher throughput than compact ECK models while maintaining the same basic Co-Kneader processing principle.
Excellent Dispersive and Distributive Mixing
The ECK-70 combines effective dispersive mixing and distributive mixing.
Dispersive mixing helps break down agglomerations of pigments, fillers and additives.
Distributive mixing ensures that these components are distributed consistently throughout the polymer matrix.
This combination is particularly valuable in masterbatch production and high-performance polymer compounds where even distribution of a relatively small amount of additive can have a significant effect on the final product.
The ECK-70 can therefore provide highly homogeneous compounds with:
- Uniform color
- Consistent filler concentration
- Stable additive distribution
- Consistent viscosity
- Improved material quality
- Repeatable production results
High Degree of Self-Wiping
The reciprocating movement of the screw contributes to a high degree of self-wiping inside the processing chamber.
The continuous interaction between the screw flights and stationary kneading pins helps minimize stagnant material zones and unwanted accumulation.
This is particularly useful when processing different formulations or colors on the same machine.
A cleaner processing chamber can help with:
- Faster product changeover
- Reduced contamination
- Easier cleaning
- More stable processing
- Reduced material residence
- Easier maintenance
For masterbatch manufacturers producing multiple colors and formulations, this feature can be especially valuable.
High Filler Loading Capability
The ECK-70 is suitable for formulations containing significant quantities of mineral and functional fillers.
Depending on the polymer and formulation, potential fillers include:
- Calcium carbonate
- Talc
- Barium sulfate
- Silica
- Mica
- Aluminum hydroxide
- Magnesium hydroxide
- Carbon black
- Wood flour
- Other mineral and functional fillers
The Co-Kneader processing mechanism provides effective filler incorporation while maintaining controlled processing conditions.
The larger 70 mm screw diameter and 150–250 kg/h output range make the ECK-70 suitable for industrial production where higher throughput is required.
Efficient Liquid Component Incorporation
The ECK-70 can also be configured for formulations containing liquid additives.
Examples include:
- Plasticizers
- Processing oils
- Waxes
- Liquid coupling agents
- Processing aids
- Liquid stabilizers
- Specialty additives
The continuous folding and redistribution of material inside the kneading chamber helps incorporate liquid components into the polymer matrix.
This makes the ECK-70 a flexible platform for formulations that combine polymers, powders, fillers and liquid additives.
