The ideal compounder for the highest quality demands.

Optimal process design through the optimal balance of screw volume, torque and speed.
Coperion Werner & Pfleiderer has raised the bar for productivity with the introduction of the ZSK MEGAcompounder. The ZSK MEGAvolume series is designed to complement the ZSK MEGAcompounder, and at the same time deliver the maximum amount of volume with the highest specific torque. The results: an even better cost / performance ratio, higher productivity and optimal design through the new, unusual dimensions.

Consequently, the ZSK MEGAvolume series is ideal for processes with a demand for specific energy < 0.1 kWh / kg and a simultaneous high volume demand, especially in the chemical, food and plastics industries.

The areas of application are:
-Processes with a high demand for volume, e.g., products with a low specific weight, difficult feeding behavior or products with high filler content
-Degassing processes, e.g., with substances containing solvents
-Processes with a high demand for heat exchange surfaces, e.g., with reaction processes
-Processes with low energy consumption

The processing steps in compounding are:
-Metering
-Feed intake and conveying
-Melting Dispersion / Homogenizing
-Degassing
-Pressurization
-Screening
-Shaping

New dimensions for more productivity.

Modular construction. Maximum speed. Highest free volume. Balanced design of the drive power. Maximum life cycle. Optimal size increases. reliable scale-up. flexible control system.

Coperion Werner & Pfleiderer is the technology leader in the area of twin-screw compounder systems. Many technical achievements and in-novations have been developed by Coperion – including the ZSK MEGAvolume. With special dimensions of screw volumes, screw speed and torque, this series offers many advantages in numerous applications.

ZSK 43 MEGAvolume in compact-version.

Screw volumes.
Due to the deeper cut screw channels with a Do / Di ratio of 1.8, the free volume is considerably higher.

The advantages are:
- Improved feed intake of materials with a low bulk densities, e.g., flours and starches
- Lower Shear Stresses
- Reduced thermal stress of the raw material
- Higher residual time for reaction processes

Screw speed.
The ZSK MEGAvolume-series is designed for speeds up to 1,800 rpm.

The advantages are:
- Economical cost / performance ratio
- Increase in performance with the samemachine size by 3-4 times
- Lower investment and operational costs with smaller machine sizes at the same throughput
- Increased throughput range

Torque.
The specific torque of the ZSK MEGA-volume (Md / a³ = 8.7 Nm /cm³), in comparison to the Continua (Md / a³ = 4.3 Nm / cm³), produces economic and technical process improvements for processes at torque limits.

The advantages are:
-Considerably higher throughputs
-Greater residence time and higher screw speed range with critical and sensitive products
