>> With extraordinary parameters for screw volume, screw speed and torque, this series offers numerous advantages for a huge number of applications.

ZSK MEGAvolume PLUS

Coperion sets new standards with the ZSK MEGAvolume PLUS: The extruder series unites an optimally balanced large free screw volume with high screw speeds and a high specific torque. Products with a specific energy requirement < 0.13 kWh/kg can be produced with much higher throughput rates as a result. The formulation flexibility and the productivity of the plant increase considerably.

Typical areas of application of the ZSK MEGAvolume PLUS

Processes with a high volume requirement such as products with a low bulk weight, poor feed properties or high filler content

Degassing processes, e.g. for substances containing solvents

Processes with a high requirement for heat exchange areas, e.g. in reaction processes

Processes with a low energy requirement

Shear-sensitive products (PVC, HFFR, pearl gloss pigments)

PP / hollow glass

Rubber

Polymerization (PU, POM)

Powder paint

Petfood

Cereals, starch

Catalyst compounds

Adhesives

Sealing compounds

Special features of the ZSK MEGAvolume PLUS

Screw volume
The free screw volume is very high due to the deeply cut screw channels with a diameter ratio D_o/D_i of 1.8.

The advantages
Improved feeding of additives with a low bulk weight such as flours, starches, pigments, fillers, additives
Lower shear stress
Reduced thermal stress of the raw materials
Greater residence time for reaction processes
Safe degassing

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

The advantages
Increase in the throughput rate by 3 or 4 times in comparison with the predecessor model ZSK MEGAvolume
Good price/performance ratio
Lower investment and operating costs due to smaller machine sizes for the given throughput rate

Torque
The specific torque of the ZSK MEGAvolume PLUS is 11.3 Nm / cm³. It has been increased by 30 % in comparison with the predecessor model ZSK MEGAvolume.

The advantages
A further increase in the throughput rate of up to 40 % in comparison with the predecessor series
Extended operating window
Greater formulation flexibility

From size ZSK 34 to ZSK 76 the ZSK MEGAvolume PLUS series is available in the compact version with integrated control system. This ensures fast, easy installation and start-up.
