ZSK Mv PLUS Extruder

The ideal extruder for products with high volume requirements

Coperion sets standards with the ZSK Mv PLUS twin screw extruder. This 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.

  • Devolatilization processes, e.g. in substances containing solvents
  • Processes with low energy consumption
  • Shear sensitive products
  • Carbon black masterbatch
  • PET masterbatch
  • HFFR (ATH, Mg(OH)2)
  • PVC
  • Effect-pigment masterbatch
  • Rubber
  • Polymerization (PU, POM)Powder Coating
  • Catalyst carrier
  • Adhesives, sealants
  • PP/hollow glass
  • Food
  • Pet food
  • Cereals, starch

Technical Advantages

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

  • 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

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

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

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

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