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.

Coperion twin screw extruder ZSK screw elements

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.

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 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

Electronically Secured Maintenance Opening at Gearbox Lantern

Coperion Extruders - Electronically Secured Maintenance Lock at Gearbox Lantern

The gearbox lantern of Coperion ZSK twin screw extruders can be optionally equipped with an electronically secured maintenance opening. As soon as the screw shafts come to a complete stop, service personnel can open the gearbox lantern without tools, guaranteeing secure, easier access to the screw shaft coupling.

This feature, which is available from a size of ZSK 32, significantly simplifies screw changes and maintenance, which again reduces the machine’s downtimes, thus contributing to greater efficiency of the system.
