CO-ROTATING TWIN-SCREW EXTRUDERS VM SERIES

Maris co-rotating twin-screw extruders of VM series have been designed to increase the performances, for those processes which require, particularly, big quantities of soft fillers, mainly having low bulk density or long residential time (reactive processes) or efficacy removal of volatile components (solvents and monomers) present even in high percentages.
Characterized by a ratio D/d of 1,78 and a maximum screws rotation speed of 1800 rpm, the specific torque value applied with respect to the cubed screws inter-axle, and the consequent advantages are:
- Higher output
- Costs and investments reduction
