Our counter rotating conical twin screw have following features :
- Conical twin screw machined on CNC"WMW" Germany make thread milling machines by simulation software for better performance.
- Conical twin screw and barrel are specially designed for high calcium loading.
- compact&reliable gearbox
- designed for high output at low screw speed and less power consumption.
- Two piece barrel construction for economical replacement can be provided.
- Bi-metallic screw&barrel can be provided for two-three times more lifespan than nitrided
