Advantages of the planetary roller system

1. repeated thin-layer rolling-out
2. most precise temperature control of all compounding systems
3. gentle material compounding
4. large processing bandwidth of most different materials
5. quick and trouble-free change of material
6. best self-cleaning effect, thus smallest waste quantities

7. modular construction
8. realization of delicate porocesses
9. ecological production with nearly no risk
10. cost-saving and high-quality production
11. sanitarily closed system
