2 Plants and Extrusion Systems

3 Coperion: Together - for Our Customers' Success
America Europe Asia 2,000 employees 20 subsidiaries worldwide EUR400m sales GEORG FISCHER +GF+ (50,1%) West Private Equity / WestLB (49,9%)

4 ZSK MEGAvolume Compounding with large screw channel volume
MEGAcompounder with high torque Introduced at K‘ 1995 MEGAvolume with large screw volume Introduced at K‘ 2001 represents a second ZSK series

5 ZSK MEGAvolume Compounding with large screw channel volume
MEGAvolume with large volume for products with low bulk density for processes with low specific energy input (< 0.1 kWh/kg)

6 Characteristic dimensions of co-rotating twin-screws
2-flighted profile Diameter ratio: OD / ID Specific torque: Md / a3 OD OD = Outer screw diameter ID = Inner screw diameter a = Center distance ID a Weller,

7 OD to ID Ratio

8 Development of the ZSK ZSK Standard OD / ID = 1.25 ZSK-Variable
Balanced ratio of free volume and torque ZSK Standard OD / ID = 1.25 ZSK-Variable OD / ID = 1.44 Free volume Torque ZSK Super Compounder ZSK MEGA Compounder OD / ID = 1.55 OD/ID Free volume and permissible torque as a function OD/ID CONTINUA OD / ID = 1.71 Weller,

9 ZSK Mv (MEGAvolume) Da / Di = 1,55 Da / Di = 1,80 Da / Di = 1,55
Flight Dep[th Free Volume and Allowable Torque shown as a function of Flight Depth Free Volume Balanced ratio of free volume and torque ZSK Standard Da / Di = 1,25 Increasing Torque and Volume Torque ZSK-variabel Da / Di = 1,44 Increasing Volume ZSK MEGAvolume Da / Di = 1,80 ZSK Super Compounder Da / Di = 1,55 Increasing Torque Same Center Distance ZSK MEGAcompounder Da / Di = 1,55 Same Center Distance

10 ZSK Mv (MEGAvolume) Result: Deeper Flights Allow Higher Screw Speed
Better Feed Lower Sheer Lower Material Temperature Lower work on the product - depending upon the process can produce better quality Reliable Devolitilization v u Sheer speed gamma = vu /h h max h' Da/Di = 1,8 Da/Di = 1,55 ZSK Mv Result: Deeper Flights Allow Higher Screw Speed

11 Effect of OD/ID & RPM on average shear rate

12 ZSK Mv (MEGAvolume) Higher Volumes through Expansion of the Barrel Bores and Deeper Cut Screw Flights MEGAcompounder Da / Di = 1,55 MEGAvolume Da / Di = 1,8 Di Da

13 ZSK Mv (MEGAvolume) Progression of Free Volume

14 ZSK Mv (MEGAvolume) Application Examples
Experiences with Process Technology and Production Processing of Highly Filled Compounds Increase of throughput up to 50% with the same RPM - Increase of filler (SiO2) from 15% to 20% Production of Powder Coatings % higher discharge efficiency - Possibility of feeding higher rates of fines Food Extrusion % more throughput in the production of pet foods
