1 ZSK Mv (MEGAvolume)

2 Plants and Extrusion Systems

3 Coperion: Together - for Our Customers' Success America EuropeAsia 2,000 employees 20 subsidiaries worldwideEUR400m 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 Weller, Diameter ratio: OD / ID Specific torque: M d / a 3 OD = Outer screw diameter ID = Inner screw diameter a = Center distance 2-flighted profile OD ID a Characteristic dimensions of co-rotating twin-screws

7 OD to ID Ratio

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

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

12 ZSK Mv (MEGAvolume) Higher Volumes through Expansion of the Barrel Bores and Deeper Cut Screw Flights MEGAcompounder D a / D i = 1,55 MEGAvolume D a / D i = 1,8 DiDi DaDa

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 (SiO 2 ) from 15% to 20% Production of Powder Coatings - 60% higher discharge efficiency - Possibility of feeding higher rates of fines Food Extrusion - 60% more throughput in the production of pet foods
