7.  Dosing & Blending Traditional Options for Processors

8. The Dosing Choices • In general, a processor who is going to switch from pre compounded materials to raw materials will have 3 options for mixing. • Proportional Valve + Doser • Volumetric Blending • Gravimetric Blending

9. Dosing by Volume • The Most Common Methods : • ‘Pocketed Wheel’ Metering • ‘Screw’ Metering

15. Closed Loop Systems

16. Problems : Volumetric Dosing • Time consuming manual calibration • Skilled personnel required for setting • Formulas and process data required for calibration • Assumes consistent bulk density of materials

17. Blending Requirements • Minimise labour • Minimise involvement of skilled personnel • Accurately control material usage • Cut waste and scrap • Less down time; More production time • Repeatability of product • Peace of mind

18.  Gravimetric Blending Introduction to Maguire Technology

19. Why Gravimetric ? • Technological affordability • Consistent accuracy • Automatically adjusts for variations in bulk density • Calibration is an automatic function • Setup in minutes - not hours • Measures by Weight - not Volume • Eliminates errors calculation
