Dosing & Blending
Traditional Options for Processors
![Page 8: Maguire Gravimetric Blending. Introduction Products & Software](https://reader030.vdocument.in/reader030/viewer/2022032802/56649e005503460f94aea257/html5/thumbnails/8.jpg)
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
![Page 9: Maguire Gravimetric Blending. Introduction Products & Software](https://reader030.vdocument.in/reader030/viewer/2022032802/56649e005503460f94aea257/html5/thumbnails/9.jpg)
Dosing by Volume
• The Most Common Methods :
• ‘Pocketed Wheel’ Metering• ‘Screw’ Metering
![Page 10: Maguire Gravimetric Blending. Introduction Products & Software](https://reader030.vdocument.in/reader030/viewer/2022032802/56649e005503460f94aea257/html5/thumbnails/10.jpg)

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
![Page 17: Maguire Gravimetric Blending. Introduction Products & Software](https://reader030.vdocument.in/reader030/viewer/2022032802/56649e005503460f94aea257/html5/thumbnails/17.jpg)
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
![Page 18: Maguire Gravimetric Blending. Introduction Products & Software](https://reader030.vdocument.in/reader030/viewer/2022032802/56649e005503460f94aea257/html5/thumbnails/18.jpg)
Gravimetric Blending
Introduction to Maguire Technology
![Page 19: Maguire Gravimetric Blending. Introduction Products & Software](https://reader030.vdocument.in/reader030/viewer/2022032802/56649e005503460f94aea257/html5/thumbnails/19.jpg)
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

Accuracy
• Every batch followed by error correction routine
• Accuracy rises by restricting a slide gate or auger feeder
• Immune to vibration
1% Setting = Typical accuracy of + / - 0.05 %

Cost Savings
• Why specify a Maguire?
Maguire now is proven as the market leader due to features and benefits at an affordable price.
• How can Maguire help with Materials?Maguire gives the manufacturer the ability to blend with ease and confidence at a fraction of the cost of utilising a compounded material.
![Page 62: Maguire Gravimetric Blending. Introduction Products & Software](https://reader030.vdocument.in/reader030/viewer/2022032802/56649e005503460f94aea257/html5/thumbnails/62.jpg)
Cost Saving Analysis• Time
5 days, 20 hr/day, x 50 weeks = 5000 hr/yr• Materials
200 kg/hr = 1,000,000 kg consumption• Masterbatch addition
2.0 % masterbatch used = 20,000 Kg/yr• Price
masterbatch price US$16/Kg = US$320,000 per year
![Page 63: Maguire Gravimetric Blending. Introduction Products & Software](https://reader030.vdocument.in/reader030/viewer/2022032802/56649e005503460f94aea257/html5/thumbnails/63.jpg)
Cost Saving Analysis
• Maguire In our experience with volumetric systems we estimate that processors while aiming to dose at 2.0% actually dose between 1.9% to 2.6%; on this basis 20% fluctuation is not unusual
• Financial saving20% of US$320,000 masterbatch =US$ 64,000 in masterbatch saved per annum
![Page 64: Maguire Gravimetric Blending. Introduction Products & Software](https://reader030.vdocument.in/reader030/viewer/2022032802/56649e005503460f94aea257/html5/thumbnails/64.jpg)
Compound v Natural
• The savings for companies using compounds will again be high.
• Direct material costs savings can range from 5% to 30%.
• Indirect costs for the manufacturer include– Warehouse & Stocking– Distribution costs– Re Drying– Materials degradation in regrind
