dosing blending

 Dosing & Blending

Traditional Options for Processors

the dosing choices
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
dosing by volume
Dosing by Volume
  • The Most Common Methods :
      • ‘Pocketed Wheel’ Metering
      • ‘Screw’ Metering
problems volumetric dosing
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
blending requirements
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
gravimetric blending

 Gravimetric Blending

Introduction to Maguire Technology

why gravimetric
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
  • 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 %

client cost analysis

 Client Cost Analysis

Increased performance at a lower cost

cost savings
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.

cost saving analysis
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

cost saving analysis63
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 saving

20% of US$320,000 masterbatch =

US$ 64,000 in masterbatch saved per annum

compound v natural
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
