1 Total Cost of Ownership and Efficiency Aspects of Fluidizing Fabrics by Petra Muhlen Muhlen Sohn Ind., LP, USA for FICEM-APCAC, XXVIII, Congreso Técnico, Sao Paulo, Brazil August 18th 2011 Mühlen Sohn Slide 1

2 What is TCO? August 18th 2011 Mühlen Sohn Slide 2

3 Examples It is about: Short sections Lifetime of 24 month and less Narrow width Purchase price for fluidizing fabric typically between $300 and $800 Assumption: Price of high quality brand FLUITEX is 40% higher compared to standard fluidizing fabrics August 18th 2011 Mühlen Sohn Slide 3

4 Cement from Elevator to Pump $ Break-Even after 23 month Working conditions: Airslide: 26 meters Easily accesible Working temperature 100 C Installation appr. 15h w. 5 workers Calc. Downtime for the cement mill: 5000 $/h Month Basic invest: standard fluidizing fabric: $320 Replacement: every 12 month Installation: $375 Fluitex brand : $450 every 16 month $375 August 18th 2011 Mühlen Sohn Slide 4

5 Raw Meal to Bucket Elevator Working conditions: $ Break-Even after 4 ½ month Airslide: 6 meters Easily accesible Working temperature 120 C Installation appr. 6h w. 5 workers Calc. Downtime for the cement mill: 7000 $/h Month Basic invest: standard fluidizing fabric: $70 Replacement: every 8 month Installation: $150 Fluitex brand : $100 every 12 month $150 August 18th 2011 Mühlen Sohn Slide 5

6 Cement Mill to Bucket Elevator Working conditions: $ Break-Even after 3 month Airslide: 3 meters Easily accesible Working temperature C Installation appr. 6h w. 5 workers Calc. Downtime for the cement mill: 6250 $/h Month Basic invest: standard fluidizing fabric: $30 Replacement: every 12 month Installation: $150 Fluitex brand : $50 every 24 month $150 August 18th 2011 Mühlen Sohn Slide 6

7 Summary Part I It is about: Ratio between purchase price vs. installation cost Lifetime of the fabric Reduced downtime August 18th 2011 Mühlen Sohn Slide 7

8 What makes the difference? Part I The Raw Material Highest abrasion resistance through a smooth surface that is less sensitive to wear gives you the longest lifetime August 18th 2011 Mühlen Sohn Slide 8

9 Raw Material FLUITEX multifilament yarn standard spun yarn August 18th 2011 Mühlen Sohn Slide 9

10 Abrasion test today Summary: Abrasion figures are means of measuring the durability of a fabric and they allow comparisons of the relative life expectancy of various products. According to the test resulte and the feedback from our world-wide customers you are able to achieve up to 3 times longer lifetime by using Fluitex airslide fabrics. type of tester: Taber Abrader number of scourings: 1000 load: 500 g Speed: 60 scourings/min date of tests: January 2009 Abrasion Test - absolute values 0,3500 0,3000 0,2800 Gramm 0,2500 0,2000 0,1500 0,1000 0,0500 0,1300 0,0000 Fluitex E 800/5 spun yarn fabric Abrasion Test - relative values 1,20 1,00 0,95 values in % 0,80 0,60 0,40 0,48 0,20 0,00 Fluitex E 800/5 spun y arn f abric August 18th 2011 Mühlen Sohn Slide 10

11 Examples Silo Applications It is about: Permanent availability High risk in case of failures in the discharge system (uneven discharge can result in damages in the silo walls) High cost associated in case the silo would not empty If applicable, government regulations for recurring inspections August 18th 2011 Mühlen Sohn Slide 11

12 Minimize risk through the right fabric Having problems with your airslide dust collector? Do you see complete discharge of your silo? Do you have the feeling, that your airslide is working inefficiently? August 18th 2011 Mühlen Sohn Slide 12

13 What makes the difference? The Production Equipment Even aeration and flow of cement is a result of the same amount of air over the whole surface area achieved by low and uniform pressure drop in the fabric and gives you the most efficient material flow August 18th 2011 Mühlen Sohn Slide 13

14 Production Equipment Precision through laser cutting technology In-house engineered weaving machines August 18th 2011 Mühlen Sohn Slide 14

15 Examples Fluitex AD It is about: Temperature resistance Cut resistance FLUITEX AD fabric, the Kevlar version in our product range: Heat resistant up to 250 C Very cut resistant Assumption: Price of high quality brand FLUITEX AD is 6 times higher compared to FLUITEX polyester fabrics (heat resistant up to 150 C) August 18th 2011 Mühlen Sohn Slide 15

16 Mill discharge airslide Working conditions: Break-Even after 48 month Month 10 meters, 700 mm wide Temperatures from 80 to 180 C (depending on clinker temperature) Cyclical refit every 3 years (latest) Magnetic separator needs to be dismantled first 10h, 6 people involved Basic invest: FLUITEX E: 300 Replacement: every 18 month Installation: 1800 FLUITEX AD: 1500 every 36 month (fix!) 1800 August 18th 2011 Mühlen Sohn Slide 16
