US-based Lawrence Nordell, president of Conveyor Dynamics, Inc (CDI), will deliver a technical session for the Australian Society for Bulk Solids Handling in Perth on Wednesday March 20th.
The 20km Westfarmers Curragh North conveyor designed by Laurence Nordell in partnership with construction firm Laing O’Rourke.
The session is entitled Recent Innovations in Design of Overland Belt Conveyors.
It draws on Nordell’s 47 years of conveyor design experience and an illustrious record in bulk solids research and consulting.
Since 1987, Nordell has worked closely with several Australian engineering and consulting houses on major overland conveyors.
His partnerships with firms like Laing O’Rourke have delivered advancements on many conveyors, including the 20km Rio Tinto Channar (1989), 5km Shell German Creek (1995), 7km BHP Bi-way (1997), 14km Westfarmers Muja/Collie (1997), 5km BHP Yandi (2004) and 20km Westfarmers Curragh North (2007).
In the technical session, Nordell will outline CDI’s approach to overland conveyor design, in particular its philosophy of “optimized total life cycle cost of ownership.”
The session will cover:
• Belt cost drivers: what is a good belt safety factor, cover gauge and specifications for wear and power; construction techniques that can save on raw material costs not practiced by belt suppliers/engineers.
• Belt construction limitations: idler junction pressure index (IJPI), belt squirm at high pressure point under steel cord and its consequences.
• Belt specifications: speed, cord construction, cord pitch, splice advancements, belt reels and limits of length/reel.
• Belt influence on power demand: rubber rheology’s importance and lack of engineers/users embracing the performance gains; historical measurements and 2+ year Newcastle University testing of idlers and power loss in belt-to-idler contact zone.
• Belt splice techniques: definition of belt safety factor (SF), splice pattern advancements and consequences, modern strength limits as dictated by the splice dynamic efficiency; even or odd belt steel cord count. Old and newer practices.
• Belt life expectancy: based on Discrete Element Method (DEM) modeling and historical data. How long should an overland belt cover and splice last? An opinion of good and bad practices.
The session runs from 11.30am to 2.15pm and includes a light lunch. It will be held at the Auditorium Engineers Australia, 712 Murray Street, West Perth.
The cost is a more than reasonable $15 for Engineers Australia and ASBSH members and $35 for non members.
