GEN 7 . LONG-LIFE ROLLER2018-12-13T08:09:39+00:00

Project Description

LEADING THE WAY

Reduction of Unscheduled down time: Robust by design to reduce failure rate at site.

Engineered for reliability, greater load-bearing capacity, and a longer life span than conventional rollers.  Gen 7 is lighter for the longer length roller … where it counts!

Savings on Roller Replacement

Graph I. This mine has 21,000 rollers on site.  CII supplied large numbers of rollers – the requirement for rollers peaked in July 2018, and has steadily reduced since using CII Rollers.  The savings became even more significant over time.

Savings on Labour & Replacement

In our experience, CII rollers should last for about 3 times that of a conventional roller.

  • If a mine were to change out 2,000 rollers per annum this would equate to about $346,000 plus the cost of the rollers.
  • Case I: At one port where 30 CII Gen 5, idler carbon steel rollers were installed on 17 October 2012, all of these are still running.
  • As at 26 October 2017 the engineer reported 77,550,306 tonnes of coal from 11,533 trains has passed over those rollers:
  • Case II: A return roller on a ramp conveyor at a mine site, situated just after end pulley – 120 metres from the ground, generally had to be replaced about every 8-10 days.  This would result in significant unscheduled down-time.
  • Solution: One CII VitreSteel roller was used as a replacement roller.  It was found to be still working after 2 years with significant savings, increased productivity, labour and replacement rollers costs.  The weakest link in the chain had been replaced.  The savings amounted to millions of dollars.

Graph 2019: For the first 5 months the replacement rollers show a continuing downward trend for 4 years.  The replacements illustrate the declining purchase of conventional rollers, due to replacement by CII (which have not required replacement to date).  The savings are significant.
