Projects
Minprovise – Eastern Australia was awarded a contract in May 2011 to realign and re-profile a stockpile reclaim conveyor at a major east coast coal terminal. The conveyor in question, with two convex and two concave curves, has been problematic with belt tracking issues and regular spillage from the belt. The conveyor, located in a reclaim tunnel, is roof suspended with 3 stockpile reclaim feeders.
Prior to engaging Minprovise, the conveyor could only run at approximately 2500tph before product would spill from the conveyor resulting in excessive downtime for cleanup. The original conveyor design was for 4500tph.
After negotiation, Gary Everson (Manager – Eastern Australia) was awarded the project to re-align and re-profile the conveyor by modifying the concave and convex curves that a previous contractor had recommended.
A Minprovise team was mobilised and the work was successfully completed in 8 days with 2 shifts working around the clock. All conveyor sections were straightened and levelled and rollers aligned. One convex curve was removed and the remaining 3 curve radii modified to improve belt carrying capacity, steerage and correct entry to the loading section of the conveyor. Head and tail pulleys were also realigned and weigh stations set up correctly for calibration. Conveyor loading zones and chute skirts were also realigned to ensure optimum belt entry and material loading.
Commissioning was completed on the 26th May and a peak throughput of 5600tph was achieved without spillage. This represents a significant operational improvement and results in the conveyor being able to run at its designed throughput of 4500tph continuously with one or a combination of stockpile feeders in operation. The end result is faster ship loading times and no need for cleanup crews.
