RST introduces coal treatment system
RST’s Total Coal Control technology is designed for fine particles management during coal transportation. The company says the technology stops coal fly-aways, improves movability and offers a full quality control treatment during the material handling process.
RST technical and operations director, David Handel, said “Our aim was to develop a product that not only did its job in terms of dust suppression, better control and less escapement, but also treated the coal within containment to ensure the best possible product is delivered at the end of the line.
“[RST] estimated Queensland pumps out around two million rail wagons of coal a year with 80t of coal per wagon, however the quality of coal is often ruined during the material handling process.
“By using TCC we are able to stop degradation occurring, which in turn gives coal buyers a delivered product that has a higher calorific value than non-treated coal.
“This is very important as the calorific value measures the energy produced by the coal, a higher value will therefore maximize the coal’s worth. So an increase of 3% in value is worth a significant amount of money.”
Handel said TCC also had the ability to protect coal from moisture and oxidation, prevent self-combustion within stockpiles and control coal dust, rain erosion, slumping and material loss.
“Benefits to coal stockpiles also include improvements to the control of self-combustion, minimisation of water penetration, reduced hang up and carry back during conveying and transport, and the improvement of fines recovery at the coal washeries.”
