NATURAL GAMMA 1500
This analyser is an economical on-line ore quality monitoring system which is easily installed directly under production conveyor belts. The system does not contain any nucleonic sources and therefore does not require site to obtain a radiation license for its use.
The analyser uses the natural radiation signature of the material and known correlations with the composition to derive ore quality information.
The major features of the Natural Gamma 1500 include:
- Easy installation and simple operation
- No radiation sources – no requirement for licensing
- Underbelt configuration – suitable for coarse ore and high tonnage applications
- Fully automatic operation – no operator intervention required
- No mechanical moving parts – low maintenance costs
- Automatic electronic stability checks – drift free performance
- No operational upper limit to particle size or conveyed bed depth
- Flexible system interface to suit specific site requirements
- Non contact technique – no high wear components
- Superior total cost of ownership
- Designed for long product lifecycle
"When commodity prices were strong and rising, mining companies could afford minor inefficiencies in their plants. That is rarely the case in these days of lower-grade deposits, lower metal prices and economic pressure from every direction. “We have to do better with lower costs,” said Philip Thwaites, manager of process control for XPS Consulting & Testwork Services. “If you’re not efficient, you’re not going to be around. And our industry can be a lot more efficient.” According to Thwaites, measurement is the cornerstone of control and efficiency. “If you have a poor measurement, or no measurement, you can’t do good control,” he explained. But this is changing. More and more mining companies are conscious of improved measurements and endorsing control, automation and next-generation technologies. What is more, there has been significant progress in automated instruments recently. These measure crucial parameters in the processing circuit and equipment to allow operators to monitor and adjust process control as needed."
