ReadiMoist CM 200
The ReadiMoist CM 200 Conductive Material Moisture Monitor is a direct, on-conveyor monitor for measuring moisture in conductive mineral materials.
Fast neutron and gamma transmission is the most representative technique for accurate total moisture measurement in conveyed flows as it fully penetrates the flow and measures continuously to provide an average analysis over each short measurement increment.
Real time data is provided to the plant control system to enable dry tonnage to be accurately calculated. Raw materials are typically handled by weight and any water content should be determined to ensure the true dry weight of the material is known and accounted for in transactions and processing.
The total hydrogen content is measured and this can also be used for other composition measurement benefits. The measurements can be combined with results of other measurement systems (such as GEOSCAN elemental analyser) to provide a more complete analysis.
In the minerals sector the ReadiMoist CM 200 is used in measuring materials not suited to moisture measurement through microwave transmission techniques. These may include metal sinters, magnetite rich ores and concentrates, metal concentrates with high conductivity, highly magnetic materials, e.g. pyrrhotite tailings, etc.
"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."
