Acumine OreCheck™
Overview
Introduction
AcuMine's OreCheck™ offers cost-effective protection for valuable ore pass infrastructure.
OreCheck™ provides real-time feedback on the level of ore in a pass, with reliability and accuracy surpassing all other instruments on the market.
OreCheck™ operates continuously, even as rock is fed into the pass, unlike methods which rely on contact with the ore.
OreCheck™ is not affected by air currents, temperature variations or dust which can cause havoc to ultrasonic-reliant techniques. And unlike laser-based tools, OreCheck™ works reliably in dusty environments (even when the tool itself is thickly coated with dust).
AcuMine's OreCheck™ achieves remarkable accuracy, thanks to its millimetre wave radar technology. The radar beam width is perfectly sized for a narrow ore pass (without reflection from the wall), yet the unit itself is surprisingly small.
Benefits of OreCheck™
- 350m-plus range
- highly accurate
- measures through a grizzly
- operates in hostile environments (extreme dust, moisture and fog)
- continuous real-time monitoring
- easily installed
- reliable, proven components
- can be integrated into the mine management system
Installations
Orecheck has been installed in varios mines in Australia and around the world, including Phelps Dodge, Freeport and Olympic Dam. A new trial is epected by the end of 2007 for Codelco in Chile.
