Iron
Ore
A large Western Australian Iron Ore mine processes iron ore to
produce both a lump and fines product which is then delivered to
the Dampier loading facility. A MoistScan® MA-500HDi was trialled
on the product conveyor belt which produces their fines product.
The MoistScan® MA-500HDi was designed to provide product
moisture measurement in deep bed depth & high attenuating
material such as iron Ore.
An exhaustive trial program involving comparative analysis of in
excess of 300 physical samples with the MA-500HDi trial unit,
resulted in a decision to retain two(2) MA-500HDi units for the
online moisture measurement component of the plant
reconciliation plan.
The analyser was proven to have an accuracy of approximately
0.6% total moisture with a product bed depth of 350mm over a
moisture range of 8.0% to 14%.
