Minerals & Mining – Robust instruments for harsh conditions

Solutions for the Minerals and Mining Industry

There is hardly any industry where industrial measurement technology proves it is worth its name as much as in the mining, minerals processing and building materials industry. Performing under the harshest operating conditions, any kind of measurement (flow, level, temperature, pressure) must be reliable and reproducible. One of the first applications was the use of electromagnetic flowmeters on dredgers for measuring the flow of abrasive slurries. KROHNE has since developed the devices continuously so they are now available in sizes up to DN 3000 and with a ceramic liner for the measurement of all kinds of slurries with high solid content. We also offer complementary instrumentation e.g. for fresh air or fresh water supply in mines. KROHNE provides instrumentation solutions from “pit to port”. Reliable instrumentation impacts on production costs, throughput and efficiencies for mining and minerals processing customers, these customers see value and invest in KROHNE technology that is engineered to meet their requirements.

The building materials industry is very similar in terms of demands. In addition to flow, level measurement plays a major role here. Bulk measurements are among the applications with the largest growth rates, but due to dust formation, debris cones or low dielectric constants they are as well seen as sophisticated measurements. KROHNE designed the OPTIWAVE and OPTIFLEX series specifically for these applications. Our FMCW radar has for example a signal dynamic range and bandwidth, which determines the correct level even of materials with low reflective properties.
