MINING & PROCESSING INDUSTRY

MEASUREMENT SOLUTIONS FOR MINING & MINERAL PROCESSING APPLICATIONS

Our product range for the mining industry includes non-contacting, radiometric level gauges and radiation based belt weighers. Gamma densitometers from Berthold are widely used for the concentration measurement on all kind of slurries and suspensions e.g. in coal washing plants. As technology leader in nucleonic measurements, Berthold provides a wide range of analyzers and measurement solutions that have been specifically designed for coal and ore mines and their preparation plants. Based on 30 years of experience in microwave technology, Berthold provides also online moisture analysers that are able to measure in a non-contacting manner highly accurate and very representative directly on the conveyor belt.

The experts for measurement solutions

All products are characterized by an excellent measurement accuracy, repeatability and above all mechanical ruggedness to withstand the harsh conditions of the mining industry for several years – even decades without the need of recalibration or maintenance.

State of the art technology

Outside mounting of components
Not exposed to the harsh process conditions
Free of wear and maintenance
Smooth handling and operation
Lowest cost of ownership
Easy to install on existing vessels, pipelines and conveyor systems without modifications
Perfect for all high temperature and high pressure applications

Do you need a measurement with an extremely short reaction time?

The LB 480 SpeedStar can be used where reaction times in the millisecond range are required. While standard measurements calculate a new measured value every 500 ms, the Speedstar version with a measuring time of 50 ms is 10 times faster. This allows very fast object recognition, e.g. detecting the beginning of a steel plate being moved at a relatively high speed on the roll conveyor, or measuring a density profile on pipes or plates detected directly during extrusion. The level of gas bottles can also be measured while the bottles are still being transported.

MINING & PROCESSING INDUSTRY — THE APPLICATIONS

Measuring the potassium content for the potash industry

Potassium content measurement for the potash industry is a very difficult and challenging measurement. It is a necessary component of the production process and essential to the efficient production of potash. Potassium contains the radioactive isotope K-40. This isotope is only found in extremely small quantities in the ore itself. The detection of the K-40 requires an extremely sensitive and superior stable measurement system, which must be capable of suppressing the inherent background radiation in order to obtain an optimal signal-to-noise ratio. Through the detection of K-40, the concentration of K₂O or KCl can be measured. Berthold has the perfect solution for the challenging task providing accurate potassium measurements with the potassium analyser LB 474.

Measuring the concentration for dedging applications

Berthold has the solution for this difficult measurement. The radiometric density measuring system from Berthold is used for online monitoring of the solid concentration. Extreme measuring conditions like vibration, weather or varying particle size and composition don’t effect the measuring performance. Due to the sophisticated stabilization of the detector performance, the highly accurate measuring results are guaranteed for many years of operation and no maintenance is required at any time. With thousands of systems in operation worldwide, the LB 474 has proven to be a reliable measuring solution for dredging applications, providing high levels of accuracy and operational safety.

Measuring the solids content in the thickener

Large volume thickening tanks are used in mining to concentrate the ore or minerals contained in sludge. Solids settle on the bottom of the thickener and from there they will be removed from the vessel via an underflow outlet. The sludge leaving the thickener should have a fairly high solids content. However, pumps and pipes can become clogged if too many solids are withdrawn at once.
The solids content in the underflow is monitored continuously by the radiometric density measurement SmartSeries LB 414. The robust stainless steel device provides reliable measurements with excellent accuracy and reproducibility over many years. The integrated control panel allows for easy and quick start-up. Measured values are displayed on-site.
