APPLICATIONS FOR MINING INDUSTRY

ONLINE AND INLINE ANALYZERS AND SENSORS FOR PROCESS AUTOMATION

Online Analyzers for Mining Industry. Sensors for Process Automation. In mining applications SensoTech systems are the perfect solution for diverse measuring tasks. First of all, from copper mining to potassium chloride flotation LiquiSonic® monitors saturations. Also, concentrations and suspension densities. Hence, Numerous customer requests always lead to more and more new measuring tasks and applications.

Sonic velocity measurement in KCl-suspension

Online Analyzers for Mining Industry. Sensors for Process Automation.

Typical separation processes for NaCl and KCl are:

Flotation

Electrostatic separation

Hot dissolution process

LiquiSonic® systems can easily be adapted to accommodate various modified process conditions. In addition, the Controller software manages up to 256 various product characteristics.

Sensors for Process Automation.Depending on the user access rights, these characteristics may be activated after the sensor replacement or when process conditions change. As a result, this concept ensures the return on investment. And, decrease the response time on changing boundary conditions. For new applications, a complete new calculation model can be created by using process reference values.

More over, The LiquiSonic® analyzer provides a precise inline concentration measurement with real-time monitoring. An automatic concentration-regulated process control prevents the plant from being „blocked“ (process control is too slow) and increases the process yield and productivity. The robust sensor construction and the optional special materials, like titanium, promote long process life.

Additional advantages are:

· Optimum line control and reliable process data
· Increasing the efficiency of clarifier and thickener
· Drift free measurements over years
· Early recognition of malfunctions in a matter of seconds
· Reduced material and energy consumption and costs
