New-generation analysis unit optimises raw mill quality

The new generation OLX900 OnStream XRF Analyser is an all-in-one unit containing the powerful MiniPal QC analyser along with state-of-the-art sampling and control equipment. The OLX900 makes on-line raw meal analysis quicker and easier for improved process control.

Over the years, the cement industry has seen a shift from the classic lab analysis scenario, where samples were taken to the lab to be analysed, to carrying out sample analysis on-line in the process area. With the OLX900, analysis can be conducted at the sampling point, reducing the time from sampling to analysis. And with better, faster analysis, feed changes to the raw mix can be made quickly, for a consistent, high quality product.

The OLX900 features the new MiniPal QC analyser, which is an energy-dispersive X-ray fluorescence spectrometer from PANalytical. With the MiniPal QC, sample analysis takes place in air – eliminating the need for helium gas purge – making the OLX900 easier to maintain than its predecessor, the OLX800.

And it’s versatile. The OLX900 can be integrated in an FLSmidth Automation QCX/OnStream® package solution including mix control, or operate as a stand-alone analyser unit. Since first coming to market in 1993, the QCX/OnStream has been modified to keep up with industry requirements. It now offers high-frequency sampling and X-ray analysis for tight, on-line chemical quality control of cement raw mix or other powder process streams. With the new OLX900, the QCX/OnStream performs even better due to a 50 percent increase in the sampling and analysis frequency and superior analyser performance.

Quicker sampling, better control
The OLX900 can prepare and analyse samples every four minutes – and when combined with the powerful QCX/BlendExpert mix control software, process control is tight. And one analyser can service two adjacent raw mills, or one raw mill and one kiln feed product stream.

Other benefits include:

• A reduction in homogenising requirements before and after the raw mill system
• Lower fuel consumption at the burning stage
• More consistent clinker quality
