RAW MIX ANALYZER
FULLY AUTOMATIC, PERIODICALANALYSIS OF SINTER FEEDFULLY AUTOMATIC AND STANDARDIZED SAMPLETAKING AND ANALYSESThe new Raw Mix Analyzer is designed for the fully
automatic sampling and analysis of granulated sinterfeed. It eliminates the need for manual sample-taking,preparation and analysis.
INSTALLATION OF A ROBOTIC SYSTEM
The sample-taking robot and a configuration of analyzing
systems are installed in an enclosed space located directlyat the raw mix conveyor belt, where the material is charged
on the sinter machine. The robotic system automaticallytakes samples from exactly the same place in the material
stream, which guarantees fully standardized and consistentsample preparation and analysis.

AVAILABLE ANALYSES• Moisture content• Permeability• Bulk density• Other material properties (e.g. chemical, physical) also
possible
DATA PROCESSING
Samples are taken automatically at ten-minute intervals.
The results of the analyses of all measured data areentered into a Level 2 expert system to optimize processparameters. This expert system allows for immediate andcontinuous corrective adjustments of various processparameters, such as water addition to the sinter raw mix. Asa result, operation of the sinter plant is always optimized.

The main properties of the sinter raw mix are efficiently
analyzed in individual analysis stations, while additionalsinter samples are available for further testing purposes.
The analysis of other material properties is also possible,depending on customer requirements.
THE GOAL: AUTOMATION AND DIGITALIZATIONThe key words in industry right now are automation anddigitalization, which is why Primetals Technologies hasdeveloped a brand new generation of the sinter Raw Mix
Analyzer. The ambitious goal was to fully automate anddigitalize the sampling process and feed the resulting
data into Level 2 automation systems, combining the datawith process models and expert systems to maximize
productivity and efficiency.

VARIABILITY AND FLEXIBILITY
Continuous adjustments and design modifications ensurea stable and robust measuring system, including peripheraldevices and a sophisticated control unit.
Modular installation means that the system can be adjusted
according to customer requirements for sampling, layout,
and desired analyses.

MAIN BENEFITS• Standardized and automatic sample-taking• High and consistent sinter quality• Fast and automatic response to changing
process parameters• Increased plant productivity

ROUND-THE-CLOCK OPERATIONThe Raw Mix Analyzer is extremely robust and is designed
to cope with the harsh working conditions of a sinter plant.
It represents a further step forward in terms of improving
sinter process control for the production of high-quality
sinter.

• Optimized control of sintering process• Improved operator safety• Flexibility in selection of raw materials
Resulting in use of fine and ultra-fine iron ores.
