For more than 35 years FLSmidth has been developing the QCX/BlendExpert product range to cover virtually any mix control scenario at a cement plant from quarry to bagged cement. QCX/BlendExpert software was developed to support a multitude of analysis techniques as well as basically every possible process lay-out. Several advanced control features have been added over the years. QCX/BlendExpert has successfully been applied in numerous projects with PGNAA - both for stockpile and raw mill quality control.

QCX/BlendMaster™ is built on QCX/BlendExpert technology, but is a leaner package focused on high frequency, on-line PGNAA based quality control. A QCX/BlendMaster application supports one PGNAA unit and one mix control task for either a stockpile or a raw mill. A QCX/BlendMaster project comes pre-configured for either a stockpile or a raw mill on-line analysis control set-up. The product supports all leading PGNAA brands and is configured with an ‘OPC DA’ interface to the general process control system. Compared to a standard QCX/BlendExpert solution it means reduction in LIMS style data presentation & reporting and high focus on QC support for high frequency on-line analysis.

A QCX/BlendMaster project also means streamlining of software engineering & configuration, so that a given project can be delivered within a short delivery time and with reduced on-site commissioning. QCX/BlendMaster controls the proportioning of raw material feed to a stockpile or a raw mill to obtain the desired chemical product quality with respect to chemical constraints and various process constraints. Data capture and subsequent optimization calculations are fully automatic. Upon completion of every few minutes´ analysis cycle, the mass balance accounting is updated and new optimal feeder set-points are calculated and passed on to the general plant control system.
Stockpile accounting and associated application specific accounting and control utilities are supported by the QCX/BlendMaster-Pile application module. Recent software developments offer unique accounting and graphic data presentation facilities. Raw mill control applications are handled by the QCX/BlendMaster-Mill application module, which comes with a dedicated operator UI including a selection of available short term reports & trends.
