The Blendscan Pile Online Automatic Blending System controls the quality of stockpiles based on GEOSCAN analyser measurements by automatically adjusting feeder proportions of the input materials (building mix).
Features of the Blendscan Pile Online Automatic Blending System:
Computes and filters on-line the quality (eg. LSF, SR, AR, liquid phase, oxides) of the building mix and the cumulated stockpile.
Corrects possible deviations from the target quality (e.g. LSF, SR, AR) for a target stockpile tonnage (batch control) or continuously (continuous control) end after each new GEOSCAN measurement by automatically adjusting proportions of the input materials (e.g. limestone premix, clay or marl premix, slag, slate, etc). Exact knowledge of the input material compositions is not required, only the main differences in quality between input materials.
Takes into account constraints such as limitations on input material proportions by a proprietary constraint control and optimisation algorithm.
Rejects anomalous readings due to short term upsets such as temporary stops of feeders or the GEOSCAN and stockpile changes.
Communicates with various devices (GEOSCAN, dosage controllers/feeders) via customised protocols (Industrial Ethernet, Profibus, OPC, etc.).
Visualises in real-time the quality corresponding to each layer in a stockpile layer plot (longitudinal stockpiles) or to each angular section in an angular section plot (circular stockpiles).
Offers a reliable user-friendly human-machine interface (HMI) to introduce the recipe (e.g. selection of input materials from a database, quality and tonnage targets) for the current and future stockpiles, view on-line, historic trends and alarms.
Generates electronic reports (either automatically; daily, monthly, yearly or manually; for a specific time interval).

Scantech International | Real Time Analysis of Bulk Conveyed Materials
Scantech is the world leader in the application of on-line real-time measurement technologies for bulk materials. Scantech has over 1,000 analysers installed in 55 countries. Founded in 1981, the company has grown from a small private company based in South Australia to a successful public enterprise with an international business focus.
The platform for the company's early success was the commercialisation of scientific instrumentation developed by the CSIRO and the University of Queensland, resulting in the highly successful COALSCAN range of real time coal analysers. Since that time, new technologies have been developed using in-house R&D resources, whilst continuing to seek suitable technologies from external sources.
The company has developed and implemented a Quality Management System (ISO 9001:2008 BV Certified), assuring its customers of quality, safety and reliability of its products, production processes and services.
