OUTOTEC’S FEEDGUARD PRODUCT APPLIES ROCSOLE’S TOMOGRAPHIC PLATFORM OUTOTEC FEEDGUARD OUTOTEC FEEDGUARD, BASED ON THE ELECTRICAL CAPACITANCE TOMOGRAPHY (ECT) IS CAPABLE OF DETECTING EVEN THE SMALLEST VARIATIONS IN THE FEED MIXTURE. OUTOTEC FEEDGUARD The Outotec® FeedGuard provides easy and quick detection of uneven feed or feed blockages. It has low maintenance requirements (non-intrusive sensors) and it is based on a very accurate and reliable ECT measurement. An online measurement of feed distribution and ensuring that it is even and without blockages improves the oxygen efficiency of the process, decreases weak acid production and reduces the slag losses of Cu or Ni. The total mass flow of FeedGuard is very close to the total mass flow of the individual feeds, normally within 1 % error calculated over a fill cycle of the loss-in-weight feeder. THE FEEDGUARD SENSOR SPECIALLY DEVELOPED FOR THE FLASH SMELTING OR FLASH CONVERTING PROCESS IT IS INTEGRATED TO THE CONCENTRATE OR MATTE BURNER FEED INLET PORT AND PROVIDES THE MEASUREMENT RESULT TO THE CONTROL ROOM ONLINE ROCSOLE’S TOMOGRAPHIC PLATFORM STATEMENTS PETER BJÖRKLUND TECHNOLOGY MANAGER, OUTOTEC FINLAND OY ”Our aim was to increase the productivity of the concentrate burner and to provide an accurate mass flow measurement. As a base for our product we have been applying Rocsole’s tomographic platform to do the mass flow measurement. A measurement accuracy of 1% has been observed during the pilot project. This FeedGuard solution brings clear benefits to our customers like spotting disturbances and blockages during feeding. In addition to that a non-uniform feed is detected and can be corrected fast.” PASI LAAKKONEN CEO OF ROCSOLE +358 40 147 8797 [email protected] www.rocsole.com “We are glad Outotec has been innovative and applying Rocsole’s Tomographic Platform. Tomographic Platform is a cost-effective way to produce new applications.
