ProcessMaster FEP500 electromagnetic flowmeter Hydrocyclone feed in the mining industry ABB ProcessMaster improves production, saves cost of maintenance and downtime in large zinc and lead mine. Measurement made easy — Using ABB’s ProcessMaster in hydrocarbon inlet feed lines — Introduction One of the world largest mines that produce zinc and lead concentrate with a high silver content, is located in Australia. Electromagnetic flowmeters are being used in the hydrocyclone inlet feed lines. Hydrocyclones are used for the classification on particles in slurries. Light particles are removed with the overflow stream by an upward swirling flow through the vortex finder, while heavier particles are removed with an underflow stream by a downward swirling flow. The particle size of the cyclone feed slurry ranges from 250 to ­ 500 microns leading to high abrasion. 1 In addition to this, the particles cause a high noise signal at the measuring electrodes resulting in a most challenging application for an electromagnetic flow

The measurement of the cyclone feed slurries has to be reliable, accurate and responsive to changes in the plant load. This enables to balance the plant load and plant throughput. Appropriate liner and electrode material selection combined with application engineering, enabled ABB to reduce replacement intervals significantly. ProcessMaster had been choosen as the flowmeter system resulting in Best-in-Class measurement and service life performance. In addition to this, the service life of the flowmeter is essential to minimize maintenance and replacement cost. The flowmeter sensor has to withstand...

— Customer benefits A protection ring at the inlet of the flowmeter maximizes service life of the sensor protecting the liner material from abrasion due to differences of the in inner diameter of the flowmeter and the connected pipe. Based on years of experience in the mining market, ABB provided the best in class solution. Maintenance and replacement cost have been minimized substantially. Material selection has allowed for an service life up to 3 years or longer. ProcessMasters most advanced filtering technology separates the signal from the noise without loosing responsiveness to changes of...
