The Reflux Classifier® (RC)

The Reflux Classifier® (RC) from FLSmidth is state-of-the-art technology now poised to revolutionise fine mineral beneficiation in the African mining and minerals processing industries. Already proven in gravity-based separation engineering in Asia, Australia and North America, RCs are the next generation of fine coal and mineral processing equipment.

There are currently seven RC installations in South Africa and the FLSmidth team has started design work on the biggest RC units in the world — four RC3000 units each capable of treating up to 250 tons per hour (tph) — for a coal project in Mozambique. At the same time, FLSmidth is conducting test work for southern African customers in the mineral sands, coal, iron ore and copper sectors, as part of its commitment to expanding RC technology into a variety of different mineral applications and raising awareness of the process and cost benefits in existing markets.

“The addition of RC technology through FLSmidth’s 2012 acquisition of Ludowici has ideally positioned us to provide equipment, services and technical support to African coal operations as a single source supplier with a complete coal processing flow sheet from run of mine to final product,” says Terence Osborn, capital sales and marketing manager of FLSmidth.

“The RC units have effectively eliminated the need for the spirals and taken over some of the function of the hydrosizers, while requiring a footprint and building structure a fraction of the size required by conventional equipment,” Osborn says.
