In the duplex type one set of rakes is moving up, while the other set returns. Spiral classifiers. This classifier uses a continuously revolving spiral to move the sands up the slope. They can be operated at steeper slopes than the rake classifier, in which the sands tend to slip back when the rakes are removed.
