The rotary scrubber is an autogenous rotating drum scrubber, utilizing pebbles and rocks within the feed source to fracture and disintegrate clay, agglomerates and soft oxides. The scrubber spins slowly, similar to a giant washing machine. It churns the fines and oversize and water together, vigorously breaking up the soil matrix as well as liberating the target mineral from tough clay, schist’s and rock. Disintegrated material is homogeneously slurried within the drum, whilst the autogenous load is retained within the drum by reverse flights located at the drum discharge end. Slurry and washed oversize overflows the drum discharge throat to the concentric exit trommel.

This material is then passed on to the downstream process equipment which can be in various forms such as centrifugal Concentrator, spiral chute, jig etc.
