Classification
The classifier designs differ mainly in the mode of removing the underflow and the overflow slurries. Immersed spiral or rakes are generally used for underflow slurries and an open launder carries the overflow. Figure 13.1 is a sketch of a spiral classifier where the spiral conveyor is installed within the bowl. The spiral operates along the ...
