These classifiers include:— a) Inclined Screw conveyor Classifiers: The said classifiers are assembly of open 'U' trough & screw having structural support at an inclination of about 10° to 40° with horizontal for refining raw material. Washing efficiency of any inclined screw is reduced particularly when slurry is required to be conveyed at an inclination.

The particles to be washed pass successively up the inclined tanks of several classifiers, while the wash passes through the classifiers in the opposite direction. In each classifier the pulp is diluted, mixed and rabbled, the particles washed, and the liquid removed resulting in a thoroughly washed and cleaned final product.
