2. Gravitational classifiers
2.1 Simple sedimentation classifiers
They consist (figure 4 ) of a sedimentation tank or vat with parallel walls and an open sloping bottom, fitted with a mechanical device that continuously agitates the suspension (pulp) while recovering the fraction of solids that have settled (underflow). They are most often used in a closed circuit with a crusher, or, in the case of aggregates, as an eliminator...
