Horizontal current classifiers such as mechanical classifiers, spiral classifiers, rake classifiers are essentially of the free settling type. Vertical current or hydraulic classifiers such as elutriators, hydrocyclones, hydrosizers are usually of hindered settling types. Sieve bends are also commonly used for classification. Hydrocyclone
