An inclined spiral mechanism used for wet classification based on sedimentation rates.
● Separates ultra-fines and slimes from usable sand fractions.
● Commonly used in silica beneficiation and clay removal stages.
Features: Adjustable screw pitch and speed, overflow weir, settling tank.
Benefits: Enhances purity, improves yield consistency, and reduces downstream load on dryers and screens.
Our Screw Classifier is a precision-engineered system designed for wet classification of sand and slurry based on sedimentation rates. Using an inclined spiral mechanism, it separates ultra-fines and slimes from usable sand fractions—enhancing product purity and reducing downstream load on dryers and screens.
● Design: Adjustable screw pitch and speed, overflow weir, settling tank
● Function: Sedimentation-based separation of fine particles from coarse sand
● Applications: Silica beneficiation, clay removal, mineral washing, slurry classification
● Benefits: Improves yield consistency, reduces moisture carryover, and enhances downstream efficiency
