Working principle
The thickener is a solid-liquid separation device based on gravity sedimentation. It can concentrate the slurry with solid weight of 10%-20% by gravity sedimentation into underflow slurry with solid content of 45%-55%. The slow-running (1/3~1/5r/min) rake makes the thickened underflow slurry discharged from the underflow port at the bottom of the thickener.
