How It Works
The Nesans SWF Series Envo Wash operates on the principle of centrifugal sedimentation using hydrocyclone technology. Slurry containing sand, silt, and other fines is pumped into the hydrocyclone at high pressure. Inside the cyclone, centrifugal force drives the heavier sand particles downward to the underflow, while lighter fines and impurities are carried upward through the overflow.
The underflow, which consists of clean, classified sand, is then discharged onto a dewatering screen, where excess water is removed, resulting in a low-moisture, ready-to-use sand product. The overflow water, carrying the fine impurities, is directed to a settling pit or wastewater treatment system, ensuring minimal material loss.
By combining cyclone classification with efficient dewatering, the SWF Series delivers clean sand with reduced water usage, making it an effective and streamlined solution for sand washing applications in various production environments.
