LZZG Ultra Sand Recovery Units use hydrocyclone recover fine sand that overflowing from the sand washing plants, generally, 0.04-3mm fine materials can be well recycled >95%, without additional chemicals. LZZG Ultra Sand Recovery Units are designed 30-350tph and produced final product with residual water content 10â??15%. This recycling units are suitable for aggregates, coal ,concrete, frac sand, idustrial sands, frac sand, and more. Working principle The overflow of washing machines(wheel washers or washer screws)is fed to hydrocyclones by slurry pump with high pressure. Most fine materials (+300 mesh) concentrated by hydrocyclones goes to dewatering screen through underflow exit. After dewatering, the hydrocyclone underflow turn to be a dryer materials, moisture content
