Principle overview：
by the pressure of scraper panel, the slurry get further concentrate, the rake will scrape the slurry to the center of pool, the slurry will drop to the lower pool from discharge port. The distribution box will flow out the water to clean the bottom layer material. The overflow of bottom layer will return to the distribution box and flow out to the second layer to clean the material, the overflow of second layer will return to the distribution box and flow out to the upper layer to clean the material, then discharged from overflow outlet. The triple cleaned material will come out from bottom outlet.
Selection instructions：
low area required, limited power
Model Description：
The utility model is mainly used for overflow washing in the process of selecting gold cyanidation. It can also be used for Hydrometallurgy ,washing and dewatering operations in light and chemical industries.
