KOSUN KD-425 slurry treatment system for mud balance shield is of modular structure design, which is specialized for mud purification in medium slurry balance shield construction projects.

The KD-425 system consists of scalping shaker module, desanding module and desilting module. Equipped with coarse-mesh screens, the scalping shaker module is used to remove big particles. The desanding module is equipped with two desanding cyclones, and the desilting module is equipped with six desilting cyclones, and a dual-deck shaker is used as the underflow shaker for desander and desilter respectively.

The mud falls into the collecting box via scalping shaker, and then is conveyed to the desanding module through a connecting trough. The desanding module is equipped with a desander having two 18” cyclones in diameter and is capable to remove sand from the mud. The desilter with six 6” cyclones in diameter can further separate the mud as required.
