Slurry Treatment System For Shield Tunneling Slurry

Published: 07/02/2016

Muck excavated by slurry‑shield tunnelling is conveyed using slurry as the medium. Soil cut by the cutter head mixes with slurry fed into the excavation chamber. The mixture is then pumped through pipelines to the on‑surface slurry‑treatment plant, where slurry‑processing equipment completes solid‑liquid separation.

For LZZG slurry treatment system: soil and gravel excavated by the shield machine enter the cutting chamber. Mixed high‑density slurry is pumped to the slurry treatment system. After processing, the cleaned slurry is pumped back to the excavation face for continuous circulation.

The typical slurry purification process involves slurry passing sequentially through vibrating screens, desanders, desilters and centrifuges to remove particles of different sizes step‑by‑step.

LZZG slurry treatment system integrates vibrating screens, desanders and desilters into one unit. Combining multiple functions in a single system, it delivers higher‑efficiency purification and recycling of shield‑machine slurry.
