A large amount of mud containing sand and rocks will be produced during the construction of slurry shield and pipe jacking. In order to protect the environment and save water resources, it is necessary to carry out solid-liquid separation treatment on the shield mud. KOSUN can provide a complete set of shield slurry solid-liquid separation system. The main equipment includes: shale shaker, de-sander, desilter, bottom drying screen, slurry supply pump, slurry circulation tank, etc. Slurry shield and pipe jacking are often constructed in cities, and the user’s construction site usually requires small equipment footprint and high treatment efficiency.
With the slurry shield and pipe jacking construction, the slurry is continuously purified through the slurry solid-liquid separation system, and ultrafine particles will continue to accumulate, which will eventually affect the shield and pipe jacking construction. Moreover, after the construction of the shield and the pipe jacking is completed, the waste mud also needs to be dehydrated. At this time, the high-speed large-drum slurry separator decanter centrifuge can play an important role. Through mechanical separation or mechanical and chemical flocculation and separation, the ultrafine particles in the shield slurry can be effectively separated, and the clean water can be discharged for recycling or meeting environmental protection discharge requirements.
