Last week we delivered 1 set slurry processing system to customer for their TBM project. Tunnel boring is one very popular system to for the tunnel project , especially for some city subway building. In the boring program, it also need drilling mud to cool the rig machine and flush the solids ,and take it our from the tunnel. This will consume large water to mix the drilling mud. Drilling mud is very expensive and high pollution, it is very necessary to recycle it for reuse.
In this customer project, the job site is at downtown of city. The customer require our system to dryer the solids as much as possible to convenient transportation. And do not allow the liquid out of system and pollute the job site. This project is in winter, so we load all equipment into container to make sure the equipment will work under the best most adapt temperature. For this project, we recommend our GNLW764 Decanter centrifuge and chemical dosing unit .GNLW764 is the biggest Decanter model of GN, the diameter of centrifuge bowl is 760mm , and the length is 4 times of diameter. The wider bowl diameter means the Decanter can generate biggest G force under the same rotated speed. Actually, this model Decanter will generate 3000G force when the speed reach 2600 RPM. The discharged solids will be dry enough. The model Decanter capacity is 140m3/hour, we only need one unit to finish all the slurry processing job.
Except Decanter centrifuge, the automatic chemical dosing unit will mix flocculant and feed it into material. The tiny particle smaller than 5 um will combine into bigger particle by the flocculant influence. It will help decater centrifuge to separate out the solids and get more clarify mud. In the system , you may see the discharged solids from Decanter cent will be directly transfer away by screw conveyor. All the treating process need less labor work.
GN is good at provide the customized solution for drilling mud treatment, we have more than 15 years in this industry, if your project have demanded on our equipment, welcome to contact to us.
