Slurry Separation Plant Selection for Tunneling Projects

Many contractors focus on the tunnel boring machine (TBM) and the performance that can be expected from this machine. However, contractors easily can overestimate the capabilities of their slurry separation plant, resulting in the slowdown of the advance rate due to the inability of the plant to keep up with the amount of solids that are being generated by the TBM.Choosing the correct separation plants is as important as choosing the correct TBM for the tunneling project.Improper slurry separatoin plant will result in lost time and money to the contractor.It is important to plan ahead to have the properly sized and correct equipment in place before the start of the project.

 

           

Slurry Separation Plant

How to select a correct slurry separation plant, first of all,The slurry separation plant should be designed to accommodate the majority of the material expected to be processed. Due to the unknown factors that can affect the tunneling advance rate, the contractor must have adequate separation equipment to allow the contractor to move forward at an unimpeded rate when the tunneling conditions are favorable. Second, all components of the slurry separation plant such as shale shaker    desander  desilter  decanter Centrifuge  centrifuge centrifugal pump   mud cleaner   vacuum degasser   Hydrocyclone cone    mud agitator    flare igniter     submersible slurry pump  mud tank    mud gas separator  Jet Mud Mixer    mud mixing pump   mud gun  screw pump    Shale Shaker Screen    shearing pump   Vertical Cutting Dryer shall sized to maximum flow rate that can be anticipated by pumps being used to in the slurry circuit. Then build in 30 percent redundancy to allow for slurry inconsistency and wear and tear on cyclones and pump parts. Keep in mind that pumps are rated on water and “brand new” efficiency curves. Rates begin to drop quickly when wear is occurring.Thrid If the geotechnical data indicates a large amount of clay with high plasticity, then your efforts should be geared to centrifuges and polymer delivery systems. The more times that a solids particle is circulated through the system, the smaller the particle will become and the more expensive it is to remove.

If the contractor does not have experts on separation equipment, consult experts with the equipment manufacturers or an independent consultant. These people are trained and have the experience to alleviate many of the problems before they have a chance to occur. OGEM Solids Control is an leading slurry separation plant manufacturer in the world. It would be a good choice to consult with OGEM for your tunneling project.
