High-precision mixtures for Earth Pressure Balanced Tunnel Works
Rudransh Colloids provides specific foaming agents and a variety of other drilling fluid additives for EPB tunnelling. During this tunnelling method, the conditioning agents are directly injected to the front face through nozzles at the cutting wheel. They are then pressurized in the working chamber and transported through the screw conveyor. The main function of drilling fluids for EPB is to modify the overall properties of the excavated muck mass such as lubrication, plasticity, compressibility, and permeability. Our experienced mud engineers can support your team on site and help to choose the right conditioning fluids that will improve the working conditions of the TBM by limiting the cutting and mixing torques, reducing cutting tools’ wear, and increasing advance speed.
