Desanding plant also called slurry separation plant, it is widely used for micro-tunneling, TBM construction, Pipe jacking construction and piling construction etc. The desanding plant is much simple when compared with Solids control system or mud recycling system. Desanding plant normally consist of double deck shaker, desander hydrocyclones and transfer centrifugal pumps. As the job requirement is very different, desanding plant can work perfectly to meet the job request.
Oil & gas drilling adopt Piston mud pump (high pressure) to feeding the borehole, and piston mud pump is easy to wear by drilling fluids with coarse solids, and the maintenance of piston mud pump is much higher cost. However, Horizontal slurry pump or vertical slurry pump is normally works for TBM, Pipe jacking and Piling construction, and Slurry pump can work with drilling fluids with big particles. After separation by shaker & 10in cyclones, the recovered drilling mud can satisfy the work condition.
