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.

Main Features of Desanding plant
Double screen shaker with much higher purification efficiency, convenient operation and reliable performance
Reasonable design with the function of preventing dry pumping, effectively improve the lifetime of slurry pump.
The polyurethane hydrocyclone is selected with better anti-abrasive performance
Full purification of engineering mud, help to improve the drilling quality and avoid sticking accident
Effective separation of soil slag, help to improve the efficiency of hole-making
Mud recycling, recover and reuse, save drilling fluids cost and helpful the final mud discharge
Closed-circuit slurry purification reduce the impact on the environment
