The mud recovery system is a treatment system integrating mechanical and electrical control. It is a system for screening, drying, separation, control and transportation of drilling cuttings produced by the five-level purification equipment of the solid control system to meet the requirements of mud recovery system. This system is mainly composed of dry screening tank, drying tank, drying shale shaker screen, drilling cuttings dryer agitator, underwater slurry pump, screw conveyor and support frame, electrical control system and lighting system. The surface coating of the system is durable, which can ensure that the system can be applied in the environment with large wear and corrosion.
