As the oil and gas exploration and production technology is improving day by day, the traditional mud recycling system is gradually replaced by automatic, systematic and close-looped mud recycling system. Cutting dryers is more and more used together with the solid control system in the drilling rigs to meet the critical environmental requirement. The cutting dryer can meet the environmental requirement and recover and recycle more material for reuse.

Among all of GN’s products, one of them is the star product, that is cutting dryer. No matter in the flow line for solid control or for waste management, it has shown great performance. There are two types of cutting dryer, fixed speed and VFD. GN can manufacture them according to different customer’s requirements and save money for customers. The screen bowl’s maximum diameter is 930mm. And there are three different kind of screens for your choice, 250 micron, 350 micron and 500 micron. The handling capacity is 30 to 50 tons per hour. Tungsten carbide protect the flights on the rotor from abrasive solids and ensure longer operation life. The special design of high pressure air knife can clean the basket screen automatically and easily, and avoid the screen to be blinded by the viscosity mud and water based mud. The flushing system with specially designed nozzles around the body of cutting dryer can avoid the liquid discharge channel being blocked by sediments. The lubrication system is electrically interlocked with the main motor starter to prevent machine operation in the event of low or no oil pressure to the gearbox. The VFD control panel can facilitate soft starting, fingertip control of the VFD system can change the motor speed and thus the G force can be changed to the working conditions. The VFD system is made by ABB or SIEMENS and it is explosive proof.
