VERTI-G Cuttings Dryer could be Regarded as a Vertical Centrifuge

Vertical cuttings dryer could be regarded as a vertical centrifuge, the discharged cuttings transfered by the auger get into the Vertical cutting dryer from the opening on the top, under the function of centrifugal force produced by rotation of the screen module. Liquid flow out from the opening at the flank side while the solids discharged out from the outlet at the bottom of the cutting dryer. The discharged solids water content is around 3%, that means there is no flowing water, so it could be transported easily.

KOSUN VC-1000 Vertical cuttings dryer

KOSUN is the first one to bring in synthetical analysis technology and patent from Italy, as well as apply this technology to vertical cutting dryer. KOSUN’s vertical cutting dryer copes with oil-based and water-based problem in native country and foreign countries, which is also applied to maximally meet the demand for drilling waste processing on different working conditions. By using the equipment, oil-based drilling mud can get the same processing result with water-based drilling mud, which can 98% satisfied customers.

The vertical centrifuge makes its contribution with its innovative process after the shale shaker completes its task. Cuttings that pass over the shaker typically have an average of 30% to 50% ROC (Retention on Cuttings) when they enter the proprietary auger system and begin to cycle through the VERTI-G cuttings dryer. The initial processing is done with a vertical cutting dryer that utilizes centrifugal force to take advantage of their differing densities to separate the largest portion of the remaining drilling fluid from the cuttings. The processed cuttings are discharged from the vortex dryer into the adjacent shale bin, and then have an average ROC between 4% and 7% once processing is complete. This ROC percentage represents cuttings suitable for immediate disposal requiring minimal if any further stabilization. Processed waste material is lighter, less toxic and is a more cost-efficiency.
