Except for GNLW363CG star product centrifuge, we also have yet another Vertical cuttings dryer along with super working performance to get drilling waste management. Due to oil show higher cost, most of us only take the centrifuge right now there. Below chapter to give more info about GN vertical cuttings dryer

1 . GN Solids Control top to bottom cuttings dryer is to officially used on line / off brand drilling waste management, mostly to treat the drilling cuttings discharged from shale shaker, to separate the solids in addition to recycle the valuable oil-based drilling mud for using again
2 . GN vertical cuttings dryer is mainly used for oil-based mud drilling cuttings therapy. The oil on cuttings (OOC) can be reduced to help 3% to 5% following GN vertical cuttings dryer. The discharged dry solids can be transported to energy desorption unit for ultimate treatment. The clean drilling mud can be transfer in order to high speed decanter centrifuge to find the fine solids, so the mud density might be lower down which make it right for reuse
3. In the event that for water based drilling waste management, we highly recommend fixation unit or renforcement unit for final cure.
