Vertical Cutting Dryer Vertical cutting dryer is also called vertical drying centrifuge, be widely used to treat drilling cuttings from oil based mud（OBM） and synthetic-based mud (SBM). It is a core equipment of drilling waste management to reduce waste and increase drilling fluid recovery. By centrifugal force, solids drilling cuttings are pushed out by angled blades on bowl, drilling fluid is forced out through the screen openings. Oil content of drill cuttings after treatment by vertical cutting dryer is less than 5%.

The solids from the treatment by the vertical cutting dryer are discharged through (7), and the recovered drilling mud (5) enters into the drilling fluid mud tank (6). The liquid feed pump or screw pump (8) extracts the recovered mud which containing fine solid particles and supplies it to the centrifuge (9) for treatment. The solid part is discharged through the solid slag discharge port (10), and the treated drilling fluid returns to the mud system (11). BZ vertical cutting dryer advantage 1. The rotating speed can reach 900RPM, which can form a separation factor of 420G and effectively separate the liquid in the drilling cuttings; 2. The scraper is made of cemented carbide material, with long service life; 3. Each replaceable component has passed the dynamic balance test, to keep the balance of the whole machine after replacing the component; 4. Independent oil cooling system, equipped with scientific oil tank cooling system, to meet the use requirements in high temperature environment; 5. The discharge port can be equipped with a screw conveyor, which is convenient for conveying dry cuttings and keep the equipment continuous operation ; 6. There is an observation port on the conical top cover, which can check the wear of screen and spiral scraper at any time.
