The vertical cuttings dryer ensures high efficiency of separation of drilling waste and minimizes the content of drill cuttings during oil and gas drilling. The main function of vertical cuttings dryer is to recover useful oil-based drilling fluid, reduce the oil content (OOC) of the cuttings, and reduce the total volume of cuttings that will be finally processed in the thermal desorption unit. The recovered oil-based drilling fluid will be returned to the solids control system. KWCD930 series dryer is mainly used for oil-based sludge, KWCD930S series with direct drive and double motor can be used for oil- and water-based sludge.
Vertical cuttings dryer uses centrifugal force to dry drill cuttings. Stainless steel screen rotate “wet” slurries and increase rotation speed to 900 RPM with G-force up to 420G. The liquid is passed through the holes of the screen basket, while the "Dry" slurries are extracted through angular flights into the cyclone, whose speed is slightly slower than the rotor. Tungsten carbide protects the blades from abrasive particles and ensures long service life. This helps maintain constant gap between the scrapers and screen, which is critical for proper operation.
Vertical cuttings dryer KWCD930 is mainly used for OBM sludge, KWCD930S with direct drive & double motor can be used for OBM & WBM sludge.
Vertical cuttings dryer with direct drive KWCD930S, the newest generation with direct drive and dual motor, has powerful technological capabilities and can not only reduce the amount of oil-based drill cuttings, but also recycle water-based drill cuttings. It uses two motors to drive the sieve basket and scraper respectively. It realizes adjustable and controlled main shaft speed and differential speed through double frequency conversion speed control.
