When we mentioned cutting dryer, there are always 2 explanations. One is for High H dryer (Hi-G dryer), or even named as high H shale shaker or cutting drying shale shaker. Its normally used for water structured mud drilling cuttings. It is just a special designed shale shaker with high G force or older to 7. 5 or maybe 8. And the G pressure is adjustable to suit for further applications. High G cutting dryer is with a longer screen deck and screen region, mostly 4-panel.
Another kind of cutting dryer is vertical cuttings dryer (short name while VG dryer). Vertical Cutting Dryer uses centrifugal drive to dry drilled solids through OBM or SBM. A stainless-steel screen bowl traps “wet” solids and make them improve to 900RPM with Gary the gadget guy force to 420G. It may also offer super high speed 1200RPM with G force in order to 750G. Liquid is obligated through the screen bowl open positions, while “dry” solids usually are extracted by the angled routes attached to the cone, which often rotate slightly slower compared to bowl. Tungsten carbide floor welding protects the routes from abrasive and makes sure long operational life. The objective of this is maintaining a constant hole between the scroll and screen bowl, which is very important intended for proper operation.
In some cases, when folks only mentioned cuttings dryer or cutting dryer, is actually means High G dryer shale shaker. And Top to bottom dryer is for vertical cuttings dryer.
Other waste management equipment used together with cutting dryer
High speed Decanter centrifuge
No matter high G dryer shale shaker or straight cuttings dryer, after that, decander centrifuge should be accustomed to separate the fine solids from the recoveried fluids. 14’’ decanter centrifuge is the most well-known size. 18 inch and also 22 inch big serving is also normally used for huge capacity. It is usually mounted on any telescopic skid and provided by a screw pump.
It is used to exchange drilled cuttings, feed with regard to high G dryer shale shaker, vertical cuttings dryer. It can also used to transfer typically the drilled solids discharged coming from dryer to the collection location.
