KOSUN VERTI-G cuttings dryer improves overall cost-efficiency by recovering costly drilling fluid that is recovered from cuttings, as well as whole mud lost from shaker failure and rig motion. Further, the VERTI-G cuttings dryer produces lower waste volumes by generating dryer solids in both oil- and synthetic-base drilling fluid systems. The reduced waste volume can in turn dramatically reduce disposal costs.
VERTI-G dryer gives operators a critical advantage in meeting increasingly stringent environmental rules for cuttings disposal. The flow of cuttings into the VERTI-G cuttings dryer is PLC-controlled and continuously fed to yield optimum liquid/solid separation. Once cuttings are introduced into the dryer’s charge hopper, widely spaced, independently adjustable flights continuously direct cuttings to the shaker screen surface. Flights are tungsten carbide coated to reduce abrasion and ensure optimum tolerance.
In these operations, drill cuttings and associated waste fluids are collected on the rig in cutting boxes and then sent back to shore for disposal or treatment prior to disposal. Even when the discharge of drill cuttings offshore is still allowed. There is often now a requirement to collect and transport drill cuttings on the rig for secondary process such as vertical cutting dryer that will reduce the volume of drilling fluids associated with cuttings prior to discharge. In the drilling waste management or some similar works, screw conveyor or auger is a necessary part to convey materials from base ground to a higher position for further treatment.

Drilling Mud Decanter Centrifuge is Widely Used in Separating Smaller Solid
Decanter centrifuge can be used on drilling site to separate suspended solids with particle diameter larger than or equal to 2μm and treat the drilling mud and fluids. It serves as the last-stage drilling mud solids control equipment, applicable for treating unweighted and weighted drilling mud.
When used to treat unweighted drilling mud, centrifugal separation process is very effective for drilling mud with low solid phase. Decanter centrifuge of large treating capacity is suitable for such purpose. It can deal with 23~45m3 liquid each hour, processing 3~4t solid phase. The decanting centrifuge separates the drilling mud into underflow and overflow. The large quantity of useless solid phase contained in the underflow is discharged into waste pool, and the precious liquid phase is returned into the drilling mud tanks. Since the drilling mud with low solid phase can bring immeasurable economic benefits, the drilling mud decanter centrifuge is more and more widely used to remove the solid phase in unweighted drilling mud.
Decanter centrifuge is widely used in drilling mud separation to separate smaller solid particles after the equipment processing such as drilling mud shale shaker and drilling fluids mud cleaner or desander and desilter. Usually, decanter centrifuge is equipped with screw pumps or slurry pumps to feed drilling mud to the centrifuge. Correct and proper operation and good condition make sure that drilling mud decanter centrifuge operate ordinarily with high performance. Next, in this essay, expedient measures to maintain drilling fluids will be closely described by steps.

Working principle of Vertical Cuttings Dryer in Drilling Site
The Vertical centrifuge gives operators a critical advantage in meeting increasingly stringent environmental rules for cuttings proposal. The Vertical Centrifuge improves overall cost-efficiency by recovering costly drilling fluid that is recovered from cuttings, as well as whole mud lost from shale shaker failure and rig motion. Further, the Vertical Cutting Dryer produce lower waste volume by generating dryer solids in both oil and synthetic-base drilling mud system. The reduced waste volume can in the turn dramatically reduce disposal cost.
Wet cuttings enter the vortex at the top of the unit and fall into the inner separation area. The conical screen basket within the unit rotates, producing an increasing G-force as the cuttings are forced downward and outward of up to 360 times the natural gravitational force (G-Force). As associated mud separates from the cuttings under the induced gravitational forces within the unit, the openings in the screen allows recovered fluid to pass through and exit the unit.
The vertical cuttings dryer improves overall cost-efficiency, producing reduced amounts of extremely dry cuttings for disposal and recovering valuable fluid for reuse. It is effective with water-, oil- and synthetic-base drilling fluids. Offshore and onshore projects where the recovery of valuable drilling fluid from cuttings, as well as recovery of whole mud lost from shaker failure, rig motion and screen blinding are priorities.

KOSUN Vertical Centrifuge Uses Centrifuge Force to Dry Drilled Fluid
With the improvement of environment protection awareness of the public, in the drilling site, the advanced new technology are urgently needed in promoting the effectiveness of drilling waste management both in domestic and international drilling market.
The Vertical Centrifuge (VC) is a continuous screen type centrifuge with automatic feed control designed for liquid-solid separation. The Vertical Centrifuge is designed to recover the liquid phase of the drilling fluid from drilled solids by exposing the latter to very high centrifugal acceleration forces which improve fluid separation from the drill cuttings. By further clarifying the costly liquid phase which can be returned to the active drilling mud system, the machine helps save money on the expensive drilling fluids. Often shaker screens get clogged and, as a result, expensive mud is lost overboard. The Vertical Centrifuge system catches any lost mud and returns it to the active mud system. The recovery systems work well with diesel, mineral and synthetic oil based mud.
KOSUN vertical cuttings dryer uses centrifuge force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900 RPM. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation. KOSUN Cuttings Dryer has been done with strict balance testing for all major rotary components to minimize vibration & noisy.
