Several Feeding Ways of KOSUN Vertical Cutting Dryer

The flow of cuttings into the VERTI-G cuttings dryer is PLC-controlled and continuously fed to yield optimum liquid/ solids separation. Once cuttings are introduced into the dryer’s charge hopper, widely spaced, independently adjustable flights continuously direct cuttings to the screen surface. Flights are tungsten carbide coated to reduce wear and ensure optimum tolerance.

Feeding system of the vertical cuttings dryer has been a problem for the operators, normally there are several ways for feeding:

1 vacuum unit or vacuum collection system for transportation of drilling cuttings:
Working together with diaphragm pump.

2 Screw Conveyor system:
Screw conveyor is composed of electric motor, gear box, screw or auger, bracket, coupler, feeding hopper, solids discharge port, cover, etc. They are often used horizontally or at a slight incline as an efficient way to move the drilling cuttings from solids control system.

3 Peristaltic pump
A peristaltic pump is a type of positive displacement pump used for pumping the drilling waste to the top hopper of the vertical cuttings dryer from the cuttings collection hopper.

The 3ways of feeding system may be adopted to different conditions according to the jobsite situation. When there is enough place and enough financial support, you can choose vacuum unit together with 2 units of screw conveyor, one is installed horizontally and the other one is installed inclined. But for compact design, hose shear pump might be an ideal choice.

The 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.
