KOSUN Screw Conveyer can be used in Drilling Waste Management Projects

Nowadays many more environmental regulations limiting or banning the discharge of various types of drilling fluids and associated drill cuttings globally. The drilling contractors started to utilize "zero discharge" or "ship to shore" drilling operations. 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 cuttings 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.

A screw conveyer or auger conveyer is a mechanism that uses a rotating helical screw blade, called a “flighting“, usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat, bone meal, municipal solid waste, and many others. The design of the conveyor is dependent on operating conditions, the type of transported material and its properties. Traffic enforcement can be controlled by changing the speed of propulsion.

KOSUN screw conveyer can be used in drilling waste management projects, providing an effective, low-cost drilling cuttings transport system for onshore and offshore drilling facilities. Adopting 12-feet (3.66m) multi-sectional composite structure, the screw conveyor can be flexibly assembled on different drilling sites, with characteristics of simple operation, stable structure, strong adaptability and high safety, so as to significantly improve the working efficiency of equipment and reduce the costs and resources. The blade of screw conveyor adopts wear-resistant material to ensure its service life. The screw conveyor is designed on basis of strict safety standards. Grille shield is provided on its U-shaped chute to prevent foreign materials from entering, to guarantee the operator’s safety. The frame at bottom can protect and support the screw conveyor, ensuring its structural stability.
