Screw conveyor system is widely used together with the vertical cuttings dryer system. The auger screw conveyer system can be used to feed cuttings to vertical cuttings dryer, and collection sands discharged from vertical cuttings dryer and then convey to cutting containers, trucks or other sand holding device.
GN Solids Control makes different sizes of screw conveyors to suits for different applications:
The auger diameter varies from 10 inch to 16 inch. There are 10 inch, 12 inch, 14 inch and 16 inch as standard size available from GN Solids Control.
Each size auger conveyor is with screw elements of length 12 ft for each section. The different sections of 12 ft. will be interchangeable. Transfer length can be 24 ft, 36 ft and 48 ft.
Screw conveyorsystem can be used together with other devices to suit for different applications.
Feeding type for Vertical cuttings dryer at rig site:
As the Vertical cuttings dryer is capable to treat the drilling cuttings discharged fromsolids control shale shaker, decander, desander or mud cleaner. It cannot be used to treat the soil discharged from decanter centrifuge. It is too fine to separate by theVG dryer screen basket.
In this case, at least 2 sets 36ft screw conveyer will be used in the rig side VG drying system:
Screw conveyor #1: It is in level to collect drill cuttings from solids control system
Screw conveyor #2: It should be inclined to collect cuttings transferred from #1 screw conveyor and convey to the VG dryer feeder hopper.
Screw conveyor to transfer drilling waste from waste pits or containers:
There should be a V-hopper on top of the screw conveyor to collection and buffer the drill cutting. And the screw conveyor is inclined to convey cuttings from the V-hopper to VG dryer.
However, the screw conveyor system is only suitable for the drilling cuttings with less liquid phase content. If the liquid content is high, screw conveyor cannot do. And it will cause leakage. Vacuum transfer pump will be used in case of the fluid content is high. It is a powerful 100% air driven pump suiting for a very wide range of applications.

Chinese Lunar new year holiday is coming in the corner. There is only 3 weeks before the holiday. As there will be no people working during the holiday. And there is no vessel for shipment during a whole month. GN Solids Control workshop is working day and night to ensure a timely delivery before the new year holiday. This week, 3 sets of mud gas separator is ready for shipment and will be ship to a France client soon.
Application and functions of mud gas separator
The mud gas separator is an effectively machine to prevent harmful gas from erosion, and ensure the safety of human and rig site equipment. It is also named poor boy degasser. When the drilling fluid is with air invasion, there will be a large deviation on drilling fluids proportion and viscosity, it cannot meet the drilling requirements. if the air invasion drilling fluids cannot be treated timely and properly, it will cause a surge, or even cause blowout accident. The combination of l mud gas separator and electronic ignition device can ensure the smooth operation of the drilling process.
The mud gas separator is used with choke manifolds to remove free gas from drilling fluids. And mud gas separator can be applied to underbalanced drilling and gas containing hydrogen sulfide. It is used to control liquid level and pressure of air invasion drilling fluids.
Besides mud gas separator, GN Solids Control offers complete solution on mud solids control and drilling waste management.
Mud solids control equipment GN Solids Control does offer:
Shale shaker, desander, desilter, mud cleaner, borate receovery decanter centrifuge, high speed decanter centrifuge, mud tank system, mud mixing system, mud agitator, various pumps etc…
