GN has standard 14 inch and 18 inch diameter screw conveyor for option, also you can choose 2 section, 3 section, or 4 section ( maximum). Each Screw with electric motor and control panel, we also provide motor and control panel with IEC certification for option. The painting and material can also be choose, we have carbon steel, stainless steel and another much harder material than stainless steel for option. The installation tilt Angle of the Auger has 2 options, ≤5°or ≤40°. You can choose fixed speed or variable speed drive for the screw propeller.

The screw conveyor is a simple way to transport drilled solids. Screw conveyors are typically used to transport drilled cuttings from the shale shaker area to a discharge port, skip or to secondary processing equipment ( like drilling waste management system). The inside scroll( screw) also called auger, which is drived by a electric motor, drill cutting is fed into the Screw Conveyor and transported along by the rotating scroll.

Screw conveyor size and horsepower requirements will vary, dependent upon the length of the run, bit size, rate of penetration and flow rate. Additional sizes are available upon request. For detailed chart, pls contact GN solids control.

Screw conveyors, sometimes called augers or auger conveyor, are used as an efficient way to move a wide variety of materials. The auger is used to move material along a path using a helical screw. The process of drilling with a helical bit involves aspects of both: the creation of the hole with the tip of the bit is drilling, while moving the waste material out of the hole along the helical path is augering. Not all drilling involves augering (oil field drilling uses a pump to move the material). Screw conveyors in oilfield are often used horizontally or at a slight incline as an efficient way to move drilling fluids with drill cuttings.

Main components of Auger screw:

Motor, control panel, Screw( including blade and shaft),Conveyor housing, Supporting feet and saddles, Feed and discharge spouts, Cover, Through end, etc.

Screw consists of a several of blades of helix shape welded to a pipe or shaft. It moves the material. The following specs should be calculated carefully for proper use: Flight outside diameter, type of blades, spacing between the blades, thickness of the external diameter and interior shaft and rotation direction.
