The screw conveyor is designed to transport drilling waste from one place to another place safely and efficiently. There are many methods to transfer the drilling waste, but screw conveyor is a relatively economic and proven method among them. The benefits to use a screw conveyor is that low power consumption, continuous working which will reduce the requirement for collection tanks, require less operator to save labor cost, flexible to adjust the dimension for different transfer capacity. The scroll are made of wear-resistant and thicker manganese steel. the scroll can also be sprayed with wear-resistant coating to prolong the service life, the pull-wire switch can be installed on the conveyor to realize safety protection

The working principal of the screw conveyor is as below:
A scroll (also named auger) is rotated inside a trough driven by an explosion proof motor, when the drilling cuttings are fed into the inlet port of the screw conveyor and transferred along by the rotating scroll. The scroll is sealing inside the trough by a hinged metal lid/cover for safety.
The screw conveyor discharge port can be customized according to client’s requirement. The cuttings collection box can be installed under the discharge port for safe storage, or the high G drying shaker waste collection hopper, or the open top feeding port of the vertical cuttings dryer. The screw conveyor screw diameter and screw length can be customized as per transfer capacity and transfer distance requirement. the screw diameter could be 10 inch, 12 inch, 14 inch, 18 inch and the screw length could be 12ft, 24 ft, 36 ft, 48ft, each section is 12ft and you can select 2 section, 3 section, 4 section.


If you need a drilling cuttings transfer system, pls contact with GN solids control, we can design multi point discharge screw conveyor for container loading.
