Custom Design Options for Equipment Safety and Integrity
Screw Conveyor Design Services
Screw Conveyor Ltd conveyors have been successfully utilised in the transportation of drilling waste for over 19 years.
We offer a traditional solution together with additional performance and INCREASED SAFETY options to cater for most drilling and environmental conditions.
The screw conveyor is designed to transport drilling waste from one point to another in a safe and efficient manner. For the ultimate in screw conveyor safety we have an Immediate Stop Brake (ISB) system which provides the only method currently available of bringing a screw conveyor to a complete standstill upon activation of the emergency stop button.
The ISB is an essential and, for some clients, mandatory safety improvement modification for our screw conveyors.
The drilling waste transfer is achieved by the use of a screw rotated inside the trough by an electric or hydraulic drive unit.
Drilling waste is fed into the screw conveyor and transported along the trough to a designated discharge point(s). The waste of offloaded by means of a discharge or chute.
Screw conveyors can be completely sealed and manufactured to suit site conditions.
Design options for screw conveyors include:
UHMW lined trough for conveying sticky or gumbo type materials
Fixed or variable speed electric drive, inverter control, hydraulic drive
Drive mounting patterns including dual drive systems, for vertical and horizontal system for overall size optimisation
Electric Motors are ATEX IECEx IP56 or NEMA UL
Winterised trough for Arctic conditions

Screw Conveyor Handling Capabilities
In general, most drilling waste can be conveyed or discharged with a screw conveyor. The specification standard is also easily tailored to suit:
damp, wet or sticky materials
materials prone to fluidisation
greasy, oily products
hot, cold, wet or aggressive environments
Material flow rate is controlled by varying the screw conveyor flight design, speed and percentage loading, but many other factors need to be considered when deciding on the type and specification of machine required. We offer a material test and analysis service to help determine the flow characteristics of materials with unknown or doubtful properties.
Screw Conveyor Technology and Expertise
Screw Conveyor Limited’s principle engineering technical staff draw on over 30 years of experience each in the global oil and gas industry.
We understand the operational and cultural requirements which are necessary to support our global client base. There are many screw configurations available today and many design parameters that need to be varied to produce a cost-effective and efficient design of screw conveyor.
Our exceptional approach to design and specification ensures that our machines are constructed to the highest standards of specification and build quality, built to our customers’ exact requirements
