Screw Conveyors
Economical and Reliable Handling
Screw conveyors represent one of the oldest and most cost-effective methods for handling semi-solid bulk materials like drill cuttings.
Optional Features for Enhanced Control and Safety
Optional features include push-button electric start and speed control, safety gates, and an emergency stop device, allowing for enhanced control and safety during operation.

Contact your PSI representative to discuss your specific requirements and configure a system that perfectly suits your needs.
Customizable Conveyor
The PSI conveyor system consists of a range of stock components designed for easy assembly into custom configurations tailored to your specific material handling needs.
Rugged Drive Sections
Our drive sections feature robust motors and gearing specifically chosen to handle the weight and density of your materials effectively.
Durable Construction
All troughs are constructed from heavy-duty steel plate coated with industrial-strength epoxy paint, ensuring longevity and durability. Sealed hanger and end bearings support the steel auger, minimizing wear over time.
Super-Duty Coupling Shafts
Super-duty coupling shafts connect the auger between sections, providing seamless operation and preventing material spillage.
ENHANCED SAFETY OPTIONS
- Top mounted safety grates
- Remote stop switch
- Strobe light and alarm horn
- Side mount emergency pull cable
FEATURES
- Drive Section: The conveyor section has the gearbox and motor mounted either directly to it, or in closest proximity. This section consists of the drive and all of its components, such as the trough endplate, screw, trough and cover. For a pulling conveyor, a discharge spout is fixed to the trough, typically close to the drive, to maximize the conveying length.
- Midsection: The conveyor section couples to the drive section when three or more sections are joined together. The midsection consists of a trough, screw, cover, hanger frame, hanger bearing and coupling shaft. The midsection contains the least number of parts.
- Tail Section: The tail section is the “terminal end” of the system. It has a discharge spout when set up as a pushing system. This section is farthest away from the drive section and follows the midsections. The tail section consists of all the same components as the midsection—plus a trough end flange, waste pack seal, tail shaft and the idle end bearing. The idle end bearing can be mounted either directly to the trough endplate, or a pillow block bearing can be used.
Screw Conveyor Applications: Industries We Serve
Screw conveyors remain one of the most economical ways to move material that is too wet for a belt and too solid for a pump. PSI conveyors are working in these applications today.
Oil & Gas: Petroleum Material Handling Solutions
On the rig, a drill cuttings screw conveyor collects solids discharged from shale shakers, desanders, desilters and centrifuges and carries them to a catch tank, cuttings box or treatment unit. PSI conveyors are configured for the density of wet cuttings and can be supplied with UL explosion proof or ATEX/IECEx drives and controls for classified areas around the mud system. Pair them with shaker screen cleaners and MAX2000® mud agitators for a complete drilling fluid handling package.
Drilling Waste Management and Zero Discharge Operations
Where cuttings must be fully contained, PSI’s 360° conveyor swivel gives you a rigid, fast acting discharge that can be pointed at multiple bins or skips without moving the conveyor. The swivel is available manually or pneumatically operated for clean, efficient cuttings discharge, and slide gate discharges let a single conveyor feed more than one location.
Mining and Minerals: Bulk Material Handling Equipment
Mining operations use screw conveyors to meter and transfer bulk solids, fines and dewatered material between process steps. PSI builds each screw conveyor for mining around the material’s weight and density, with heavy duty 3/16″ steel troughs, cold rolled steel shafts and CEMA standard components.
Industrial Processing and Manufacturing: Industrial Screw Conveyors
Plant managers rely on industrial screw conveyors to feed, transfer and distribute bulk material between mixers, hoppers and process units. PSI offers fixed or variable speed drives, slide gate discharges for multiple drop points, brake motors for instantaneous stopping, and custom control panels that run two or more conveyors from one unit.
Environmental Remediation and Waste Solids
Remediation and treatment projects need equipment that can be set up fast and moved when the job changes. Modular 6 ft and 12 ft sections, standalone or integrated configurations, and angled conveyors that run both horizontally and inclined make PSI conveyors practical for temporary and permanent solids handling layouts.
Why Choose PSI as Your Screw Conveyor Manufacturer
Process Solutions International (PSI) designs and manufactures industrial screwa conveyors that move semi solid and bulk materials horizontally or at an incline with steady, predictable flow. Each PSI screw conveyor system is configured around the weight and density of the material you are handling, so the trough, screw, drive and controls are matched to the job rather than pulled off a generic shelf.
• Made in the USA by Process Solutions International, an ISO certified manufacturer serving drilling, mining and industrial customers worldwide since 1991.
• CEMA standard components on every conveyor, so wear parts are familiar to your maintenance team.
• Hazardous area ready with UL explosion proof or ATEX/IECEx drives, starters and emergency devices.
• Engineered, not generic. Each conveyor is built around your material’s weight and density and your site layout.
• Documentation that helps your crew. Installation, operation and maintenance manuals are available for download.
