Vertical Screw Conveyor (Vertical Auger Conveyor)

Introduction

Vertical Screw Conveyors elevate bulk materials in a compact, enclosed system with minimal moving parts—perfect for steep inclines up to 30 ft (9 m). They're cost-effective, versatile, and widely used in industries like chemicals, food, agriculture, minerals, wastewater, and pulp & paper.

Specifications

Parameter	Typical Range / Details
Orientation	90° vertical transport, optional short horizontal infeed
Capacity	Up to ~6,000 ft³/h (≈170 m³/h)
Elevation (Lift)	Up to 30 ft (9 m) standard
Construction Material	Carbon steel, SS304/316; options for alloys or abrasion-resistant lining
Drive System	Gearmotor + shafted or shaftless screw; TEFC motor; VFD optional
Design Options	Shaftless augers for sticky materials, tubular or U-trough housing
Inlet/Outlet	Customizable side-entry or inline inlet sections

Ideal Applications & Industries

• Chemical & Minerals – Powders, sludge, fly-ash
• Food & Agriculture – Grain, feed, flour, sugar
• Wastewater & Biosolids – Dewatering sludge lift
• Wood & Paper – Chips, shavings, sawdust
• Pharma & Powder Processing – Hygienic meet-infeed to process lines

Key Features & Benefits

1. Compact Footprint – Vertical lift saves floor space
2. Enclosed Design – Dust-tight operation ideal for hygiene or environmental control
3. Low Maintenance – Minimal wear, few moving parts, no bucket chains
4. Versatile Handling – Free-flowing to lightly sluggish materials; shaftless designs for sticky content
5. Multiple Inlet/Outlet Options – Feed from several points; combine with batching/feeder systems
6. Built Tough – Stainless or alloy options, abrasion resistance, and sealing for harsh materials
