FIG. 01 — VERTICAL SCREW CONVEYOR, GENERAL ARRANGEMENT
What Is a Vertical Screw Conveyor?
A vertical screw conveyor is an enclosed conveying system that moves dry bulk material straight up, using a rotating screw inside a vertical casing to carry material from a lower inlet to a discharge point above. It's a different tool from the horizontal screw conveyors most plants already run: vertical conveying puts more demands on screw geometry, speed, and how material is fed in at the bottom, so it has to be sized around the specific job rather than treated as a horizontal conveyor turned on its end.
Where it earns its place is in plants with limited floor space and a moderate lift to cover, moving cement powder, fly ash, or similar material between levels without a separate elevator structure. It's not the right tool for every vertical lift, particularly where capacity or height goes beyond what a compact screw can handle, and we'll say where that line sits later on this page.
How It Works
Bottom Feed
Material enters through the lower inlet from a hopper, bin, or an upstream horizontal screw conveyor.
Screw Rotation
The drive turns the screw at the speed set for that material and diameter.
Vertical Lift
The screw carries material up through the enclosed casing. Pitch and speed are chosen around the material's flow characteristics and the required capacity.
Top Discharge
Material exits at the upper discharge into a silo, hopper, bin, or the next conveyor in the line.
Where a Vertical Screw Conveyor Helps
These are the practical reasons plants choose a vertical screw over the alternatives, when the material and duty suit it.
Small Footprint
The vertical casing takes up little floor area, useful where space around the lift point is tight.
Enclosed Path
Material stays inside a sealed casing the whole way up, which helps with dust control and keeps the material contained.
Continuous Flow
Once the upstream feed and the conveyor are matched, material moves continuously rather than in batches.
Construction Choice
MS, SS304, or SS316 depending on the material and whether hygiene or corrosion resistance matters.
Straightforward Integration
Flanged inlet and outlet connections tie into hoppers, silos, bins, and other conveyors without much fuss.
Speed Control
A VFD can be added where the feed rate needs to track upstream or downstream equipment.
Where It's Used
Cement Plants
Cement powder and limestone powder moving between process levels.
Fly Ash Handling
Enclosed vertical transfer where the capacity and lift fall within the conveyor's range.
Chemical Industry
Chemical powders, with construction chosen to suit the material.
Fertilizer Plants
Fertilizer powders and granules between processing, blending, and storage.
Mineral Processing
Limestone, gypsum, calcium carbonate, and similar dry bulk materials.
Food Processing
SS304 or SS316 for flour, sugar, salt, and starch where hygiene matters.
What It Can Move
Vertical screw conveying works best for dry, reasonably free-flowing powders and granules. Whether a specific material is a good fit depends on flowability, bulk density, moisture, particle size, and temperature, not just what category it falls into.
Cement Powder
Fly Ash
Limestone Powder
Gypsum Powder
Calcium Carbonate
Certain Fertilizers
Chemical Powders
Flour, Sugar & Salt
What doesn't work well: sticky or wet materials, large lumps, and very light, fluffy materials tend to be a poor fit. If you're not sure where your material falls, send us the details and we'll tell you honestly whether a vertical screw is the right call.
Technical Specifications
Each conveyor is sized against the actual material, required throughput, bulk density, and lift height, not picked off a size chart.
| Conveyor type | Vertical screw, enclosed casing |
|---|---|
| Standard diameter | 150 / 200 / 250 / 300 mm |
| Standard lift | Up to 15 m |
| Screw pitch | Short pitch, set per application |
| Screw speed | Set by material, diameter, and required capacity |
| Construction | MS / SS304 / SS316 |
| Drive | Direct drive or geared motor |
| VFD | Available where speed needs to be adjustable |
| Power supply | 415 V, 3 phase, 50 Hz |
| Inlet / outlet | Flanged, sized to the application |
A note on capacity: diameter alone doesn't tell you the TPH. Bulk density, required throughput, lift height, screw geometry, and speed all factor in, which is why we ask for these details before quoting rather than pricing off a diameter chart.

How to Select the Right One
Six pieces of information get you a real specification, not a guess. Work through them roughly in this order.
Vertical Screw Conveyor vs Bucket Elevator
Both lift bulk material vertically, but they're not interchangeable. Which one fits depends on capacity, lift height, the material itself, and how much floor space you actually have.
| Factor | Vertical screw conveyor | Bucket elevator |
|---|---|---|
| Floor space | Compact casing footprint | Needs boot, casing, and head arrangement |
| Typical duty | Powders/granules, moderate lift and capacity | Higher capacity, taller lifts |
| Material contact | Screw contact | Bucket carrying |
| Lift on our standard range | Up to 15 m | Engineered for substantially greater heights |
| Best fit | Compact, enclosed, moderate duty | Higher capacity or taller lift |
Neither replaces the other across the board, it depends on the application. If your numbers point toward higher capacity or a taller lift, a bucket elevator is worth a look. Explore Bucket Elevators →
What an Installation Looks Like
Representative scenarios based on typical project parameters, not specific named projects.
Inter-Floor Cement Transfer
A plant moving cement powder between process levels, where the lift and required capacity fall within a compact 200–250 mm MS conveyor's range, rather than justifying a separate elevator structure.
Corrosive Powder Handling
A chemical process moving powder vertically where SS304 or SS316 construction is specified for corrosion resistance, and enclosed conveying keeps the material contained.

Why Choose Neo Conveyors
We've been building conveyor systems since 2007. For a vertical screw conveyor, that means sizing it around your material and duty rather than adapting a standard part and hoping it fits.

FAQs
What is a vertical screw conveyor?
An enclosed screw-based conveying system that transfers dry bulk powders and granules upward from a lower inlet to a higher discharge point.
What materials can it handle?
Common applications include cement powder, fly ash, limestone powder, gypsum, some fertilizer grades, chemical powders, mineral powders, and food ingredients such as flour, sugar, salt, and starch. Suitability depends on how freely the material flows and its moisture content.
What diameters are available?
Standard diameters are 150, 200, 250, and 300 mm. Final selection depends on required capacity and the material's properties.
How high can it lift material?
The standard range covers lifts up to 15 metres. For taller lifts or higher capacity, a bucket elevator is usually worth evaluating alongside a screw conveyor.
Can it be made in stainless steel?
Yes, SS304 and SS316 are available where corrosion resistance or hygiene requirements call for stainless construction.
How is it sized?
Sizing takes into account the material's bulk density, required capacity, lift height, screw diameter and pitch, operating speed, and drive requirements.
Is a vertical screw conveyor better than a bucket elevator?
Neither is universally better. A vertical screw conveyor suits compact, enclosed, moderate-duty applications; a bucket elevator is usually the better fit for higher capacity or taller lifts. The right choice depends on the full application.
Can it be customised?
Yes, diameter, screw geometry, construction material, drive type, and inlet/outlet arrangement are all specified per project.
Do you provide installation support?
Yes, installation and commissioning support is available across India; the exact scope is confirmed for each project.
