Bulk Material Handling Equipment for Conveying, Feeding, Elevating, and Flow Control

Improve Material Flow | Increase Reliability | Reduce Downtime

We help identify and implement the right KWS Manufacturing solution for bulk material conveying, screw feeding, bucket elevating, drag conveying, slide gates, live bottoms, hoppers, bins, and custom engineered material handling systems. From food ingredients and chemicals to cement, aggregates, agriculture, mining, wastewater, recycling, and other dry bulk materials, KWS equipment helps manufacturers improve material flow, increase production efficiency, and maximize process reliability.

KWS Screw Conveyors

Move bulk material from one process to the next.

Discuss My Application Engineering Guide PDF Design Worksheet PDF Product Details

Move bulk material from one process to the next.

Do you need to transfer material that is already being fed at a controlled rate?

KWS shafted screw conveyors move bulk material through an enclosed trough or tube using a rotating screw. Select the arrangement around the product, conveying route, and inlet conditions.

Typical application
Transfer powder from a feeder to the next process vessel.

Also known as: Shafted screw conveyors, auger conveyors, screw augers.

Materials & industries

Dry powders, granules and semi-fluid bulk solids. Typical duties include food ingredient transfer, chemical processing and mineral handling.

Screw conveyor or screw feeder?

KWS explains controlled transfer versus withdrawal from a flood-loaded hopper. See why inlet conditions and screw design matter when selecting equipment.

KWS application example

Copper powder transfer in a confined layout

An inclined screw conveyor collects copper powder from a grinder and feeds a bucket elevator. This KWS project illustrates how the transfer route and connected equipment can be designed around limited plant space.

What this equipment can help you do

Enclosed transfer

Review a contained conveying route between process points.

Flexible layout

Discuss horizontal or inclined arrangements and multiple outlets.

Material-specific design

Match wear surfaces, construction, and screw geometry to the duty.

How the process works

Receive the feed

Material enters at the agreed controlled feed rate.

Convey through the housing

The rotating screw moves product along the selected route.

Discharge to the process

Material leaves through one or more planned outlets.

Configuration & selection

Inlet condition: Confirm whether a separate device controls the incoming feed.
Route: Conveying length, incline, inlet and outlet positions, and access.
Material: Bulk density, size, moisture, abrasiveness, corrosiveness, and temperature.

Options to discuss

Trough or tubular construction
Screw profile and pitch
Materials, liners, and seals
Drive, supports, and discharge layout

Share your material, bulk density, throughput, conveying length, incline, and inlet conditions. Include a drawing or photos when available.

Plan your application review

Is a screw conveyor the same as a screw feeder?

A conveyor transfers material supplied at a controlled rate. A feeder controls withdrawal beneath a flood-loaded hopper or bin. Tell RTS how material reaches the inlet so we can select the correct approach.

What should I send for an initial recommendation?

Start with the material, operating conditions, capacity, installation dimensions, and the problem you want to solve. RTS will review the requirements with KWS and identify missing information before a final selection.

Can you review an existing installation?

Send the equipment model or serial number, photos, drawings, and a description of the issue. We can discuss replacement equipment, parts, or an application review.
