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.

Store material and deliver it reliably to the next process.

Do you need storage capacity, surge capacity, or a better discharge arrangement?

KWS designs hoppers, bins, and silos around the material and process. Storage volume, loading method, outlet geometry, and downstream withdrawal need to be reviewed as one arrangement.

Typical application
Buffer a variable incoming flow before a controlled-rate feeder.

Also known as: Surge bins, storage hoppers, day bins, bulk-storage silos.

Materials & industries

Surge and storage duties in wastewater, cement, chemical, mining and aggregate plants. Hopper shape, wall geometry, outlet and discharge equipment must suit the material.

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

Storage designed around material flow

Lightweight plastic fluff can bridge and compact during storage. In this KWS installation, the hopper and live-bottom feeder were designed together to support withdrawal across the discharge opening.

Hopper and live-bottom system for storing and feeding plastic fluff.

Hopper arrangement developed for lightweight recycled plastic.

What this equipment can help you do

Process buffering

Provide capacity between operations with different flow rates.

Discharge planning

Review outlet geometry and withdrawal equipment together.

Installation fit

Coordinate loading, supports, access, and available space.

How the process works

Receive material

Define the loading device and incoming flow pattern.

Store or buffer

Size usable capacity around the process requirement.

Discharge downstream

Match the outlet and extraction device to the material.

Configuration & selection

Capacity: Required usable volume and material bulk density.
Loading and support: Loading method, impact, structural loads, and installation environment.
Flow review: Material behaviour, storage time, outlet dimensions, and discharge rate.

Options to discuss

Hopper, surge bin, or silo geometry
Cone or mass-flow-bottom assessment
Structural frames and access
Integrated screw feeder or live bottom

Share your usable capacity, material properties, loading method, footprint, and downstream discharge requirement. Include a drawing or photos when available.

Plan your application review

Will a larger outlet solve bridging?

Outlet size is only one factor. Material flow properties, wall geometry, storage conditions, and the feeder interface all need review before recommending a change.

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.
