Reliable Screw Conveyors & Precision Feeders

At Cosben Engineering, conveying and feeding systems are never treated as off-the-shelf equipment, they are designed as part of a working process. As an industrial screw conveyor manufacturer and OEM, we build screw conveyor systems for bulk powder handling that operate reliably in real plants, through long shifts, varying loads and everyday operating challenges.

#FAQ

Frequently Asked Questions

What materials can be handled using screw conveyor systems?

They work really well for a wide range of powders, granules, flakes and semi-free-flowing bulk solids. You will commonly see them handling things like cement, fly ash, lime, chemicals, minerals, plastics and animal feed, as well as food ingredients like flour.

How do I choose between a screw conveyor and a pneumatic conveying system?

It usually comes down to distance and layout. Screw conveyors are great for short to medium distances, especially when you need a controlled discharge and want to keep energy costs down. On the other hand, pneumatic systems are ideal for longer distances, completely dust-free transfers or complex layouts that require flexible routing. Ultimately, the best choice depends on how your material behaves, your plant layout and your specific process needs.

What is the difference between a screw conveyor and a screw feeder?

The main difference is their purpose. A screw conveyor is simply built to move material from point A to point B. A screw feeder, however, is specifically designed to control and regulate the flow rate, which is essential when you need precise dosing or a consistent feed.

Are vertical screw conveyors suitable for heavy or abrasive materials?

Yes, they absolutely can. But it all comes down to proper engineering. To handle heavy or abrasive materials vertically, the conveyor needs the right screw geometry, extra wear protection and heavy-duty parts to manage the friction. When built specifically for those tough conditions, they do the job beautifully.

Can Cosben customize conveying and feeding systems for my plant layout?

Yes. As an OEM, Cosben designs customized screw conveyor and feeder systems based on plant layout, material behaviour, capacity requirements and integration with existing equipment.

What industries commonly use Cosben's conveying and feeding equipment?

Our systems are widely used across a variety of sectors, including cement, RMC, food processing, flour milling, animal feed, chemicals, minerals, plastics, foundry and glass industries.

Do you provide installation, commissioning and after-sales service?

Yes, we do. Cosben provides full installation, commissioning, maintenance and OEM service support to ensure your equipment operates reliably and lasts for years to come.

How do screw conveyor systems improve plant efficiency?

They take care of the heavy lifting by reducing manual handling, improving flow consistency and minimizing spillage and dust. By supporting automation, they help you achieve better safety, higher productivity and lower operating costs.

Can existing plants retrofit Cosben conveying and feeding systems?

Absolutely. We regularly work on retrofit and modernization projects, smoothly integrating new conveying and feeding systems into existing plants with minimal disruption to your daily operations.

What information is required to select the right system?

To get the perfect fit, we look at material properties, bulk density, moisture content, your required capacity and plant layout. Knowing your operating hours and integration requirements also helps us engineer the right solution.

Why choose an OEM instead of a trader or standard supplier?

When you partner with an OEM like Cosben, you get proper engineering, seamless system integration, genuine spares and long-term service support. With clear accountability from the manufacturer, you benefit from lower lifecycle costs and far more dependable performance.
