Every piece of equipment starts as an application drawing, engineered around your material and process before a single part is fabricated.
Industries We Serve
No two industries handle bulk materials in the same way. A cement plant moves highly abrasive powders, while a food processing facility prioritises hygiene and contamination control. Plastic processing often involves free-flowing granules, whereas chemicals, minerals and specialty powders can present their own flow challenges depending on their physical properties.
At Cosben Engineering, we don’t believe in one-size-fits-all equipment. Every solution is developed around the way your material behaves, your production requirements and your operating environment.
Industries We Serve
Supporting manufacturers involved in cement, premixed building materials, ready-mix concrete, fly ash, lime, asphalt and other construction materials where reliable conveying, feeding, storage and discharge are essential for continuous production.
Process Industries
Engineered equipment for handling powders used in chemical processing, mineral processing, pharmaceutical manufacturing, food production, flour milling and animal feed applications where controlled material movement directly influences production consistency.
Manufacturing Industries
Reliable bulk material handling equipment for industries processing ceramics, foundry materials, glass raw materials, plastics and specialty manufacturing powders.
Every Industry Has Different Material Flow Challenges
Although the equipment may look similar, the application rarely is. Understanding these differences helps ensure equipment is selected according to the application rather than simply matching capacity requirements.
- 01 Fine powders may require controlled feeding to maintain consistent material flow.
- 02 Abrasive materials demand equipment designed for long service life.
- 03 Hygienic applications require equipment that supports easier cleaning and contamination control.
- 04 Cohesive powders often need carefully selected discharge equipment and flow aids to improve material movement.
- 05 Granular materials may require different conveying and feeding approaches than fine powders.
"That's why every recommendation from Cosben begins with understanding the material, not just the process."

Engineering the Way Materials Move
Every manufacturing plant depends on one thing: materials moving reliably from one process to the next. When materials stop flowing consistently, production slows, downtime increases and maintaining product quality becomes more challenging. At Cosben Engineering, we design and manufacture industrial bulk powder handling solutions that help industries convey, feed, store, discharge and control bulk materials with confidence.
As an industrial material handling systems manufacturer and bulk handling equipment manufacturer in India, we engineer equipment around your material characteristics, production requirements and plant layout, not just equipment capacity. Whether you’re expanding an existing production line or installing new bulk material handling equipment, our application engineers work closely with your team to recommend practical, reliable solutions that support long-term plant performance.
No two bulk materials behave the same. Some powders bridge inside storage hoppers, others generate dust during transfer, while abrasive materials can accelerate equipment wear. Designing reliable bulk material handling systems begins with understanding these material characteristics before selecting the equipment.
At Cosben Engineering, every project starts with the application. Our engineers evaluate material properties, production capacity, conveying requirements, plant layout and operating conditions to recommend industrial process material handling solutions that integrate seamlessly with your existing production equipment. From individual machines to turnkey bulk material transfer solutions for material handling equipment packages, our focus remains the same: helping manufacturers improve material flow through dependable engineering and well-designed equipment.
Every production facility has different material flow challenges. Some plants struggle with inconsistent feeding, while others face material build-up inside hoppers, dust generation at transfer points or unreliable discharge from storage silos. Simply replacing one piece of equipment rarely solves these issues, so we develop bulk solids handling solutions for industries by understanding how your materials move through the entire production process. Our application engineers evaluate material characteristics, production requirements, plant layout and operating conditions to recommend customized powder handling equipment that supports reliable material flow and long-term plant performance, whether you're installing a new line or upgrading an existing one.

Plant efficiency, how a powder actually behaves and what an in-house engineering team changes about the result, written by the people who specify and build the equipment.
Manufacturing Excellence, Built on Engineering Precision
Good equipment starts with a good process. Every machine we build goes through the same steps: careful design, controlled fabrication and quality checks at every stage, not just at the end. Each month, Cosben manufactures 400+ screw feeders and conveyors for customers across a wide range of process industries. That scale, combined with hands-on engineering support, means we can handle anything from a single machine to a full equipment package.
Before any equipment leaves our facility, it goes through a final inspection to check quality, assembly and dispatch readiness. Our goal is simple: your equipment should work reliably from day one. That means less downtime, steadier production and fewer maintenance headaches down the line. That’s why our manufacturing philosophy is built around engineering precision, quality workmanship and continuous aftersales support, not shortcuts.
Robotic Profile Cutting
Accurate profile cutting helps maintain dimensional consistency, improves fitment during fabrication and supports repeatable manufacturing quality across every production batch.
Precision Welding
Strong fabrication begins with precision welding. Our manufacturing process focuses on weld quality, structural integrity and consistent workmanship for long service life in demanding applications.
Fabrication & Finishing
Grinding, deburring and surface finishing bring every fabricated component to its final tolerance and appearance before it moves on to assembly.
Multi-Stage Quality Inspection
Quality isn’t verified at the end of production, it’s monitored throughout. Each stage undergoes systematic checks for dimensional accuracy, fabrication quality and component fitment.
Frequently Asked Questions
Straight answers to the questions manufacturers and EPC contractors most often ask us before starting a project.
What is the difference between a screw conveyor and a screw feeder?
A screw conveyor moves bulk material from one point to another over a set distance, while a screw feeder meters material out of a hopper or silo at a controlled, consistent rate. Cosben manufactures both, often supplying combination units where conveying and metering happen in a single machine.
Does Cosben manufacture custom bulk material handling equipment?
Yes. Every Cosben project starts with your application: our engineers evaluate material characteristics, production capacity and plant layout before recommending equipment, so specifications are built around your process rather than adapted from a generic catalogue model.
