Powder Conveying: Efficient & Hygienic Transfer of Bulk Powders
Powder conveying is a critical process in industries that handle dry, bulk powdered materials such as plastics, chemicals, food processing, pharmaceuticals, and minerals. An efficient conveying system ensures reliable transfer of powders with minimal loss, no dusting, and consistent flow all while maintaining product integrity.
At Margo Industries, we specialize in designing and manufacturing high-performance powder conveying systems customized to your material properties, plant layout, and production goals. Whether you’re handling fine, cohesive powders or free-flowing materials, our solutions are engineered for accuracy, hygiene, and efficiency.
What is Powder Conveying?
Powder conveying refers to the controlled movement of powdered materials from one processing point to another such as from a silo to a mixer, a bag dump station to a hopper, or a storage bin to a packaging line. These systems are typically powered by air (pneumatic conveying), which can be done using either positive pressure or vacuum.
Depending on the characteristics of the powder (bulk density, flowability, abrasiveness, hygroscopic nature), different conveying technologies are used, including:
- Lean Phase Conveying – For light, free-flowing powders
- Dense Phase Conveying – For abrasive, fragile, or heavy powders
- Vacuum Conveying – For hygienic and dust-free transfer
- Mechanical Conveying (optional) – For specific short-distance applications
Margo Industries provides complete, turnkey powder conveying solutions using pneumatic methods, offering superior control, cleanliness, and automation.
Materials We Handle
Our systems are optimized for a wide range of powder types, including:
- Flour, starch, sugar, cocoa powder, milk powder
- PVC powder, resins, pigments, and color masterbatch
- Cement, silica, fly ash, lime, calcium carbonate
- Detergents, fertilizers, talc, and chemicals
- APIs, excipients, and other pharma-grade powders
We perform flowability analysis and test runs to ensure each system is built for your specific material.

Why Pneumatic Conveying is Ideal for Powders
Pneumatic conveying is the most efficient and hygienic method for transporting powders in bulk. Here’s why it’s the preferred choice:
- Dust-free operation – Eliminates spillage and airborne particles
- Safe and enclosed system – Suitable for explosive or toxic powders
- Low maintenance – No mechanical belts or chains
- Flexible layout – Can be routed over long distances and around obstacles
- Automated control – Integrates easily with SCADA/PLC systems
- Sanitary handling – Especially important in food and pharma sectors
Depending on your application, we help you choose between lean phase, dense phase, or vacuum-based powder conveying — ensuring the system matches your exact needs.
