Product Overview
Pneumatic Conveying That Adapts to Your Material Profile
TNBi’s Pneumatic Conveying Systems transfer powders, granules, and abrasives through sealed pipelines using air or inert gas. Depending on the system design, material is conveyed using either positive pressure or vacuum. Based on parameters like material characteristics, gas velocity, and pressure, systems are generally classified as Lean Phase or Dense Phase pneumatic conveying. Both in Vacuum and Pressure.
Product USP

Reliable & Precise
Consistent performance
Customized solution
Pressure and vacuum-based options for layout flexibility and application
Clean, Safe & Energy Efficient
Fully enclosed operation
Lower maintenance and optimize power consumption
Compatible with inert gas for hazardous materials
Designed for Versatility
Lean and dense phase variants
Multiple Suction/discharge points are possible
Supports abrasive, corrosive, and combustible materials
Installation Layout
Use Cases
Applications Across Bulk Solids and Fine Powder Conveying
Pharma Powder Transfer
Conveys APIs and other powders in a hygienic, closed-loop system.
Dust-Free Transfer in Hazard Zones
Ideal for combustible, toxic, or corrosive materials using inert gas loops.
Blending Line Feeding
Feeds ingredients to mixers, blenders, or reactors with accurate flow control.
Bulker Unloading Systems
Discharges materials like fly ash, sugar, or chemicals from tankers into storage.
Mill Outlet Conveying
Transfers powder from grinders or mills to silos or downstream processes.
Central Vacuum Collection
Collects material from multiple suction points across processing lines.
Challenges vs TNBi's Solutions
How Do We Eliminate Choking, Fires, and Filter Breakdowns?
“Dust escapes into the plant environment”
Enclosed, leak-proof pipelines ensure a dust-free transfer
“Conveying damaged, fragile materials”
Low-velocity dense phase is designed for gentle material handling
“System gets clogged or overloaded”
Configured based on material flow, density, and phase logic
Case Studies
Proven in the Field
High-Efficiency Cyclone Replaces Fire-Prone Bag Filter
Challenge: A A A polymer processing facility handling ultra-fine powder after milling faced major operational setbacks due to an overloaded bag filter system. With dust loading at 8750 mg/Nm³ and over 90% of particles smaller than 9.1 µm, the existing setup couldn’t manage the fine particulate burden. This led to frequent fires, 18-hour downtimes, and repeated filter bag failures under heat and pressure.
TNBi Solution: To replace the breakdown-prone filter system, TNBi deployed a cyclone separator designed for high dust loads, eliminating the need for filter bags. The system featured a no-moving-parts design, which prevents choking, reduces maintenance, and ensures safe, spark-free operation. Its compact configuration also minimized noise and simplified integration into the plant’s layout.
Result
- Emission level brought down to <25 mg/Nm³ >
- 99.72% collection efficiency achieved
- Zero fire incidents
- Higher product recovery and uptime

FAQ's
Frequently Asked Questions
What is a pneumatic conveying system, and how does it work?
A pneumatic conveying system transfers dry materials like powders and granules through pipelines using air or inert gas. It can be pressure- or vacuum-driven, ensuring dust-free, enclosed transfer from source to destination.
What's the difference between the lean phase and dense phase conveying?
The lean phase conveying uses high-speed, low-pressure air to suspend and move lighter materials. Whereas the dense phase conveying system utilizes low-speed, high-pressure airflow to push heavier or abrasive materials in slugs, thereby reducing material degradation.
Can TNBi pneumatic systems be customized to my layout and process?
Yes. TNBi offers a system that’s custom-engineered to your material type, flow rate, conveying distance, space constraints, and safety requirements (including inert gas loops for hazardous zones).
