Challenges vs TNBi's Solutions
How It Solves the Consistency Issue in Classification?
“Our classifier blades wear out too fast”
No moving parts, zero wear, no replacement parts needed
“Separation drops in humid/rainy weather”
Secondary air fine-tuning maintains cut size even in monsoon
“Too much downtime due to filter choking”
Low-choke design prevents load on bag filters
Case Studies
Proven in the Field
Fly Ash Classification in Beed, Maharashtra
Challenge: Low recovery (40–52%), bag filter clogging, rain-related output drop, and high wear.
TNBi Solution: Two-stage classifier with closed-loop air, bag filter integration, and ultra-fine tuning
Result

FAQ's
Frequently Asked Questions
What is a classifier without rotating parts, and how does it work?
A classifier without rotating parts separates fine and coarse powder by using aerodynamic modelling instead of mechanical rotors. The airflow naturally creates a motion, generating separation force.
What are the advantages of a classifier without moving parts?
A classifier without moving parts (like TNBi’s classifier) offers Less wear and tear, no spare parts, and minimal maintenance. This makes it ideal for industries handling abrasive, sticky, or combustible powders, thereby reducing downtime, choking issues, and operating costs.
Can a TNBi classifier be integrated into an existing powder processing line?
Yes. TNBi’s classifier is designed for easy in-line installation with mills, grinders, cyclones, or bag filters. It supports both retrofits and new setups, enabling seamless integration into your process flow without major layout changes.
