What is a Powder Transfer System?

What is a Powder Transfer System? – A powder transfer system moves powders or granules from one point to another in a closed pipeline using air or vacuum pressure, instead of manual handling.

Commonly used in:
Pharma • Chemicals • Food • Minerals • Battery materials • APIs

⚙️ Basic Working Principle – What is a Powder Transfer System?

1️⃣ Feeding Stage

Powder is loaded into the system from:

• Bag dumping station
• Big bag unloading station
• Hopper
• Silo
• Reactor discharge

2️⃣ Conveying Stage (Air / Vacuum Flow) 

Depending on the design, either:

🟦 Vacuum Conveying

A vacuum pump creates negative pressure in the pipeline.
Atmospheric air pulls the powder into the pipeline and transports it to the destination.

OR

🟥 Pressure Conveying

A blower / compressor pushes air into the pipeline and pushes powder forward.

Powder moves as:

• Dilute phase → fast-moving powder cloud
• Dense phase → slow, plug-type movement

3️⃣ Transport Through Pipeline

Inside the pipeline:

• Powder particles are suspended or pushed by air
• Flow rate, pressure, and velocity are carefully controlled
• No contamination, no spillage

4️⃣ Separation at Receiving End

At destination (reactor, blender, dryer, silo):

• Cyclone / Filter receiver separates powder from air
• Clean air goes out through filters
• Powder drops into the process vessel

5️⃣ Discharge & Next Operation

Collected powder is discharged through:

• Rotary valve
• Butterfly valve
• Knife gate valve
  Into the next machine: reactor, ANFD, FBD, blender, etc.

🧪 Example in Pharma Plant

From: Bag dumping station
→ Powder transfer system
→ Reactor / ANFD / Blender

All in a closed, dust-free, GMP-compliant loop.
