Powder Transfer System – Process Flow Explanation
Step 1 – Raw Material Feeding
Powder is charged into the system from:
-
Bags / sacks
-
Drums / big bags
-
IBCs / silos
This is done through:
-
Bag Emptying Station
-
Feed Hopper
-
Vacuum Loading Point
Dust extraction ensures clean & safe feeding.
Step 2 – Conveying Generation
A vacuum pump or roots blower creates the required conveying force.
Depending on application:
-
Vacuum → pulls powder
-
Pressure → pushes powder
This energy source controls the material flow velocity and conveying capacity.
Step 3 – Material Transport Through Pipeline
The powder moves through a closed stainless-steel pipeline.
Transport modes:
-
Dense Phase – slow, gentle, low degradation
-
Dilute Phase – fast, high throughput
The pipeline is designed with:
-
Minimal bends
-
Smooth interiors
-
Optimized diameter
This prevents product breakage and pipeline choking.
Step 4 – Air–Material Separation
At the destination, the mixture enters a Receiving Hopper / Cyclone Separator.
Here:
-
Powder drops by gravity
-
Air passes through cartridge filters
-
Clean air exits to atmosphere
Automatic pulse jet cleaning maintains filter efficiency.
Step 5 – Product Discharge to Process Equipment
The separated powder is discharged into:
-
Reactor
-
Blender
-
Dryer (FBD, RVD, VTD, ANFD)
-
Storage hopper
-
Packing machine
Discharge devices used:
-
Rotary airlock valve
-
Butterfly valve
-
Double flap valve
Step 6 – Control & Automation
The entire process is controlled through a PLC-based control panel:
Controls:
-
Conveying sequence
-
Filter cleaning
-
Level sensors
-
Interlocks & safety
This ensures fully automatic, repeatable and safe operation.
