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.
