Clean, Safe, Dust-Free Powder Removal and Transfer from Bag, Sacks, Drums, Barrels, Containers, Bins
Modern manufacturing industries require safe, hygienic and dust-free powder handling.
Manual powder transfer from bags or drums often leads to:
- Dust emission
- Material loss
- Operator exposure
- Contamination
- Poor productivity
Vacuum conveying systems automate the process by removing powders directly from bags, sacks, drums or containers and transferring them through enclosed pipelines to the next process step.
Typical Powder Transfer Process
Step 1 – Powder Source
Powder is stored in:
- Bags / sacks (25–50 kg)
- Fibre drums
- Fibre drums
- Big bags (FIBC)
- Containers or bins
Step 2 – Controlled Discharge
Powder is introduced into a bag dump station or drum unloading station equipped with:
- Dust extraction
- Vibrating screen
- Lump breaker (optional)
Step 3 – Vacuum Conveying
The system creates vacuum using compressed air ejectors or vacuum pumps and draws powder through pipelines into a receiver hopper.
Step 4 – Discharge to Process
Material is discharged into:
- Mixers
- Reactors
- Blenders
- Tablet presses
- Filling machines
- Storage bins
Key Features
Material is discharged into:
Powder travels in sealed pipelines, eliminating dust and contamination.
Safe Handling of Hazardous Powders
Operators are not exposed to fine dust or toxic powders.
Hygienic Stainless Steel Construction
Systems can be designed in SS304 or SS316 for food, pharma, and chemical industries.
Gentle Material Handling
Dense-phase conveying protects fragile materials from degradation.
Modular and Flexible Design
Systems can be integrated easily into existing production lines.
High Transfer Capacity
Typical conveying rates up to 15 tons/hour depending on material.
