Vacuum Conveying System for Automated Reactor Feeding
Project Background
A chemical manufacturing company in Kazakhstan required a reliable solution for feeding multiple powder materials (additives, fillers, and other raw materials) into reactors. Their existing manual process presented several challenges:
- ❌ Severe dust emissions – poor workshop environment affecting worker health and safety
- ❌ Low feeding efficiency – high labor intensity and slow batch turnover
- ❌ Inaccurate dosing – recipe errors leading to inconsistent product quality
- ❌ Safety risks – manual handling at height and exposure to chemicals
To overcome these challenges, the client decided to implement an automated vacuum conveying system for closed, metered reactor feeding.
Customized Solution
Guanjiang designed and supplied a complete vacuum conveying system tailored to the client's reactor feeding process, consisting of the following integrated components:
Manual bag opening with integrated dust collection — eliminates dust emissions at the source during powder unloading.
Closed-loop negative pressure system transfers powder through pipelines directly to the reactor inlet — fully contained.
Material enters a buffer hopper with load cells for precise batching before discharging into the reactor.
Fully automated control integrated with the reactor's process logic — enables batch scheduling, automatic changeover, and remote monitoring.

Operator Can Serve
Multiple Reactors
- Environmental & Safety: Dust emissions virtually eliminated; workshop environment significantly improved; reduced manual exposure to chemicals.
- Efficiency: Average feeding time reduced by 40%; production rhythm more consistent and reliable.
- Quality: Accurate batching with minimal deviation — product consistency and quality greatly enhanced.
- Labor: One operator can now manage feeding for multiple reactors, reducing labor costs significantly.
“The vacuum conveying system has transformed our reactor feeding process. Feeding is now fully enclosed and automated — we've achieved better production environment, improved product quality, and higher efficiency. We plan to roll out similar systems to other workshops in our facility.”
