Packaging Solution for Acid Dye Ultra-Fine Powder in the Dye & Chemical Industry
Customer Pain Points
Acid dye powder has an ultra-fine particle size of 0.5–8 μm. Traditional packaging equipment suffered from poor sealing performance, leading to severe dust leakage and a workshop dust concentration of up to 28 mg/m³.
This not only caused cross-contamination between dye batches, reducing product purity by 18%, but also resulted in failure to meet environmental compliance standards, preventing entry into the European market.
Additionally, manual sealing generated significant airborne dust, posing serious occupational health risks to workers.
Dust Control & Technical Solution
The Henll fully automatic big bag packaging system was implemented with the following key features:
- Enclosed feeding system using a flexible telescopic sleeve combined with a pneumatic butterfly valve, ensuring airtight material transfer
- Negative pressure isolation hood in the packaging area, maintaining a micro-negative pressure of -50 Pa to prevent dust escape
- Pulse-jet bag filter system with a filtration accuracy of 0.3 μm, effectively capturing ultra-fine particles
- Integrated 120-mesh vibrating screen at the feeding inlet for pre-dust removal
- High-pressure air cleaning system to remove residual dust from the bag surface after sealing
- Dust concentration sensors installed for real-time monitoring, with automatic shutdown and alarm when limits are exceeded
Results & Benefits
- Workshop dust concentration reduced to 3.2 mg/m³, meeting EU REACH environmental standards and enabling successful entry into the European market
- Cross-contamination completely eliminated, with product purity compliance improved to 99.8%
- Zero employee health complaints, significantly improving workplace safety
- Dust recovery rate reached 99.5%, saving over RMB 600,000 annually in raw material costs
