- Brand： glzon
- Model： GZM
Product Essence: Engineering Precision in Every Particle
Shanghai Guangzhi Powder Conveying Systems deliver 10 tons/hour transfer rates with <0.01% residual powder – mastering micron-scale APIs, explosive dusts, and hygroscopic powders via pressure-dilute phase technology, AI flow stabilization, and ATEX Zone 20/22 certification. Featuring 316L electropolished surfaces (Ra≤0.4μm), nitrogen inerting, and CIP/SIP readiness, they eliminate cross-contamination, dust explosions, and product degradation in pharmaceutical, food, and chemical operations.
