Unused Atex Graphite Dense Phase Conveying & Blending System

3,000 KG Batch – 500 KG/H – Explosion Rated – Stainless Steel – PED Certified

Unused, engineered dense phase pneumatic conveying and blending system originally designed for ultra-fine graphite powder in a classified explosion safety zone.

This is not a general-purpose powder system. It was custom-engineered for:

Fine particle size (5–50 µm)
Low bulk density material (0.34–0.58 kg/dm³)
Ultra-low moisture (<0.1%)
Explosion-risk environment
Controlled dense-phase transfer
Pressure-assisted blending

Original new cost: $389,088 CAD

System has never been commissioned.

Designed specifically for:
• Graphite
• Carbon black
• Battery materials
• Fine minerals
• Conductive powders
• Explosion-sensitive dust
Ideal for operations requiring:
✔ Dense phase conveying
✔ Controlled low-velocity transport
✔ Dust cloud minimization
✔ ATEX / explosion safety compliance
✔ Homogeneous batch blending
