Pneumatic pellet and flake conveying

For the customer POLYMETRIX process technology always means a comprehensive solution from one supplier. We offer optimized system solutions free of interfaces from receipt of the raw material through to storage and processing. 

Our process technologies are usually combined with the proprietary POLYMETRIX pellet and flake conveying systems. We supply both dilute phase and dense phase transport technologies. The dense phase transport technology is often preferred in order to transport the product without damage and minimal dust generation.


  • Capacities up to 2000 t/d
  • Dense phase technology at low velocity to avoid dust generation
  • Dilute phase conveying technology at high velocity and low pressure to reduce conveying costs
  • Open loop air systems
  • Closed loop nitrogen systems
  • Closed loop nitrogen systems with integrated gas purification
