For low- or high-rate transfer of abrasive or friable material, dense phase conveying is the optimum solution.

For low- or high-rate transfer of abrasive or friable material, dense phase conveying is the best choice. Dense phase pneumatic conveying is a relatively low-speed system where the material is not suspended in the air stream. The low velocity of dense phase means less wear and tear on both the system and the materials being conveyed.

Our pneumatic conveying experts can ascertain the correct conveyance phase for your material in order to design a custom system that successfully meets your unique material handling requirements. We offer models with vacuum or gravity load, featuring top or bottom discharge to match your application and materials.

Dense Phase is Ideal with:

  • Very fragile materials and mixtures, as the low speed and lower air volumes prevent materials from breaking down.
  • Best for low- or high-rate transfer of abrasive or friable materials, as the slow convey speed reduces abrasion of convey lines.
  • Slightly hygroscopic materials, without requiring the introduction of air drying equipment because air quantities required for dense phase are significantly lower than that of semi-dense and dilute.
