BULKER – Pneumatic conveying

Pneumatic conveying is defined as the transfer of solid materials in granular or powder enclosed in the drive pipe with a fluid, usually compressed air. There are different classifications for pneumatic conveying, in the first one takes into account the ratio between the fluid and solid transport, hence dense phase and dilute phase. The second discriminates between positive pressure systems (supply) or negative pressure systems (aspiration).

Dense phase

Is a dense phase pneumatic conveying type is characterized by the high proportion of output with respect to air. The conveying speed is low, preventing degradation, segregation of particles. This type of convey is also highly recommended for abrasive wear as the pipe is much lower than in the dilute phase. The 300T/ha productions can reach distances over 500 meters.

Key Benefits

  • Closed system with no loss of material, or emissions to the atmosphere.
  • Enables convey over long distances and high production capacities.
  • Gentle product handling to avoid breakage of particles.
  • Minimal wear on equipment, dramatically reducing maintenance.
  • Low power consumption compared to other transport technologies.
  • Fast return on investment.

Diluite phase

The dilute phase pneumatic conveying is one which the particles move through pipes at high speed with a lot of air at low pressure. It comes in two forms preseure and suction. Drive systems are effective to feed several points from the point of shipment, while exhaust systems are advantageous when we need to nurture an item from different points.

  •  Conveying capacity from 0 to 50 T / h.
  •  Conveying speeds generally between 15 – 30m / s.
  •  Conveying distances up to 200 m.
