Dense phase Conveying Systems

Dense Phase Conveying Systems

In dense phase conveying systems, a variety of dry bulk materials including powders, pellets, granules, and flakes are efficiently transported through a sealed pipeline. This method utilizes compressed air to propel materials at high pressure and low velocity from a pressure vessel, traversing the pipeline to reach single or multiple destination points (feeding points). Upon arrival, the product and air are separated via a filter. Typically, abrasive, friable, or blended materials necessitate the use of a dense phase system, ensuring gentle handling throughout the delivery process.

As a leading pneumatic conveying system manufacturer, Rajdeep employs cutting-edge technology to craft top-tier dense phase conveying systems. Whether you require a comprehensive solution for bulk material handling or individual equipment components, our expertise covers all aspects. Moreover, our services extend beyond mere equipment provision; we offer comprehensive support including field service, start-up assistance, thorough material testing, and reliable spare parts supply for dense phase pneumatic conveying systems.

Salient Features:

  • Use High pressure, Low volume gas & Low velocity to transfer powder or granular bulk solids.
  • Specially designed Pressure vessels with valves & air control are the key components of the system
  • Solid-to-air ratio ( Kg solid / Kg air) should be more than 10
  • For a Dense phase pressure system conveying length can be more than 1000 meters
  • These systems use Compressed Air / Gas to develop the required motive force.
  • Dense phase systems are most used on that material which is Abrasive, Fragile, High-density
  • Dust-Free Operation

Dense Phase Pneumatic Conveying Systems - Key Features

  • Dense phase conveying systems occurs when materials are conveyed with air velocities lower than those required for dilute phase over all or part of the pipeline.

  • Dense phase conveying systems is often referred to as non-suspension flow. In which the material is conveyed as the full bore plugs separated by air gaps.

  • The dense Phase conveying systems is characterized by Low velocity, High pressure & High solid-to-air ratio.

The Dense Phase Conveyor stands out as a user-friendly conveying system, boasting minimal maintenance requirements and a low installation cost. It proves particularly well-suited for applications where materials need to be transported over extensive distances and delivered to multiple feeding points with high capacity.

Operating at low velocities, the dense phase pneumatic conveyor offers the added advantage of prolonging system lifespan, particularly when handling abrasive materials. Its low conveying velocities within the pipeline contribute to reduced wear and tear, thereby minimizing the risk of breakdowns.

Furthermore, its closed-loop design effectively eliminates dust, eliminating the need for robust dust collection systems. Compared to mechanical transfer methods, dense phase conveying systems offer the flexibility to navigate more complex routes while ensuring a dust-free transfer process.
