Description

What is a Lean Phase Pneumatic Conveying System?

Lean phase (also called dilute phase) conveying transports bulk solids suspended in a high-velocity airstream at relatively low pressure and low solids loading. It is versatile, economical, and suitable for long conveying distances with multiple pickup and discharge points. Typical applications include silo filling, batching, process feeding, and inter-process transfer in cement, food, chemical, plastic, and mineral industries.

How Lean Phase Conveying Works

A positive displacement blower or high-capacity fan generates conveying air. Material is introduced into the pipeline via a rotary airlock valve, venturi eductor, or suction pickup. The product remains fully suspended as it travels through bends and horizontals at velocities typically in the range of 18–28 m/s (medium-fine powders) depending on particle size and fragility. At the destination, a receiver with filters separates material from air; cleaned air is vented via a bag filter or cartridge filter, while product is discharged to storage, a process vessel, or a weighing/batching hopper.

Key Features of KI CONEQUIP Lean Phase Systems

  • Integrated instrumentation: DP switches, MPA/Pa gauges, airflow monitoring.
  • Food-grade and ATEX-compliant designs available on request.
  • Compact footprint with easy access for maintenance.
Benefits for Your Plant
  • Clean, enclosed conveying with minimal spillage and dust.
  • Flexible routing over long distances and multiple elevations.
  • Gentle handling for many powders and granules with low product loss.
  • Fast conveying suitable for continuous or batch duty.
  • Lower capital cost than dense phase for many applications.
  • Easy integration with silos, weigh batching, mixers, and packaging lines.

Typical Materials Handled

Cement, fly ash, lime, alumina, silica, flour, starch, sugar, salt, spices, PVC/PE/PP regrind, masterbatch, talc, gypsum, bentonite, soda ash, detergents, and similar free-flowing powders/granules.

System Options & Components

  • Air Movers: Twin-lobe/tri-lobe blowers, high-capacity fans (positive pressure or vacuum).
  • Feeding: Rotary airlock valves, venturi/eductor, suction wands, hopper pickups.
  • Pipeline: MS/SS, food-grade, wear-resistant bends; quick-release couplings (optional).
  • Receivers: Cyclone + bag/cartridge filter with pulse-jet cleaning and rotary valve discharge.
  • Controls: PLC/SCADA integration, interlocks, soft-start/VFD for blower, alarm stack.
  • Hygiene & Safety: CIP-friendly layouts, explosion vents/isolators where required.

Application Ranges (Typical)

  • Capacity: ~1 – 40 TPH (product dependent).
  • Distance: Up to 300 m horizontal equivalent with multiple bends.
  • Air–to–Solids Ratio: Typically 5:1 to 12:1 (by mass), adjusted per product/line.
  • Velocity: 18–28 m/s for powders; tuned to minimize attrition and line wear.

FAQs

When should I choose lean phase over dense phase?

Choose lean phase for general-purpose, continuous conveying of free-flowing powders/granules where higher velocities are acceptable and capital cost needs to be economical. Dense phase is preferred for very fragile, abrasive, or high-bulk-density products requiring lower velocity and ultra-low degradation.

Can one system feed multiple destinations?

Yes. We can integrate diverter valves and sequence control to feed multiple receivers or process points, with interlocks for safe operation.

What about dust control and filtration?

Receivers use bag or cartridge filters with pulse-jet cleaning to separate product from air and keep emissions low. Optional cyclones and secondary filters can be added for fine powders.

Do you supply food-grade/ATEX compliant systems?

Absolutely. We offer food-grade contact parts, FDA-compliant elastomers, and ATEX-oriented safety provisions (vents/isolators) based on risk assessment and local regulations.

What inputs do you need to size my system?

Material name and bulk density, particle size, moisture, abrasiveness, source/destination elevations, pipeline route (lengths & bends), required throughput (TPH), and available utilities help us design the optimal solution.
