The Lean Phase Pneumatic Conveying System by KI CONEQUIP is an advanced bulk material handling solution designed for transporting powders and granules at high velocity using low-pressure air. Ideal for lightweight, non-abrasive, and free-flowing materials, this system ensures continuous conveying with minimal material degradation and high conveying efficiency.
Built with blowers, rotary airlock feeders, pipelines, filters, and automated control systems, the KI CONEQUIP Lean Phase Conveying System enables smooth and dust-free material transfer over long distances. Widely used in plastics, food processing, chemicals, pharmaceuticals, flour mills, and packaging industries, it enhances production efficiency, reduces manual handling, and maintains a clean and safe working environment.
Request A QuoteLean 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.
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.
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.
As a reputed pneumatic conveying system manufacturer in Gujarat, KI CONEQUIP delivers end-to-end solutions—from audit and sizing to commissioning and after-sales. Our design team optimizes pipeline routing, blower power, and filtration to ensure stable flow with low operating cost.
We offer standard modules as well as custom builds to suit your material, throughput, and layout constraints. Fast response, spares availability, and remote/onsite support make us a dependable partner for powder handling.
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.
Yes. We can integrate diverter valves and sequence control to feed multiple receivers or process points, with interlocks for safe operation.
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.
Absolutely. We offer food-grade contact parts, FDA-compliant elastomers, and ATEX-oriented safety provisions (vents/isolators) based on risk assessment and local regulations.
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.
