Dilute phase pneumatic conveying systems move dry bulk solids such as powders, granules, and pellets through a pipeline using a high-velocity air stream. This technology suits applications with moderate flow rates and short distances, offering a cost-effective and versatile solution for processing plants.

The system uses continuous air flow from a blower or compressor. The air stream exceeds the saltation speed of the material, suspending particles and carrying them along the line. A pressure difference drives the flow while the solids concentration stays low, maintaining the dilute phase state.

Typical components include an air supply unit, a rotary airlock or venturi feeder, conveying pipe, cyclone separator, and dust collector. The blower provides required air volume and pressure. The feeder introduces bulk material into the pipeline. The pipe, made of carbon steel or stainless steel, connects the feed point to the receiving hopper, where the separator and collector remove the material from the air.

Systems are available as pressure type or vacuum type. In pressure conveying, the blower sits upstream and pushes material over longer distances to multiple discharge points. In vacuum conveying, the blower is at the line end, pulling material from multiple sources into one destination. This is ideal for unloading vessels or feeding hoppers.

The main advantages are simplicity and low capital cost compared to dense phase systems. Piping can be routed overhead, underground, or around equipment with minimal structural modifications. No moving parts inside the pipeline means low maintenance and reliable operation. The closed design prevents contamination and reduces dust emissions, ensuring a cleaner and safer workplace.

Dilute phase conveying is widely used in food, chemical, pharmaceutical, and building material industries. It handles flour, sugar, starch, plastic pellets, additives, cement, fly ash, and similar dry solids. Other uses include mineral processing, agriculture, and waste handling, where bulk materials move from storage to processing or packaging equipment.

As a manufacturer of dilute phase conveying systems, we offer custom-engineered solutions based on your material properties and process needs. We determine the correct conveying velocity, pipe diameter, air flow, and power consumption through calculation and testing. Our team designs an efficient layout and selects components that integrate smoothly with your existing line, lowering operating costs.

The price of a dilute phase system depends on conveying distance, capacity, material bulk density and abrasiveness, and automation level. Additional factors include build materials, explosion-proof requirements, and special features such as inert gas conveying or vacuum unloading. We offer transparent, competitive pricing with detailed quotes tailored to your project specifications.
