In the battlefield of industrial material transportation, pneumatic conveying system has become a powerful assistant for many companies to improve production efficiency with its unique charm. Faced with two major schools of thought - dense phase pneumatic conveying system and dilute phase pneumatic conveying system, how to make a wise choice has become a key issue for engineers and decision makers. The following is our comprehensive analysis of these two systems to help you find the most suitable conveying solution for industrial applications.

 

Dense phase pneumatic conveying system: a synonym for precision and stability

Dense phase pneumatic conveying system, with its low speed and high pressure characteristics, has become the first choice for the transportation of fragile and abrasive materials. The following are its core advantages and application details:

· The ultimate pursuit of material protection: The low-speed characteristics of dense phase conveying make the material as if it is gently cared for during the conveying process, greatly reducing material damage, especially suitable for sensitive materials such as food and medicine.

· Extension of equipment life: Due to the slow material flow rate, pipeline wear is greatly reduced, the service life of the equipment can be extended, and maintenance costs are saved for the company.

· Pioneer of energy saving and environmental protection: Although the initial pressure is high, the overall energy consumption is low, which meets the requirements of green production.
A model of closed conveying: The completely closed conveying process effectively prevents material leakage and environmental pollution, and improves the cleanliness of the production workshop.

·  Applicable scenarios: The dense phase pneumatic conveying system is suitable for use in short-distance, high-pressure, and low-speed environments, especially when it is necessary to handle high-density, brittle or abrasive materials. Typical application scenarios include: the transportation of powdered or granular materials in food processing, pharmaceuticals, and chemical industries, such as flour, sugar, pharmaceutical powder, chemical raw materials, etc.

Dilute phase pneumatic conveying system: a model of speed and efficiency

The dilute phase pneumatic conveying system, with its high-speed and low-pressure conveying method, has a place in the field of large-volume material conveying. The following are its highlights and practical applications:

· Quick-response production line: High-speed conveying capacity allows materials to reach their destination quickly, improving the response speed of the production line.

· Simple and economical system design: Compared with the dense phase system, the dilute phase system is simpler in design, reduces investment costs, and is easy to maintain.

· Widely compatible material handling: Whether it is plastic granules or grains, the dilute phase system can easily cope with it, and its adaptability is evident.

· Expert in long-distance transportation: For materials that need to be transported over long distances, the dilute phase system performs well and effectively reduces the intermediate links.

· Applicable scenarios: In grain processing plants, the dilute phase pneumatic conveying system transports grains from the warehouse to the processing area quickly and efficiently, ensuring a smooth production process.

 

Dense phase vs. dilute phase pneumatic conveying systems

The following is a direct comparison between the two to help you make a clearer choice:

Feature Dense Phase Pneumatic Conveying Dilute Phase Pneumatic Conveying
Conveying Speed Low speed (<10 m/s) High speed (10-30 m/s)
Pressure Requirements High pressure (1-6 bar) Low pressure (0.2-1 bar)
Material Wear and Damage Minimal, ideal for fragile materials Material may experience more impact, suitable for durable materials
Pipeline Wear Low due to slow material movement Higher wear due to fast airflow and material movement
System Complexity More complex, with higher installation and maintenance costs Simpler system, lower maintenance costs
Suitable Materials High-density, fragile, or abrasive materials Lightweight, non-fragile materials like plastic granules, powders
Energy Consumption Lower energy consumption, more efficient Higher energy consumption, especially over long distances
Conveying Distance Suitable for short distances (<100 meters) Suitable for long distances (>500 meters)

 

How to choose the right pneumatic conveying system?


When choosing between dense phase or dilute phase pneumatic conveying systems, the following key factors must be considered:

Material characteristics: If the conveyed material is fragile, abrasive, or needs to maintain its physical shape, a dense phase pneumatic conveying system should be selected. For less dense, less damage-resistant materials, a dilute phase pneumatic conveying system is a better choice.

Conveying distance and speed: For scenarios that require high-speed, long-distance conveying, a dilute phase pneumatic conveying system is more suitable. Dense phase pneumatic conveying systems are suitable for short-distance, low-speed, delicate conveying.

Cost and maintenance: Dense phase pneumatic conveying systems have a higher initial cost, but perform better in reducing pipeline wear and improving material integrity. Dilute phase pneumatic conveying systems are more suitable for projects with limited budgets and low maintenance requirements.

Environmental requirements: If the conveying system requires a high protection level (such as IP67) or anti-electromagnetic interference scenarios, dense phase pneumatic conveying systems can provide better sealing and stability. Dilute phase systems are more suitable for routine conveying tasks without special environmental requirements.
