The dilute phase pneumatic conveying system is a universal core equipment for achieving closed transportation of powder and small particle materials in industrial production. It relies on the driving force of high-speed airflow to keep the materials in a suspended state for transportation. The entire process is powered by gas flow energy, and with the core characteristics of low solid gas ratio and flexible conveying path, it has become a key supporting facility for various industries to achieve clean material transportation and promote production process automation. The system can be divided into three core types based on production conditions: positive pressure, negative pressure, and positive negative pressure combination. It can accurately adapt to different production scenarios such as single point feeding and single point unloading, multi-point feeding and multi-point unloading, and meet diverse material conveying needs. The system adopts modular design, with the core consisting of gas source equipment, feeding device, conveying pipeline, gas-solid separation and dust removal device, and PLC intelligent control system. The layout can be customized according to the production site and material characteristics, with strong adaptability.

In terms of performance and advantages, the dilute phase pneumatic conveying system has a simple structure and is easy to install on site. The fully enclosed conveying process avoids dust pollution from the root, meets the requirements of green production, and has a high degree of automation, greatly reducing manual intervention. At the same time, the system can also synchronously complete auxiliary processes such as cooling and drying during the transportation of materials, achieving the integration of material transportation and process processing, and improving production efficiency. This system is widely used in many industries such as food, building materials, chemicals, electricity, pharmaceuticals, and grain storage. It is suitable for dry and flowable non abrasive powders and small particle materials. It also supports customization of various materials such as carbon steel and stainless steel, adapting to the material characteristics and production requirements of different industries. In addition, the system is equipped with comprehensive safety facilities such as explosion-proof and pressure protection, which can ensure long-term stable and safe operation. Daily maintenance and operation are simple, and it can also provide customers with one-stop professional services from preliminary scheme design, mid-term installation and commissioning to later after-sales maintenance, fully meeting the material transportation needs of industrial production.
