What is Pneumatic Conveyor?

A pneumatic conveying system uses air as transportation power to convey bulk solid material in the pipe.

Benefits of Pneumatic Conveying System

• Variable arrangement of the pipe makes the production process more flexible.
• The system is sealed and no dust emission, it benefit for environment protection.
• Few movement parts, convenient maintenance, automatic control can be realized easily.
• High efficiency of transportation reduces the cost of packing, loading and unloading.
• Prevent the material from being damped, polluted, damaged and mixed with other material, the quality of conveying is assured.
• Multiple operation process can be realized meanwhile for the conveying, such as mixture, crush, grade, dryness cooling, and dust collection.
• Send the material from several locations to one location or from one location to several locations, easy for long distance operation.
• For the material with erratic chemical character, can adopt inertia gas for conveying.

The state of the pneumatic conveying system refers to the movement form of the material in the pipeline that changes with the change of the conveying air volume during the movement of gas-solid two-phase flow. When the wind speed is higher than the material suspension speed, the material is in a suspended state and is evenly distributed and moves with the airflow; when the wind speed begins to decrease, the material begins to settle and agglomerate; when the air volume further decreases, the material begins to gather in the pipeline in the form of a group, showing a pulsating state. When the wind speed continues to decrease, the lumpy material begins to block the pipe section and forms an unstable plug, which is transported by the pressure of the air. If the wind speed is further reduced, the material will become a stable plug, which is driven and transported by the pressure of the air. If it continues to decrease When the wind speed and pressure exceed the rated pressure of the air source, the pipes will be blocked.

The status classification of the pneumatic conveying system is based on the movement status of the material in the pipeline, which is divided into three categories: suspended flow transportation, dense phase flow, and plug-flow transportation.

Dilute phase (Suspended flow)

Dense phase flow (group flow)

Plug-flow

The choice of conveying type is related to the characteristics of the material, conveying distance and other parameters. The conveying method can be selected according to the actual site conditions.
