Cement powder pneumatic conveying is a specific application of fluidization technology that utilizes the energy of air flow to transport powder and granular materials along the direction of air flow in a closed pipeline. The pneumatic conveying device has a simple structure and is easy to operate. It can be used for horizontal, vertical, or inclined conveying. During the conveying process, it can also perform physical or chemical operations such as heating, cooling, drying, and airflow classification of materials simultaneously. Cement unloading ships generally use negative pressure suction type. Powder pneumatic conveying manufacturers can ensure the quality of cement itself. As the pipeline is sealed, cement will not be oxidized or sucked into water vapor, which will affect the quality of cement. When transporting cement at the same time, there will be no dust generated, and the dust will not be discharged into the atmosphere, polluting the environment.
