The rotary feeder pneumatic conveying device belongs to dense phase medium pressure pneumatic conveying and is widely used in the casting, chemical, pharmaceutical, and grain industries for conveying materials that are not easily broken. The pneumatic conveying device, along with the conveying pipeline, spherical three-way booster, pressure increasing elbow, and other components, form a sealed conveying system that can be equipped with an automatic control electronic control system to achieve unmanned control of the entire system and cooperate with PLC automatic control.

The various solid material conveying pumps, flow distributors, and receivers used in the rotary feeder pneumatic conveying system are very similar to the operation of fluid equipment. Therefore, most pneumatic conveyors are easily automated by a central control console. The pipeline is continuously blown by the flowing air flow to prevent microbial growth and reduce pest infestations. It can perform process operations such as impurity removal, dust removal, and cooling while completing the conveying operation.

The pneumatic conveying system of the rotary feeder can be designed according to the properties of the conveyed material provided by the customer, such as conveying distance and conveying method. The appropriate equipment can be selected, and its working principle is to use the kinetic energy of the airflow to suspend the granular material in a suspended state, and to transport it in a plug or sand dune shape along the pipeline with the airflow. According to the feeding method, pneumatic conveying can be divided into three types: suction type, compression type, and mixed type.
