Pneumatic conveying Roots blower
? ? The type of pneumatic conveying fan is determined based on the conveying process, and it is the air source equipment of the conveying system; The negative pressure pneumatic conveying system adopts the form of negative pressure suction. The Roots vacuum pump installed at the end of the system serves as the air source equipment. After the fan runs, the entire system forms negative pressure. The pressure difference between the air inside and outside the pipeline is sucked into the conveying pipe; At the same time, the material and a portion of the air are simultaneously sucked in by the suction nozzle and transported to the separator. In the separator, the material is separated from the air, and the separated material is discharged by the rotating unloader at the bottom. The unseparated fine particles enter the dust collector for purification with the airflow. The purified air is discharged into the atmosphere through the muffler installed in the system.
? ? In the positive pressure pneumatic conveying system, Roots blower or air compressor is used as the system air source equipment and installed at the feeding end of the system. Due to the fact that the gas source equipment is located at the front end of the system, materials cannot freely and smoothly enter the conveying pipe, and a sealed feeding device must be used. Therefore, the feeding device of this system is more complex than the suction type; After the conveyed material is compressed and delivered to the conveying destination, it is separated in the separator or storage bin and discharged through the unloading device. The compressed air is purified by the dust collector and discharged into the atmosphere.

?? The model and type of pneumatic conveying fan are selected based on the characteristics of the conveyed material, conveying volume, conveying distance, etc. If you have any questions about the selection, you can call us. The broad understanding of the selection of pneumatic conveying fans refers to the structural form of Roots blowers, while the narrow understanding refers to specific products and performance specifications. As standalone equipment required for the composition of pneumatic conveying systems, their quality directly affects the stability of the system. Therefore, each standalone equipment should be taken seriously, only in this way can our pneumatic conveying production line be more stable.
