(Summary description)Pneumatic conveying equipment is generally composed of receivers (such as throats, suction nozzles, transmitters, etc.), conveying pipes, air ducts, separators (commonly used are volumetric and cyclone types), and air locks (commonly used are flippers. Plate type and rotary type, which can be used as feeder and unloader), dust collector and fan (such as centrifugal fan, Roots blower, water ring vacuum pump, air compressor, etc.) and other equipment and components . The function of the receiver is to enter the material, resulting in a suitable material-gas ratio, so that the material can be started and accelerated. The function of the separator is to separate the material from the air and sort the material. The function of the air lock is to uniformly supply or discharge materials, and at the same time prevent air leakage. The role of the fan is to provide power to the system. High-pressure centrifugal fans or water-ring vacuum pumps are commonly used in vacuum suction systems; Roots blowers or air compressors are used in pressure-feed systems.

When the material moves in the updraft, the material descends by its own gravity, but the updraft gives the material an upward force, which is the lift force. When it is equal to the lift force received by the material, the material will be suspended in the air flow and will not rise or fall. When the gravity of the material is less than the lift force received by the material, the material will rise with the air flow. The greater the lift force, the faster the material rises. This is the basic production principle of pneumatic conveying equipment.
