The working principle of the pneumatic tanker is that the engine transmits power to the air compressor through the transmission device, compressed air enters the tank, and the powder material is fluidized through the fluidized bed.

When the pressure reaches 0.2Mpa, due to the pressure difference between the inside and outside of the tank, the powder materials are transported along with the air to the designated position outside the tank through the discharging pipe. Fast discharging and low residual ash rate are the advantages.
