Technical Field

The air flow mill consists of a base, a silo, a feed pipe, a connecting pipe, a screw feeder, a short pipe, an operating table, a crushing chamber, a motor, a grading impeller, a discharge pipe, a supersonic Laval nozzle, and an induced draft fan. The raw material is transported from the feed pipe to the silo on the base, and the raw material enters the screw feeder through the connecting pipe by its own weight. The motor drives the auger to make it fall from the short pipe into the crushing chamber of the operating table. At the same time, the compressor gas is dried and connected to the supersonic Laval nozzle, so that the air flow is blown from bottom to top, so that the raw material is blown up, and the motor is started to drive the grading impeller to rotate, and the raw material is crushed. After meeting the requirements, it enters the grading impeller and is sucked away by the air pump connected to the discharge pipe. At the same time, the purified air is discharged by the induced draft fan, thereby reducing the dust in the surrounding environment to achieve low emissions.
