Its working principle is: the road shot blasting machine uses the motor-driven shot blasting wheel to generate centrifugal force and wind force during high-speed rotation. , the projectile is thrown into the directional sleeve from the window of the pilling wheel, and then thrown through the directional sleeve creation library, picked up by the high-speed reversing blade, and continuously accelerated along the length of the blade until it is thrown, the thrown projectile constitutes a certain The fan-shaped flow beam, which impacts the working plane, has the effect of finishing and strengthening. Then the projectile and dust and impurities pass through the rebound chamber to the top of the storage hopper. The high-power dust collector separates the pellets from the dust through the separation device above the storage hopper. The pellets enter the storage hopper for continuous recycling, and the dust enters the dust collector through the connecting pipe. When the dust enters the dust collector, it is separated by the filter element and stays in the dust storage bucket and the surface of the filter element. The active backflushing dust collector can actively clean each filter element by the backflushing air provided by the compressor. Finally, through the airflow cleaning of the matching vacuum cleaner inside the machine, the pellets and the sorted impurities are recovered separately, and the pellets can be used again. The shot blasting machine is equipped with a dust collector, which can achieve dust-free and pollution-free construction, which not only improves the power, but also protects the environment.
