The star shaped unloader is used to be installed at the discharge port of the unloader working under negative pressure. The upper part receives the material discharged by the unloader, and relies on the rotating impeller to transport the material and also plays a sealing role to prevent air from being sucked in from the discharge port during pneumatic conveying, ensuring the normal discharge of the unloader. As a special unloading equipment, it plays a great role in cleaning and washing work.
