The electric impeller unloader, also known as an airlock, is an important device in pneumatic conveying and ventilation dust removal systems. Its main function is to continuously and promptly discharge materials from the unloader or dust collector while preventing external air from entering these devices. The electric impeller unloader is widely applicable in industries such as rice milling, flour processing, feed, chemicals, pharmaceuticals, tobacco, metallurgy, and cement. It plays a role in the continuous discharge and air-tightness of powdered, granular, flaky, and fibrous materials under positive and negative pressure conditions.
