Star unloader unloader for the installation of the work under negative pressure discharge opening at the upper acceptable discharge discharged materials, relying on rotating impeller plays a role in the transportation of materials, but also bears the seal of a role in preventing pneumatic conveying process from the discharge opening of the intake air, to ensure the normal discharge discharge as a special unloading equipment, cleaning and cleaning work has played a significant role. So we need to summarize some of its features, so that you can better be done on the star unloader comprehensive understanding and maintenance of its greatest capacity. Star discharge of materials can be used in the collection system, as a silo unloader. Star unloader is currently the most advanced discharging device, commonly used in the system as a dust removal system is one of the important equipment. It is particularly suitable for dust, small particles of material, by environmental protection, metallurgy, chemical industry, food, cement, road construction, drying equipment and other industries to select the best projects.
