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. Common type star unloader: can be used in ambient temperature is usually below 80 degrees on the material and it can continuously evenly into the conveying tube feeding, and in the system and separation collecting department, which in turn can be used as discharge function . Temperature-type star unloader: According transportation and material under the spout of the temperature rise due to temperature differences affect the quality of the body's expansion, as well as unfavorable bearing and seal system, our factory-type exterior design of the high-temperature structure Star discharge, it is part of the operating contact with the material of the box section separated, can safely operate the bearing and seal system is not working properly cross-temperature impact, such products will not only heat, but also because of the suction temperature for of materials and metal powder delivery and acceptance, has a good effect because such objects have penetrating, penetrating straight into the bearing seal device materials, resulting from damage to the mechanical operation, it has exterior features, it does not Council and the material contact.
